Hi, I hope this is the appropriate forum for this email. I recently
booted into my linux machine and my /home partition (living on
/dev/hda8) failed to mount, subsequently I have tried reiserfsck with
most options and a newer linux kernel to no avail. See below for a log
of what I have tried and the output it generated.
Could anyone suggest any way in which I can retrieve some/all of my
files?
BTW, my file meta data retrieved by the command listed at the bottom of
this email is downloadable from:
http://www.deakin.edu.au/~ddp/meta_data_for_hda8.gz
root@pug:~$ mount -t reiserfs /dev/hda8 /mnt/restore/
mount: wrong fs type, bad option, bad superblock on /dev/hda8,
or too many mounted file systems
I am using linux-2.4.17 with patch-2.4.18-rc1.bz2 applied

**********************************************************
** This is an experimental version of reiserfsck, **
** !! MAKE A BACKUP FIRST !! **
** Don't run this program unless something is broken. **
** Some types of random FS damage can be recovered from **
** by this program, which basically throws away **
** the internal nodes of the tree and then reconstructs **
** them. This program is for use only by the desperate, **
** and is of only beta quality. If you are using the **
** latest reiserfsprogs and it fails please email **
** bug reports to [EMAIL PROTECTED] **

I read the reiser mailing lists and decided that maybe I had some bad blocks
on my disk, so I ran badblocks on /dev/hda8. Bad blocks did inform me there
were 3 bad blocks but the block numbers were WELL past the range it seemed
to be checking, but in case, I created a new partition of the same number
of blocks (as reported by fdisk) and dd_rescue'd /dev/hda8 to /dev/hda3
and went through all of the above with similar results
interestingly bad blocks seems to think there are bad blocks on /dev/hda3
as well but it is a fairly new disk, and /dev/hda3 was working fine under
win2000 when it was formatted as a vfat partition (it was nearly full as
well, so I am guessing the actual disk does not contain any badblocks):
[root@pug root]# badblocks -n -vv /dev/hda8
