Power HP Tape Driver "Unknown Density"
Dear Experts and Advanced User,

I encounter a rare problem as mentioned above. I am not able to read the tape cartridge using the following command:

#dd if=/dev/rmt/0mnb ibs=16k | tar tvf -

It will prompt me with the message saying DD I/O error, broken pipe; everytime the above command is enter.

However, it still support

#mt offl
#mt rew

By using sam, under the tape drive section, the physical hardware is listed. But, when I go to device files, it shown as following:

/dev/rmt/0mb berkeley unkown density "TYPE_DEPENDENT1"

/dev/rmt/0mnb berkeley no rewind unkown density "TYPE_DEPENDENT"

The tape drive and tape cartridge BOTH are in good condition. Both items can be use in different machine with the same OS.

Appreciate if anyone could provide me some solution or useful tips?

Thank you
