My SE/30 using 7.5 knows how to format double sided disks for HFS - well the last time I actually did it was a decade ago and it's possible that I changed the disk drive sometime before that. In general it's never a good idea to plug that second hole though. It's there to indicate the type of magnetic surface that the disk is made with. The official high density two sided disks require a higher magnetizing field than the single sided jobs and the drive needs to know that. If you tell the drive to treat a double sided disk as an older single side device it may wind up with its bits not fully saturated and subject to failure. But it's worth a try to see if the SE/30 really has a single sided drive in it. -- --> Halloween == Oct 31 == Dec 25 == Christmas <-- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of the Vintage Macs group.
