Drive is sold as is due to age. I took this apart, cleaned and lubed and tested it on a Macintosh SE FDHD. The three system disks are included. System 1.1, System 2.0 and System 3.3. The system disks were formatted and written to on this exact drive. The Macintosh was then booted from the external drive with all three system disks. Eject motor works. This is a 400k drive. Bonus, the system 1.1 disk is in French. I have a couple of these for sale on different listings. You will receive the exact one pictured if you buy. Please don’t hesitate to contact me if you have any questions. #4
