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.

I run my Cirrus drive on both my Plus and a IIx. The drive is formatted for the Plus's best performance, I figure it needs as much help as possible. Try to get newer formatting software, or the shareware (pay-with-your- blood) driver that Vishniac (sp?) wrote, or one of the commercial packages (like the SilverLining the comes with Cirrus drives). Do worry about other software incompatibilities. Booting off a disk which has Autoblack installed will give a II coniptions, for example. If you run with a zillion INITs you must consider a zillion things which can go wrong (I do, I have). If you persist you will be able to get this to work--but first: Backup Your Disk. You are heading into dangerious waters about now. Kent Borg kent@lloyd.uucp or ...!hscfvax!lloyd!kent
