Bug#11922: I/O error on blank tapes

[Stephen Kitt <steve@sk2.org>]

Hi,

This does still occur with 2.6.22; with a blank tape in my HP DDS-4 drive:

$ tar tzvf /dev/nst0
tar: /dev/nst0: Cannot read: Input/output error
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now

gzip: stdin: unexpected end of file
tar: Child returned status 2
tar: Error exit delayed from previous errors

Nothing gets logged anywhere, which fits the original bug description.

This is a well-known issue: see for example
http://www.sibbald.com/bacula/html-manual/Bacula_Console.html (search for
"blank tape").

Regards,

Stephen
