Hi all,
i find it obvious that translation is done within the drive.
The reason: i've got an (older) ST-1144A which is a zone-bit recording
device. I.e., the bit density isn't constant across the cylinder number,
there are several sector counts on the disk. As far as i know, nobody
(except the disk manufactuerer) would be about translating everything
itself on such a drive. I actually don't know what this drive claims to
have as physical geometry (i'll test the program posted here...), but
seems to me that 386bsd driver is working (with patchkit applied).
Actually, this is a DOS drive in my computer, but at least, i'm able
to hexdump something from it.
