Al,
I don't think there is USB sticks with affs on them as yet. There
isn't even USB host controller support for Amiga hardware (yet).
Last I tried USB on m68k (Atari, 060 accelerator) the desktop
experience was such that I'd rather not repeat that in a hurry (and
that was a simple FAT USB stick)

No change in the weird behaviour of my SCSI-SATA adapter, but perhaps
that wasn't unexpected.

I'd like to think that, too - probably true for the Atari TT SCSI case
(can do scatter-gather, can do more than one command per LUN). Worse
for the Falcon SCSI which is the only one I can test (no
scatter-gather, one command per LUN, interrupt shared with IDE and IDE

could this be a partial write (target did not transfer the last byte)?
One would suppose the chip posts a phase mismatch in that case ...
