Samsung SFD-321B 3.5″ floppy drive and specifications

I plan to create a separate section for these type of documents, but I wanted to get this online for now.

I purchased the Samsung (made by SEMA, the division split off of Samsung that mostly makes floppy drives) SFD-321B 3.5″ PC floppy drive that I’m using with my project. While I have other similar documents, this one specifically covers this model of drive, and getting a hold of this type of documentation on new commodity type items can be pretty hard sometimes.

The newegg link to the drive is here.

They were happy enough to send me THIS PDF SPEC which includes pinouts, mechanical drawings, timing diagrams, etc. Very useful. Not as good spec’s as I’ve seen, but very good.
