My Windows 2000 is full of errors and its about time to reformat the hard drive. I've done this many times before. I boot from cd first and then use their reformat program to reformat the Hard drive. Well, when I stick the disk in this time it says Disk I/O error= 000080000, then it reads the disk for another 5 minutes and repeats the same error over and over. I have never had this happen before and I am not sure why it would be happening now. Is there something wrong wtih my Hard Disk? Any help is greatly appreciated.
