Michael, thanks for the info - I was unaware of that. But there still
seems to be the issue of why formatting the disk using the System
Utilities "fixed" the problem. This would imply that the System
Utilities is formatting the disk differently than ADTPro would it not?

If no one else is having this problem then maybe it is something to do
with the Superdrive. And I thought I was lucky having one of these
drives.  :-)

I also have a ROM01 IIgs with a regular 3.5" drive attached that I can
also test. I'll perform some more testing tonight and post back with
results.

cheers,
