Well, a short test of my DTLA-307045 on the VIA chip was ok with msdos
and ext2fs (ext3 actually, but who cares for read-only), but if the
implementation in the drive has changed, I'm interested to see what will
happen soon, as I expect more drives to support tagged queueing now that
it's been in the ATA drafts for some time.
