It's seems that onstream sc30 tape drive is not a good choice for FreeBSD.
So, onstream adr30 should work well. I'm not sure I will use this one. dds
or dat
is maybe a better solution.
Does anyone know good tape drive (native capacity 15-25 gig) for FreeBSD.
I couldn't find anything related to ?ETRIXC? on the web.
So if anyone have a suggestion, I'm interested.
