I need to admit that I'm quite discouraged. The new external case arrived
yesterday and I mounted the new hard drive (that worked for a few days in
the old case) and got everything set up. Still see the same errors:
[root at salmo ~]# ./dirvish-backup.sh &
[1] 27195
[root at salmo ~]# mount: wrong fs type, bad option, bad superblock on
/dev/sdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
cannot open config file: default.conf
cannot open config file: default.conf
cannot open config file: default.conf

When I try to mount it manually,
[root at salmo ~]# mount /media/hd0
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or helper program, or other error

This is a new case, new cables, new drive. What am I missing here? It's
been about 3 weeks with no daily backups and I really need to get this
working once again.
