I was playing around with the permissions for different folders on my windows xp. I was going to create new accounts on my machine and wanted to restrict some folders. I went into safe mode and set my external hard drive to be blocked. However, it is now blocked by all users. I did a restore and can not get into it. However, I can see all the files but it will not let me open them. How do I reset the permissions for a drive on my machine? I went back into safe mode and set everything to full access but it didn't help. If anyone can help please post!
