tape question

[Mark Szidik - Michigan Library Consortium]

I have a DAT tape from a library that claims there is data on it.  (data
put on it using proprietary library system running on HPUX).  I cant
seem to read it.   I have tried using dd and tar and even attempted
cpio, none of them can do anything with the tape.  This the second time
they tried to send me the tape, same result.  I think the tape is blank,
but I thought I would ask the group if they have any other methods to
try reading this tape.

Thanks,

-Mark
