The original 800K Apple diskette drives had one switch to detect whether the disk-lock window was open or closed.
The 1.4MB FDHD or "SuperDrives" had two switches, one for the disk-lock-detect, and one to detect HD diskettes (the "extra hole"). In fact, the presence of the two little switches at the front of the drive is the easiest way to determine if it's a 1.4MB drive. ----- Original Message ----- From: "Matthew Wheeler" <[email protected]> To: <[email protected]> Sent: Tuesday, February 10, 2009 11:18 PM Subject: Re: 800k 3.5" disk drive for PowerMac 7100 > The switch that was mentioned earlier was not an HD switch, but a disk lock. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
