[comp.sys.mac] apple 1.4M drives

IRWIN@pucc.Princeton.EDU (Irwin Tillman) (01/06/89)

Does anyone know if Apple's 1.4M drive really works with 800K and
400K Mac disks "as advertised"?

If you recall, although Apple 800K drives "work" with 400K disks,
writing on a 400K startup disk in an 800K drive can sometimes alter the
data so that the disk can no longer be used to boot a Mac.
(This isn't widely "advertised.")

Does anyone know *for sure* whether the same problem has been
found on the 1.4M drives, or do they "really" work?
