20mb MFM drive. Had it on a 286 system. Had a 2400 baud modem that wouldn't hang up on it's own. Had to pull the phone cord when I was done dialing.
The most interesting drive I had though was a Maxtor 80mb drive. When it died it died wierdly. I couldn't get it to start until I put it into the freezer, then I got it to start so I could get my data off of it. Then I dropped it off my balcony on the third floor. Held up amazingly well for such a drop. Too bad it's internals weren't as well made as it's shell.
