Geek With Social Skills | Commodore PET 2031 Floppy Disk Drive Cleaning, Service & Testing Shugart model number 390 mechanism @geekwithsocialskills | Uploaded February 2020 | Updated October 2024, 41 minutes ago.
I picked up this Commodore 2031 floppy disk drive in a trade deal from a fellow retro computer enthusiast for use with my Commodore PET 2001 Series computer. It has an IEEE-488 interface bus and uses 5.25" floppy disks.

In this video I clean up the metal case inside and out, service the made in the USA Shugart Associates model number 390 disk drive mechanism by cleaning the read write head and drive rails, then do a smoke test. After that I connect up the drive to my Commodore PET 2001 computer and format a blank disk to make sure it can write to a floppy disk, and then load the directory.

Some of the back story about this CBM 2031 disk drive: My friend picked up this drive along with various other Commodore PET computer items from a school liquidation sale 15-20 years ago, then stored them in his outbuilding and until recently they haven't seen the light of day.

DISCLAIMER: Please do not take this video as a tutorial / advice. I'm not an expert, this is just my hobby :)
