I have a system that has a secondary scsi drive that had files shared with samba. One Monday morning these file abruptly disappeared. All that was left were 20 or so directory names but no files inside. Then hours later the directories themselves disappeared. After I umounted the drive and tried to run fsck or e2fsck but it wouldn’t run. It gave this error.
> Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb12. Could this be zero-length?
Then I did fsdisk to verify the disk.

>/sbin/sfdisk -V /dev/sdb

> read error on /dev/sdb - cannot read sector 0
/dev/sdb: unrecognized partition
sfdisk: no partition table present

Now I was told by a friend to run findsuper .

findsuper /dev/sdb12 512 0
Only problem is I don’t have that program.
Now I am at a stand still. Does anyone have any ideas where I can get findsuper or if that is the fix I should be attempting.
Thank you,
Kali

Sounds like your disk(or scsi adapter) is physically broken.

You can still try to recover something using gpart. Do not use findsuper.
Also the testdisk looks promising, but I don't have any experience about it.
