Further information. I've run debugfs /dev/sdb1 which provided me with
full stats on the filesystem. I was able to navigate around the
filesystem and see the files that i thought i'd lost - good start i
thought. I also noticed that the needs_recovery flag was set.

When I ran e2fsck /dev/sdb1 the output was as follows:

e2fsck 1.32 (09-Nov-2002)
/dev/sdb1: recovering journal
/dev/sdb1: Attempt to read block from filesystem resulted in short
read while re
ading block 2072

JBD: Failed to read block at offset 1505
e2fsck: No such device or address while trying to re-open /dev/sdb1
e2fsck: io manager magic bad!

Could the problem be that the journal is corrupt? If so, how do i
remove it - bearing in mind the needs_recovery flag is set.

In the end there are about 20 files i need off the filesystem - is
there any way of copying them off using debugfs - if that can see the
filesystem why can't other things like mount?

Thanks again in advance,

Mario
