I have a problem with a 400k external Apple drive. I can put a disk in and gently push it down to seat properly (drive obviously needs a clean), the drive will read the disk, and then eject. The disk still shows up on the desktop and I can load files (asks me to reinsert) and once the file is loaded the disk ejects again. Huh!?!?!?

I found it interesting - plugged into my SE, it detected I had put in a double sided disk and asked if I was sure I wanted to initialise it.

It always successfully ejects first time but sometimes keeps running the eject mechanism 5 times...
