Funny, I have an HP C1533A DAT tape drive also.  I'm not at home right
now, but I could swear that my DAT drive negotiates synchronous data
transfers at 5.0MB/sec.  I'm using a 2940W and definitely have synch
enabled in Adaptec BIOS.

I'm running 2.0.5R.

I've never had a problem with my tape drive with synch enabled.  I've
also run some pretty intensive tests on my two hard drives, CD-ROM,
and the DAT drive without problems.
