I am using Linux Fedora 23 and I have a CentOS 7 also. I need to hook up a DAT72 drive to read old data from one of our old systems that I wan to take off line. At the moment it is flashing "Clean Tape", and I have some cleaning ordered.
SCSI 2 tape drive:
sudo mt -f /dev/st0 status
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
Bus 001 Device 003: ID 03f0:0125 Hewlett-Packard DAT72 Tape
