how to recover the drive


I am running Fedora based Linux. Here is the Operating system version info:

Linux alpha 2.6.19-1.2911.6.5.fc6xen #1 SMP Sun Mar 4 16:23:59 EST 2007 x86_64?86_64 x86_64 GNU/Linux


The drive had a bad read but the drive was fine.
When I tried to reboot got the following error:
Logical Volume Management: /dev/sdb1: read failed after 0 of 2048
then it went into the prompt "Repair filesystem"
I tried to mount it manually
I tried to use different superblocks
by doing mke2fs -n /dev/sdb1 to show the superblocks
then using fsck -t ext3 -b 102400000 /dev/sdb1
but it still returned an error

Any help to recover the drive will be appreciated.

Usually what I do when I get asked to enter root password for maintenance after a file system check produced too many errors, I put in the password and at the prompt I type: fsck /dev/sdb1 and hit enter, then just keep hitting enter till it reboots. Basically accepting the default suggestions to the questions which is usually (y).

If you've tried several (backup) superblocks and got the same error(s), basically you can probably consider the filesystem (at least) as dead.
The physical disk itself may or may not be. I tend to move them to my test box when I don't trust them anymore - some last for ages, some never come good, and get thrown in the bin.

Forensic software may get some of the data back, depending on whether the disk itself is still usable. Takes a lot of time if you don't have a backup.
