[ale] bad XFS superblock

[Mike Panetta]

Does XFS have a way to supply an alternate superblock like EXT2 does?
if it does figure out what they may be and try one of them.  Another thing
to try (to rule out bad blocks on the disk) is to run badblocks on it.  If it shows
alot of errors the HDD may be in the process of going bad and you may need
to replace it.  If it just shows a few errors badblocks may be able to fix the issue by
moving things around on the disk a bit.

HTH,
Mike

My Suse 8.2 crashed M$FT style while I was using ymessenger.
When I tried to I reboot it, it gave an error (forgot the error but it 
mentioned the filesystem). I tried rebooting several times and then I tried 
using xfs_repair and xfs_check. Those attempts returned "bad superblock and 
input/output error." By googling and testing, I came to understand that I 
have a bad superblock. I tried mounting the HD on another machine - and it 
would not mount (or even be recognized correcty by YAST2.
However, the drive did get recognized by the BIOS, and if I use it as the 
master, grub comes up and it dies right about the time it is trying to load 
the filesystem.

I could not find anyone mentioning how to "fix" a superblock in XFS. Is it 
possible for me to repair this filesystem, or am I SOL? The installation had 
some nice information (bookmarks, history, special software installations) 
and I would like to recover it if I can. Anyone?
