Hi Jon,

So it looks like Amanda can't find the volume even though I know this volume 
did exist.

Here's the messages I received from 'amrecover':
Volume labeled 'PCBI38L4' not found.
Load tape PCBI38L4 now
Continue [?/Y/n/d]? Y
Not an amanda tape: Can't open tape device chg-zd-mtx: No such file or directory

Got no header and data from server, check in amidxtaped.*.debug and 
amandad.*.debug files on server

I also see this in the log file 
(/var/log/amanda/server/Daily1/amidxtaped.20111124183504.debug):
[...]
1322177849.880209: amidxtaped: changer: << 39 tape:/dev/nst0
1322177856.739641: amidxtaped: Device /dev/nst0 error = 'No tapestart header -- 
unlabeled device?'
1322177856.739710: amidxtaped: Device /dev/nst0 setting status flag(s): 
DEVICE_STATUS_VOLUME_UNLABELED
amidxtaped: slot 39: Error reading tape label:
amidxtaped: slot 39: No tapestart header -- unlabeled device?
[...]

Is it an indication that the label got corrupted on the tape in slot 39 (tape 
label 'AHE948L4', volume label 'PCBI38L4')? This tape was definitely labeled 
and used by the backup I need to do a restore from.

Note that that this is the same tape I got a tar error. What is the correct way 
to restore the label on the tape (if it got corrupted) without losing the 
contents? Is there a way to retrieve the contents from a bad tape manually?

Best,
Valeriu
