can a virus cause unrecoverable damage to HD?





yule
I have been working on a laptop for 4 days now. I have run Mcafee AV and AVG 7 alternately and have found over 40 viruses,trojans etc. I have run Adaware, Spybot S&D and a few specific fixes. The first AV scan w/McAfee took over 24 hours on a 20G hd with only 8G being used!!

Today, when I restarted the laptop I got a stop error. That problem was dealt with with Dell and they are sending me a new hard drive. My question may sound dumb, but can a virus actually cause an unrecoveable error to the point of having to replace the HD or was this a coincidence that the HD crashed when I was doing all this work?

thanks for any input. Crying or Very sad

Some viruses or trojans are known to sometimes cause damage to hard drives I have read about this before on another forum.

You sure the virus didnt attack your bios?.

Some viruses are claim to be capable of changing voltage on your main board - I'm not sure its true but if it is, then some of them can damage your HD. But its just a rumor.
cnnet
I think so
some years ago
I heard it was possible from a paper
but I never met this
jgarder
it is possible.. if the virus or trojan loads up a very basic program, it can edit your bios to make your computer think the harddrive is way faster then it is.. the harddrive will usually spin very awqwardly and invalid data willl be sent//received as a result, although this is a very uncommon virus because it is very motherboard manufacturer specific.. IE asus made virus's will only affect asus mobo's

usually no physical harddrive damage will occur, you usually just reset the bios with a quick flash or get a new motherboard :/

A virus cannot directly or significantly effect anything beyond that which is manipulatable via data I/O. Period. Any damage to a HDD or processor would be limited to what changes can be made concerning said hardware. (For instance, a virus could cause a continuous load on the processor, HDD etc and cause damage from heat or other effects of 'over-revving'.
cronic5
Like S3nd K3ys said, It can't cause direct damage to your hard drive but can cause indirect damage to it. I have known many people who have been able to write a virus like this. Although many of these are very rare, they are out there. That is why i recommend not having McAfee and having some other anti-virus program like Norton. I also recommend having a firewall. There are many good free ones out there. Last, I recommend having an operating system such as Linux (mainly Gentoo or Fedora Core) because they are much less likely to have a virus (since many viruses are written to harm Windows).

I agree on this one, but the software I use for my work will not run on anything but windows. So I am forced to have a windows box. I do have a box at home with Fedora on it, and dabble with that some. But unfortunately, windows is my OS de jur.

Virus doesn't damage your computer. It's just a virus. I have an antivirus and it notifys me often when the virus comes. It didn't damage my computer. Just use the best antivirus as it's possible and ignore the virus if it's keep annoying you. That's what I do.

Some viruses take control of the boot system. The boot of hd is the part where are stored the data from that the computer starts. The computer reads this information before star the operating system and of course, before to start the antivirus software. So, if a virus gets that place, there are many probanilities that your pc is dead.
darkeagle
Yeah some viruses and trojans may cause any damage on harddisk.
For example trojans are openinig your ports and other users can be connected your computer.
When they are connected, they will be changed your bios configuration and this may cause a damage on your harddisk or any part. They will be formatted easily your harddisk too.
For security you must be clever Very Happy
m_furquan36
A virus attack can deifnitely damage ur hardisk, but trojans cannot, they just merely play around with ur files on ur harddisk. Some Virusses can attack ur BIOS, as stated earlier, and can also damage ur harddrive clusters, meaning like damage the data present on that regeon of the hard disk, meaning the data gets irrecoverable, and furthur more, writing data to that portion of the harddisk becomes impossible, even though that section of the hdd is clearly contributing to the over all space statistics of ur harddisk

And also, 24 hours for 8 gigs of data is waay too much, i would suggest ur use a software called:

Registry Cleaner Optimizer by Palsol

Thatl clear out all Slowdown problems of ur hdd and computer, believe me i cleaned out 24000 registry entries, and didnt realize it was my registry which was giving a hell of a slowdown on my system! Rolling Eyes Wink
poggendroff
wen ur comp is hacked, its usual to see cd roms going in and out randomly,,floppy drives starting and shutting on their own. fan speeds can be adjusted via bios,, so obviously temperature can be raised inside the cpu. so yes dude,,viruses can damge ur hdd, in case u dont clear them up
Bender1337
what u need to do is buy a sh!ty hd and set it as master then get the one that will not boot up and set it as slave now u will be able to acess that hd it works done it before
Crackr
yes a virus can ruin your hard drive, but only certian viruses
and also if you bought your laptop Used that will also be your problem...

i bought a used laptop once from an actuall computer store and it had an actual hard drive virus on it, by that i mean there was a Virus CHIP on the hard drive that allowed it to run for 5 days then it would delete everything and give me like 90 viruses that messed everything up... so thats another thing to look for

but thats my input man you can try other things but thats my idea

good luck with it bro

A virus cannot itself damage your hardware under a modern OS. HAL wouldn't like that.

As for your infection:

http://stopie.com
yjwong
I've had this problem before in Windows ME. The computer boots up for about 30 seconds then automatically shutdown without any warning.
Higgs
I'd say rather unlikely but not 100 percent impossible.

I think first the virus has to gain system privileges, execute in ring-0 whatever you call it, so that it's able to access the hardware directly.
Then the virus needs to know how to damage your specific hardware. Like sending some manufacturer dependant command sequences to the device that sets it to an error state or using some mechanism thats normally used for flash upgrades, but that could be also used to corrupt the firmware of the device. E.g. it's well known that you can flash a lot of cd drives. A few years ago there were also viruses that corrupted the system bios on some boards in a similar way I think.
Another problem might be low level formating of the hd, which could lead to errors on modern drives. Ok, maybe this issues are also history.

So my conclusion is still, that it's extremely unlikely, that a virus executes with system priviliges in XP for example and has also the right code in it, to exploit some manufacturer specific stuff to damage your hard drive. But this is just what I think about it at the moment. Don't know much about the latest virus problems.

lol??? I mean, a virus CAN definitively cause hard disk problems, and not just that. It can mess with BIOS.., With the voltage and velocity of the computer, make a dangerous overclock that can "burn" your CPU... For example, did you know that there are monitor virus? That they put themselves in the monitor memory, and that makes them harder to delete. Besides, if the virus keeps annoying you, you ignore it? That's so cool. Your computer must be the most protected computer in the world if you still using that theory in the world we are!

That's not true. Trojans can damage your hard disk when you turn on your computer next time using a timer. To avoid this there are online magazines like Astalavista Security Group, that informe you how to be an hacker in order to understand and protect yourself from virus, hackers, spywares, adwares and stuff like that.

Um, no. It is physically impossible.

Virii are data, virtual thingys that open and close virtual 'gates', Hardware is, um, hardware. I can't imagine a virus opening the CD door and smacking the computer with a hammer... Rolling Eyes

Post proof that physical damage can be caused directly by a virus. I'd love to see it.
S3nd K3ys
After further research, I found NOTHING that stated, other than ignorant posting on forums like this, that proves a virus/trojan can cause physical damage to a HDD.

Quote:
Q20. I heard the so and so virus and others can damage my hardware/system. Can they?!

True/False = FALSE!

A. This is a popular myth. Unfortunately, even with people posting rewards, no one has ever produced a virus that can physically damage a computer. They simply don't exist. They may erase data or similar, but this doesn't require a new hard drive. It's simply an inconvienience that is easily recoverable. The only physical damage that might result would be the headache you might get from having to recover from this because you forgot to practice Safe Hex

Let's put things in the proper perspective. A virus or trojan is nothing more than a piece of software. Software is something nonphysical for the most part unless you include the ROM's in your computer. For a virus to damage hardware, it would have to create a physical entity, a gremlin so to speak. It would then have to emerge, unbolt the cover to your hard drive or whatever, step in and start hitting it with a hammer. You show me a virus that can do that and I'll eat radioactive waste daily and live. The likelihood of either happening is null unless the physical laws of the universe change overnight. 8*) (index)

Of course it can!


If with C you can play with the LEDs on your keyboard then what's the problem with damaging a little microchip? making an overload?

it is possible in some ways if you think about it..


btw "hardware" and "virtual things" sure are connected.

Post proof. Seriously. I've even got an old PC I'll 'donate' to the cause to prove it.

There is none. There's been rewards offered for someone to write one, and NONE have been produced.

BTW, how does the ability to turn on LEDs (which are 'switched on/off' with software in the same manner images are displayed on a monitor) equate to being able to create a physical entity which can cause physical damage???
noliver
Nope, I would have to say that a virus can not physically damage a computer. Thats rubbish. The worst I have ever seen a virus do was to mess up the directory tree of a hard drive. If you know what you are doing, you can get that back with the right FDisk command.

As for flashing lights in the keyboard etc. That is a logical condition triggered by a command. There is no way that a virus can do those things and damage the computer. I have never seen a virus ( and I have seen plenty ) that could change BIOS settings and all that.

So, until I see a virus physically changing hard drive settings or Bios settings, I will have to go with - it can not be done.
THE11thROCK™
Yeah, I certainly believe too that no virus can directly destroy your hardware. Most of the times AVG, Norton, Panda and Mcafee cannot clean them all - solution - clear the CMOS and reformat.

There's a widely popular hardware encrypted Harddisk by Excelstor that handles viruses and trojans with a better hardware incorporated security system. I believe they are using a higher technology than the IBM which embeds security with hardware encryption.

With the FDISK, yeah, I use it. It's a great harddisk formatting tool.

With the trojans, I certainly believe that they are less powerful than a worm or virus. But when it is already controlled by the hacker (using it as backdoor) you're in deep trouble. The hacker can definitely ruin your software system by bombarding you with viruses or simply spying on you or simply erase datas or steal them.

For the curious, you can check the worse products of hackers' work.

isn't the clock speed of the modern graphics cards adjustable from within windows ?
also I've seen certain programs (clockgen, softfsb) that can change the cpu & fsb speeds through the clock generator on the mobo, also from within windows.

I think it should be, theoretically, possible to damage hardware through software. But like most people here said, I'm yet to see it done.

Answer is YES.... reason why? For 'ordinary person' Laughing as myself , they damage harddrive clusters,because virus can more times used same cluster for same 'bull shit' operation.Your HDD working one day as for example one month.... after one month as 3 years and every HDD have time for life Laughing

Um, you're talking about normal wear and tear. We're talking about a virus/trojen DAMAGING a HDD or other hardware.

Watch it, this is possible.

Not only your hard disk can be damaged, but other devices too... Hard Disks, Graphic cards, even monitors can be damaged...

The virus should just keep pushing up stressing the devices, turning on and off (can't be made directly, but through the motherboard signals), and you can get your devices damaged...

No not now a days. With the older harddrives some times a virus could be written to cause the arms to travel farther then they were designed, thus breaking, or rendering the drive useless in the process. Now like 100% of HD manufactuers have built in stuff where this isn't a problem anymore. And this has been the case for quite a while now.


And as for the post above, yes as I stated above, it was somewhat possible at one time until makers wised up. Your not just gonna write software to do anything.

The nastiest virus I've ever heard of--I don't remember where--used various system internals to draw so much electricity onto the motherboard that it basically destroyed the computer. Shocked Virtually anything is possible if you know what you're doing.

Are you sure it wasn't just urban legend? I once heard about a virus that was supposed to change the magnetics in your harddrive, thus creaming your system and blanking out any magnetic strips on credit cards laying around next to your computer. It was nothing more then urban legend.

Like I said, some stuff was possible with older hardware, but most of that is taking care of now a days.

Maybe it's not possible now but may be possible in the future.

What they do mostly is affect the boot sector of your drive.
They can also re-write your bios.
You can avoid these two issues by turning on the two protection settings that can be found in bios itself.

One is called Virus Protection as it won't let anything re-write the boot sector, the other won't let your bios be flashed by anything until you manually change the setting again.
Omego2K@
can a virus cause physical damage to a hard drive or other hardware? Theoretically, yes. Those viruses are even probably out there, although I don't know of any. If a virus say overclocks your video card (makes it go faster), it can fry it. Although it's not possible to do it to your cpu, since you have to overclock it from your bios. I'm not sure if you can overclock your hardrive, but I assume it's possible.

I just got a gigibyte(spelling) motherboard. It has software included with it so you can over clock the computer from the desktop,...in real time, not talking about having to reboot.

as far as hardware is concerned most manufactures are wise to these old tricks. For instance if you try to overdrive a monitor it will simply shutoff, a lot of times it'll display a "signal out of range" message.

again you're not gonna make hardware do what it is not pysically capable of doing. In the past harddrives were physically cabable of having the arms travel past their intended arc, thus damaging them, if the right signals were sent to the controller. It was a friendlier world then and HD manufactors never considered it. Why would someone write code to damage their own hard drive. After virii started coming out that attitude changed. now it is impossible for like 99% of harddrives since there are pyshical mechanisims built into the hardware. I say 99% because who knows what generic harddrive manufactor decides to skip costs/corners.

this goes for most hardware now a days. Its more likely to be damaged by missuse or overuse, such as dropping it or too many games of quake lol, then by a virus
guitarnut
Yes it can I have had it happen to me, some viruse's can cause the read heads to crash in to the platter's.
technology.sponge
though is is possible for viruses to change bios/voltage/config or firmware
they are EXTREMELY rare and are quite obvious when in action

most of the time, the only damage viruses would do is shorten you hdd life by 3 hrs from constant read/write
Pikokola
directly no, but indirectly is yes Smile

I think somebody already tell you about it before me, but let me makes it simple

You absolutely can change your Pc performance (usually people call it overclock), since overclock have effect on the performance of your PC (it's usually give better performance), ofcourse it's have another side effect, such as overheating, malfunction, until hardware broken.

And the virusses, since vurusses have so much way to do to your pc, it's might be do that things to your PC Very Happy
Welll. i hope that's clear it all Smile
EssoHome
Many Windows versions ago, Win 98 I think, I made a program that would automatically overclock a very old Intel CPU whenever I started Roxio. (Reason it took forever when working with Photos or Video). It worked very well until one day I received an alarm that the CPU was above 60 deg C. If I can do it as an amateur I am sure their are bad guys out there who could spread a similar program around.
I believe that most modern CPU's have safeguards against this.

I once saw a virus which would open and close the CD tray repeatedly.

This kept on happening and finally thetrya got damaged.

I'm not sure if it was because someone tried to block it opening with their hands or just by the repeated pening, but it got damaged anyway



ABout damaging the hard disk, if it does something to sector 0, I thing the hard disk can suffer damage.




Some viruses need to be erased in a spesial way, overwriting all the data on the hard disk - a simple format will not work - so I suppose they also cause some sort of almost irreversible damage.

I honestly don't know much about sector zero and these viruses, but look them up in Wikipedia if you are interested
jdelfire
this is very uncommon..................

ejecting cd rom is easy because u are already inside the operating system and there are program or commands that are free and can be used to eject cd rom....... try to imagine this create or reverse engineer a software that would loop your command to eject the cd rom....
"http://wareseeker.com/free-eject-cd-command/"

same concept with you installing two or more cd games disc on your system after your finished on installing the first disc cd rom automatically ejects and ask for the next disc but this is a basic function of the cd rom so dont be stupid to let it repeatedly ejects it..... virus destroying hardware is not a basic function.

about virus physically damaging ur harddrive or any other hardware on your system thats gonna be very rare............ because there is no generic BIOS(basic input/output system) they have to do this before windows load or os load... so the only chance for it to work is to FLASH your motherboard bios create a command tat would exploit the bios settings lets say by disabling the FAN on your board or technically blacking out your motherboard........ (i usually do this when i have a motherboard that i want to be replaced from a computer shop or get a warranty from it totally untraceable) so going back for a virus to mess up your system they must get the BIOS first because thats the first rule......... to make changes in the I/O of your system.... or they will ruin your harddrive partition................. which can be fix by recovery partitions.

why do a lot of people start shouting 'get another OS' on any question that people ask?
I have read so many posts that directly start with 'get Linux'. The question here is if a virus can damage a hdd. Not if Windows is more likely to get a virus.

i think if a virus can reach bios level it can damage hardware. if not, i doubt it.
Jamestf347
I don't believe it's possible but yet... what's not? The most i can think a virus can do is format your drive and possibly attack the MBR but then again who knows, new things are coming out daily.

Flashing you bios simply means upgrading or replacing your motherboard BIOS (Basic Input Out System). You can get it from your manufacturers website. So why do we need to flash BIOS for two common reasons hardware and software incompatibilty or better system improvement. for example you have a legacy computer a dell dimension system which happens to show a blinking a cursor and can't boot to windows after installing a new printer(mostly usb 2.0 enable). What we normally do is upgrade the BIOS of the board to make it fully compatible.

Other examples of errors why we need to flash the BIOS
Fixed the issue that HDD LED is always bright.
Fixed the issue that SATA HDD runs at PIO mode under OS when SATA mode is selected in BIOS.
Changed default option of BIOS APM Configuration - Restore on AC Power Loss to Off.
Patch system halt issue when using four IDE HD and one SATA HD.
Fix EIST function issue when C1 Stepping Cedar Mill or Presler CPU is used.

There are two ways for you to fry your motherboard
1. While your bios is updating and there is a power failure. (which i intentionally do if i want to get a motherboard replace)
2. Using a corrupted or incompatible BIOS.

In relation to this thread come to think of it BIOS can be overwritten so if thats the case through software you can actually mess up your hardware but then again this is a rare scenario.
something to read about virus flashing bios http://lists.bilkent.edu.tr/cih/alert.htm

sorry double post had to edit

In fact "Virus Recycled" made one of my colleagues' HDD unusable. The problem was that TOC was imposible to change, no matter what software you used to reset it, the TOC remained unchangeable.
Jaan
Physically it can only be damaged by wear and tear... otherwise harmful settings would have to be changed.
for example it might constantly duplicate files and fill the hard drive to capacity, delete them, start over (having your hard drive with less than twenty percent free space is bad for the computer/hard drive)

cheers, this is an interesting topic ^^

Why was this dug up, the original question was posted 4 years ago, and the poster is banned.
albuferque
Geez, you're right. I haven't noticed it.

However, it was just to tell some of my friend's experience with TOC.

FunDa
Whatever happened to the orginal poster does not matter in the end, because it is a very interesting point of discussion whetehr a virus can cause physical damage.

Like I already noted, yes, it can

It destroyed the CD drive physically in one of my friend'c computers.

And fromthe discussion it looks like it can damage hard disks too.

And overheat the motherboard.
PCDOC
OK, I know the original poster is no longer here but let’s clear the air...

a VIRUS is a line or lines of CODE. In other words it is a computer file. So with that said… other than making a piece of HARDWARE run continuously, which is caused by corrupting the hardware’s operation file called a DRIVER. Which COULD make that piece of HARSWARE overheat. There is nothing and I say again NOTHING a virus can do to damage a piece of hardware. There are NO files within a CD drive, to be infected. ALL files on a HD are replaceable and the BIOS is NOT located on the HD. Not to mention, your BIOS is protected. (Any of you that have ever had to FLASH your BIOS know what I mean) If any of you think logically about this you would know that you DO NOT even need a HD to operate a computer. Yes, you may need an HD to load WINDOWS, but if you really know what you are doing, you do even need windows.
For those of you still reading this, the original poster most likely deleted a ini file, sys file or other command file in the boot sector in the process of cleaning out the viruses. He could have solved this problem by doing the following.

1) BOOTING from a OS disk
2) Doing a format C:/ from command prompt
3) Reinstalling his OS and other software.

Yes, he would have loss all his personal files, but this is why you always see people pushing BACK UP! BACK UP! BACK UP!

I hope this cleared the air for all you that don’t have a clue as to what you are talking about.

To PCDOC.

Although it is true that a HDD can not be physically harmed via virus, but with an open system like Linux, the HDD can be put out of commission. For example the "SMART" hard drive have bad blocks location written either on a protected section of the hard drive (this is NOT the same that format or fdisk works with) and/or written to a special section of the firmware. So it is where a piece of code can "damage" a hard drive. IF and only IF these locations are violated on, the HDD will indeed be destroyed but in a "soft" way. The only way to fix this is to either use a special "low level format" to rebuild this drive fault table, or IF the format program will work with this faulty table, is to re-format the HDD. I have seen many computers get this virus but was unable to find its name or where it came from. So far only open system Linux and for some reason one Apple computer was hit with this. My Linux OS named fedora was hit with is and I lost everything and many many hours of fixing the HDD. I have now found a way to do this but will not tell anyone on how to do this for fear it will lead to more virus attacks. So far the attack of this virus like thing came from what appears from India, but can not confirm it.
So the bottom line here is, yes a HDD can be made to mimic a failure, but you have to get really deep into the hardware of the HDD to make such destruction and IT DOES HAPPEN people. for a few drives my only option was to replace the HDD until I found how to fix it, thanks to the support of the HDD manufacture and their diagnostic tool.

May be it can but i've not experienced it yet

Viruses can cause un-recoverable data but it may depend on the error you get on boot.

Q20. I heard the so and so virus and others can damage my hardware/system. Can they?!

True/False = FALSE!

A. This is a popular myth. Unfortunately, even with people posting rewards, no one has ever produced a virus that can physically damage a computer. They simply don't exist. They may erase data or similar, but this doesn't require a new hard drive. It's simply an inconvienience that is easily recoverable. The only physical damage that might result would be the headache you might get from having to recover from this because you forgot to practice Safe Hex

Let's put things in the proper perspective. A virus or trojan is nothing more than a piece of software. Software is something nonphysical for the most part unless you include the ROM's in your computer. For a virus to damage hardware, it would have to create a physical entity, a gremlin so to speak. It would then have to emerge, unbolt the cover to your hard drive or whatever, step in and start hitting it with a hammer. You show me a virus that can do that and I'll eat radioactive waste daily and live. The likelihood of either happening is null unless the physical laws of the universe change overnight. 8*) (index)

I have to say that I actually found that part of the description not so serious although funny Razz

I believe that though.

i remember in the 90's there are some viruses can invected sector 0 on disk than the disk can't used for booting, and some viruses can remove all HD content.

so now is possible if virus cause damage HD

Exactly, so a virus can technicallyty do some damage.


I have seen viruses which open qand close the CD tray repeatedly till they get damaged (nobody knew how to stop it, so some people at school tried to block it from opening by using their hands)

I had in fact two computers, that where desktops that contained a virus and were inaccessible to the system operating systems, Both Windows XP and I just decided to throw away the hard-drives since the virus only damaged the hard-drives so Yes Its possible but its very rare to see that kind of virus..

that was back in 1999 around 2004 but I haven't seen it for a very long time so idk if its still possible. Since people (who make the viruses) have to be up to date on the current bio and system configurations to make such a virus

Ohhh my God !!!

Have u guys heard about the virus which can infect laptop batteries ?


It is not science fiction anymore, don't worry about hard disks getting irreversibly damaged and CD trays getting worn out.

Or even about motherboards being overclocked to overheat.


This new 'virus' can infect a MacBook laptop's battery and can potentially make it explode !!!

MacBook users laptop batteries are
vulnerable to being hacked. Security researcher Charlie Miller has been
studying the batteries in several MacBooks,
MacBook Pros and MacBook Airs and has
found that the Apple laptop microcontroller
chips are shipped with a universal default
password that can be used as a hiding spot for malware. This infection can lead to
disabling the battery and even blowing it
up. "The batteries just weren't designed
thinking that people will mess with them,"
Miller said "What's being shown is that it's
possible to use them to do something really
bad." Can you imagine hundreds of
thousands of laptops exploding at exactly the same time? Using passwords associated with a 2009
Apple software update, Miller was able to
permanently disable several batteries,
manipulate readings sent to the operating
system and charger, and completely rewrite
the chip's firmware. Miller stated that a hacker could easily install
malware on this chip and use the infection
to control the computer, steal information,
and use it to infect other computers, and
even though the batteries Miller studied
have safeguards against explosions, he believes that a Hacker could bypass these
safeguards making it possible to cause
them to explode on command. What complicates the issue is that these
Apple notebook batteries are not user
removable but built into the notebook.

Wow FunDa, now that is scary...

Aleast I don't have a macbook or whatever you call em, I'm simply windows forever! LOL<<

Making Batteries explode on command, in someone's face, wow... I bet that's harsh... someone goes to do something on their computer than it explodes and they have to go to the hospital, ouch!
