<pre wrap=""> I have a CentOS 5.6 system (recently installed) that, for some
reason, has decided to mangle one of its drives, specifically /dev/hde1
... 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?<br>
