i am using windows xp... p4 with 3 ghz, and 256 mb ddr ram. nw my computer's performance is very slow.. i checked for virus..and disabled all startup programes, still i have the same problem.. finally i found one error from performance log that found a bad block on my hdd. if i format my hdd will it solve the problem.
Formatting the drive 'may' fix the problem..sort of. It won't fix the bad block, but the format 'should' remove it from the master file table which should prevent the pc from writing to that block again. Do a full format, not a quick format. A quick format does no error checking.
The biggest problem is that the drive may be in the process of failing, in which case, more bad blocks may pop up. Almost like hard drive cancer.
Backup the data and change the harddisk immediately. There is no permanent cure of Bad block(except changing the media). It's truely a cancer of hard disk.
