At home I use a Mac Plus with a MacConnection 20Meg drive manufactured by
Rodime.  A few days ago I wanted to use the drive and its data at work for
a demonstration we were giving, on a standard Mac II.  The dreaded "Disk
Unreadable -- Initialize?" dialog appeared, with the correct icon for my
drive.  As far as I can tell from the manuals for the drive, the installer
is specific to the Mac Plus, meaning that the interleave for the drive is
probably 1:3.  I had been under the impression that while 1:1 drives were
too quick for a Plus, slower interleaves were usable but less than optimal
for the II.  This appears not to be the case.  Is there any way that the
same hard drive could be used both on a Plus and a II without reformatting?

Thanks in advance for your advice.
