No errors anywhere, just rebooted the machine over the weekend and it's gone. Up till the reboot, the drive was fine, I was writing to it without a problem.fdisk tells me: ---------- # fdisk -l /dev/hde Disk /dev/hde: 160.0 GB, 160041885696 bytes 240 heads, 63 sectors/track, 20673 cylinders Units = cylinders of 15120 * 512 = 7741440 bytes Device Boot Start End Blocks Id System /dev/hde1 * 1 20673 156287848+ 83 Linux ---------- There are no hardware errors in the boot log (dmesg). The only error is that it can't find the ext3 fs that was on that drive. Unfortunately, it's not a drive I can simply reformat and call it a day. There's data on it I need. When I try to mount it, I get: hfs: unable to find HFS+ superblock. Obviously that's not right as the drive was formatted as an ext3. So if I force it, I get this: ---------- mount -t ext3 /dev/hde1 /mnt/hde1 mount: wrong fs type, bad option, bad superblock on /dev/hde1, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so ---------- So, is this just an indication that the partition table is hosed? Is there anything, any tool, any way of reading the data off of this drive and put it elsewhere?Have you tried using an alternate superblock?
