Hi,
we've got Sony SDT-9000 (DDS3) in a Debian potato box. So far, I've tried
only DDS3 tapes. It works this way:
- mt status always gives 0x13 (DDS) density code, any attempt to change it
produces errors. ignore it, forget it.
- the drive recognizes inserted medium automatically (holes in the
cassette) and uses the right format (DDS3 in my case)
- compression can be turned on and off
- with compression turned off and zeroes being put to tape in 64k blocks,
it took 11.5GB (that's exactly what they mean by 12G). The command was
'dd if=/dev/zero of=/dev/nst0 obs=64k', suggested by Kai Makisara.
- with compression on and *.mp3 stuff (=already compressed) in small
blocks (512b) it stopped after 9G were written, as compressing such a
data can actually make it bigger and small blocks didn't help either.
