There is a program called Apple Drive Setup SC or something to that effect which will format and prep 'apple' hard drives. (they rigged it so if the drive does not have an apple ROM it won't format it) but there are ways around that, check out: http://www.euronet.nl/users/ernstoud/scsi.html Neither the Mac 800k format is done with a variable speed drive and is practically impossible to emulate in software (PC users can get around this by adding a Copy II PC option Board which bypasses the drive's controller for better flexibility.) My suggestion is to see if you can get a set of SE Superdrive ROMs and a 1.4HD drive for your SE then you can use 1.44 meg disks which CAN be read on a PC (Via MacChette) and also can read PC disks on the Mac (Via Apple File Exchange). :) -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
