This phenomenon annoys enough people that it's worth while repeating: nearly
any disk formatted on an ST will be handled properly by a PS/2 if the first
3 bytes of the 'boot sector' are made (3 bytes in hex to follow) EB 34 90.
I've done this for years with no problems. The reverse process, formatting on
the PS/2 and using on both machines, suffers from the famous problem that IBM
machines don't put unique serial numbers on each disk. Yeah, CHKDSK recognizes
that there's something funny about the disk, and some compatibles won't take
them, but for ST - PS/2 exchange, this is enough.
