I had a hard drive crash on an old machine. Attempted to re-install xp home. The computer goes to "copy files" to my hard drive and during this process, I frequently get "cannot copy file" messages. I retry and sometimes it works, other times not. This can be any file. Very random and it's not always the same file. I figured it was the disk at first, so I borrowed an xp pro disk. Same thing happened. I tried a hacked version of xp home and a hacked version of xp pro. Same problem. All these disks were free of scratches and have worked fine on other computers. I figured the hard drive was bad. I replaced the hard drive. Same problem. I just replaced the IDE cable thinking perhaps that was it. Same problem. I'm at a loss here. Anyone have any suggestions? I'm running a custom made system. AMD/Athlon xp 1.7ghtz CPU, 512MB PC2700 RAM, 400watt Power supply. Thanks in advance.
