Hi,

I have two DAT tapes that I try to erase. Trying to erase these tapes using
the mt -f /dev/nrst0 erase command produces (after a few minutes) the 
following error message:

   st0(ncr0:6:0): MEDIUM ERROR asc:3b,0 Sequential positioning error

Can someone explain what this message exactly means?

Both tapes are almost new; they have been used only once before.
The only time that the tapes have been used is for making a DOS backup 
using norton backup for windows. These backups have both failed.
I find it hard to believe that both new tapes have a been physical damaged.
So, I suspect a soft error on the tape is introduced by the failing of norton
backup. Is this possible?

I can understand why writing of the tape may be difficult, but I don't 
understand why erasing this tape fails. Can anyone help?

Regards,

             Frank
