I've got one of those installed already. It's a Teac FD-505. My, but
they're useful. I have a stash of them. Whenever I get in a PC that has
one I strip out the drive before heaving the rest. What brand/model is

Sweet! Dell has the documentation for these drives online:


The whole impetus behind this was that I was trying to read an old 360K
(might even be 320K or even 180K, I'm not sure) disk and while I could
read the directory, none of the files larger than say a cluster could be
read. I attributed this to the drive not being a "true" 360K drive.

Fred seems to be the Guru with regards to floppy formats, and perhaps I
misinterpreted what I read, but I recall him bringing up a scenario in
which a disk formatted as 360K on a newer drive would not be readable on
an "actual" (i.e older) 360K drive, or the other way around, or something.

I'm using an older 486 motherboard, and it works fine of course.
