[Bug-tar] Problems restoring from multi-volume DLT tape archive

[Leonard Sitongia]

Hello,

I'm testing writing a multi-volume Super DLT tape on Windows XP using 
Cygwin's tar and reading those tapes on Linux using tar there.  The 
writing seemed to go normally, and I was prompted for the second tape:

$ tar -c -M -b 128 -f /dev/nst0 g/20050421/
Prepare volume #2 for `/dev/nst0' and hit return:
(loaded 2nd tape and hit return)

When I was reading, the first tape read fine.  At the end of the tape, 
it simply finished, there was no prompt for the second tape:

# tar -xv -M -b 128 -f /dev/nst0
20050419/
20050419/20050419.111408.fts
20050419/20050419.111424.fts
...
20050420/20050420.180332.fts
20050420/20050420.180346.fts
(just ended here, didn't ask for another tape, so I loaded second tape)
address@hidden tape]# tar -xv -M -b 128 -f /dev/nst0
20050421/20050421.121910.fts
tar: 20050421/20050421.121910.fts: Cannot extract -- file is continued 
from another volume
20050421/20050421.121927.fts
...

I've read a few messages in the archive about multi-volume problems.  
Should this work, or is it a know problem?

Thanks for your help.
