My father's pc hung(mouse and num lock didnt work anymore) this morning when i put the screen on (it was already running an hour or so, but not doing anything) . Its and athlon 1800+, abit kd7, maxtor 80gb 80mb cache hd, win2K pro sp3. I rebooted it and now, everytime it's supposed to start loading from hd, it gives an error message disk I/O error Status : 00001000 NTDETECT FAILED i booted the pc with a win98 boot disk and when i look around, it seems like the c partition is lost or something. a: and b: are diskette drive, on c: i find my old d partition (i have 2 partitions on my drive), e: and f: are cdroms, it tried other drive letters but it seems my windows partition is lost or so. Although when i use fdisk and look at the partition information it shows the 2 partitions and everything seems to be normal here. can anyone help me out on this one ? Is the hd dying(bad cluster or so) ? is this a problem with the boot manager?
