I have been trying out the OnStream DI-30 in STABLE which come up as
ast0: TAPE <OnStream DI-30> at ata1-master using WDMA2

Dump seems to work with it OK in that I can dump a file system and restore 
it OK. But tar does not. I have tried plan old tar and tar with block size 
specifications, but no dice.

ruby2# tar -b 4096 -c -f /dev/nrast0 altq-3.0
tar: can't write to /dev/nrast0 : Input/output error

It just gives a series of
ast0: bad request, must be multiple of 32768
ast0: bad request, must be multiple of 32768
ast0: bad request, must be multiple of 32768
ast0: bad request, must be multiple of 32768
ast0: bad request, must be multiple of 32768
ast0: bad request, must be multiple of 32768

no matter what block size I try.

The other quirk I noticed is that after a dump,
ast0: WEOF - ILLEGAL REQUEST asc=24 ascq=00 error=04

Is this just a limitation of the hardware and driver ? It looks like they 
have LINUX support on their web page. Too bad they are not doing the same 
for FreeBSD.
