Well I can confirm my previous answer to question 1) - I re-did the test
using a fresh disk and the disk was reported as <I/O ERROR> with 1600
blocks before the format, and "BLANK" with 280 blocks after the format.
So it is looking quite possible that it is the Superdrive causing problems.


The format code I borrowed sends a SmartPort format request to do the
low-level media formatting, and I suspect that's working fine.  I then
grab the device characteristics (specifically, the block count) as
displayed and use that to write the block bitmap on the newly
formatted image.  So it's definitely my fault for writing the wrong
bitmap, but there's some peculiarity going on with the drive.  Do the
slot/drive numbers change any before and after, by chance?

Also... what's the model number of a Superdrive?  I see from this
page:
http://www.vintagemacworld.com/drives.html
that there's a "Superdrive controller," but none of the drives
(Unidisk 3.5", Apple 3.5" external, etc.) are actually named
"Superdrive."  Which one is yours?


The "Apple FDHD External (G7287)" is a Superdrive.  Early ones
had "FDHD" on the front, but later models dropped that and
branded it a "Superdrive" on the label underneath.

Frankly, Apple has reused "superdrive" so many times and for so
many different things that the term should probably be retired.
The only thing it's better than is "FDHD"!  ;-)
