I have been trying to connect an 800K Sony floppy disk drive up to the external drive port of a Mac Plus. When I turn on the computer the disk drive immediately begins to infinitely cycle through its eject sequence. Has anyone else seen this problem? And of course, does anyone know what the problem might be? Thanks, Rich Simoni simoni@strat.stanford.edu

This happened to me once, too. I had a hard disk, and I got it to mount off the hard disk instead of a floppy by holding down the mouse button for a while (which forced the drive to try to mount the non-existent disk a little harder, I think -- it wouldn't try to eject as often) and then letting up on the mouse button. However, this wasn't a solution, just a way around the problem. Once I got booted up off my hard disk, it still thought that there was a floppy disk in the drive, and told me that it wasn't a Mac disk. I had to insert a disk to get any work done. In addition, doing work off the hard drive took somewhat longer than usual, and doing work of the floppy disk was, essentailly, impossible. I took my Mac to the Apple technician where I worked. He fixed it for me (of course, since we were an authorized Apple repair place, he had to give me a new drive, which cost something like $140). If these are your symptoms, you have my pity.... -- R David Francis francis@cis.ohio-state.edu

It's happened with 6.0.3, .4, and .5. I haven't the foggiest idea what's causing it, but sticking a floppy in the drive will usually cure the problem.

We had a problem similar to this once too. One of the macs out in the lab wouldn't take a disk in the external drive to boot up off of. I put it in the internal drive, and it still wouldn't take the disk. I tried another disk. Same deal. I thought it was really serious until someone noticed that the mouse button was stuck down. Sometimes the answers to problems can be really dumb. Hopefully your problem is equally silly.

When I turn on the computer the disk >drive immediately begins to infinitely cycle through its eject sequence. Disclaimer: I work for Apple, but my job has nothing to do with disk drive hardware. I discovered this information empirically prior to my employment at Apple, in the process of getting an 800K drive to work on a Lisa. I believe that later revisions of the 800K drive (not sure about 1.4M drives) use one of the signal lines of the 20 conductor ribbon cable as a dedicated eject line (probably for use in the UniDisk 3.5). That line was formerly used as one of the power or ground lines. Unfortunately, I'm not sure which line it is. Anyhow, if you cut that line the drive might work correctly (it solved the problem for me). If you look at the ribbon cable Apple supplies with internal drives, that particular conductor is MISSING. Just insulation, no copper. Eric Smith esmith@apple.com Opinions expressed herein are not necessarily those of my employer, family, friends, computer, or even me! :-)
