it will support ATI5 and I al looking forwards to that . . .
I'm curious about this statement. What exactly is needed to support a
new tape technology?
I would think that the SCSI tape command layer (SSC-3) would be
fairly sufficient to do most things (rewind, FF, toggle compression,
etc.). The only thing that maybe would need to be specified is the
block size and tape capacity for estimating usage patterns (though
use of compression would throw this out as how much you get is
determined by what you're backing up).
As long as the device is detected on the bus by the OS, and Networker
can access the /dev nodes, what needs to be done in the software?
