SHOULD is right. I built a system for my sis and installed her old XP HD into it w/o a reformat. it worked swimmingly for 4 mos, then all of a sudden (boot drive) "Hardrive C is not accessible" errors, then crash. Wouldn't start in safe either. I reinstalled V64 onto the old XP drive after backing up the files and got the machine back running. Here’s what was odd, once the machine was working, it recognized the C drive, but still could not access it. I was able to run scan disk and able to perform a windows backup. However, the OS would not allow access to the drive. Weirdest thing I’ve ever seen. I've been searching forums all over, but I can only gleam a hint of what may of happened, but nothing concrete anywhere. I'm blaming it on my niece who's a limewire freak and assuming it was a virus. Whatever.
