Ok... I had left kazaa lite on, as i sometimes to, downloading a movie... i went downstairs for 3 hours, came back, and encountered a huge problem. I message box had appeared on my screen saying something like 'windows failed to delay write to E:/Video/Video Games ...blah blah...' E:/ is my slave hard drive... then at the bottom right, there was a yellow warning message saying something like 'windows failed to delay write to sector something, E:/$80EGsomething like that... blah blah'... i can't remember fully... and the desktop had frozen. So i pressed the reset button on my PC... When it shut down, it booted up to a power screen with that 'Energy' symbol at the top, and it was "searching for master (i assume hard drive)... then it found "none". Then it searched for "slave" and found "none"... which got me quite scared... then it went to the screen with the memory specs and such on it, and at the bottom it said 'insert BIOS boot disk in A:/'... well, i don't have a BIOS boot disc... my buddy has it... so i shut down the computer totally... then powered it back up, and everything was back to normal.......... Could someone please shed some light on this situation for me? I'm going to talk to my friend, but i wanna hear more then what he might have to tell me... Thanks everyone.
