Please do not respond to me about the following comments! You can reach him at "tanyelm@dupr.bitnet". His response follows: --------------------------cut here ------------------------------------- The high density disks are about 1.4 Mb (not 1.2 Mb). I use a IIx that has one of these "superdrives" and I can still use my single sided, 400K disks from years ago when the only Mac was the 128K. The HD disks should not be inserted into the 800K drives after they have been formatted for 1.4 Mb, the 800K drive will not recognise them and will come up with the standard dialogue box: "this is not a Macintosh disk, do you want to initialise it, etc." (just as the 400k drives did not recognise the 800k disks when that transition was taking place). However, I do not find the 1.4 Mb disks all that beneficial. I still use 800K disks whenever I need to back up data. I find the hard drive indispensable, though. The superdrive will format a HD disk for 1.4 Mb automatically, the user is given no options. When formatting a non-HD disk, the user is given the usual options: single sided or double sided.
