FYI (or others using retro equipment with floppy disks) there's a cheap floppy disk emulator called Gotek that can be connected in place of your 3.5" drive and has an USB connector where you can put a thumb drive with disk images.
For that device there's an Open Source firmware project called FlashFloppy [0] that enhances its features. And I've found today that there's an Open Hardware reimplementation [1] of the Gotek hardware that's compatible with the FlashFloppy Firmware.
