I've been lurking on this list for a couple of months trying to learn about Linux. I now have a problem which I believe is unrecoverable, but I would like to know if I did something to cause it. I had a computer running FC3 and a week ago Saturday I shut down the computer while I went on vacation for a week. When I got home I booted the computer and used it for several hours. I then ran up2date and it seemed to be successful. I decided to reboot and when I attempted to log out, the computer appeared to lock up. I pushed the reset button and when the computer attempted to reboot, I got a grub prompt. I used the rescue cd to run linux rescue and it said that there were know linux partitions on the drive. I ran sfdisk on /dev/hda (the drive on which FC3 was installed) and got the following: Checking that no-one is using this disk right now ... BLKRRPART: Permission denied OK Disk /dev/hda: 79656 cylinders, 16 heads, 63 sectors/track Old situation: Warning: The partition table looks like it was made for C/H/S=*/255/63 (instead of 79656/16/63). For this listing I'll assume that geometry. Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/hda1 * 0+ 12 13- 104391 83 Linux /dev/hda2 13 4997 4985 40042012+ 8e Linux LVM /dev/hda3 0 - 0 0 0 Empty /dev/hda4 0 - 0 0 0 Empty Any ideas would be appreciated? Just for informational purposes, before I installed FC3 I was running WinXP and it crashed also. That's why I installed FC3. Is it possible the hard drive is bad? Craig Herman
