these are my notes.
Format new tape with LTFS (tape not mounted yet):
mkltfs -d /dev/st0
Force reformat of existing LTFS volume:
mkltfs -f -d /dev/st0
the first time: mkdir /media/tape1
Only one process at the same time! Start only one write/read process.
Otherwise the tape drive behaves very slow.
1. umount /media/tape1
The umount command will return immediately, but the drive may still be busy
writing cached data to tape.=20
Do not attempt to remove the tape cartridge until all tape activity has
Check the front panel LEDs and wait for them to stop flashing.=20
2. =E2=80=9Eltfs =E2=80=93o eject=E2=80=9C or press eject button=20
installation guide (firmware update not needed with new LSI cards)
You can use Spycer version 3.x to enable "autoformat new tapes".
with kind regards
