I have tried bulk erasing 1.44 MB disks and they still won't format in the HP9114A battery operated HP-IL Floppy Disk drive.

Having grown up with 1.44MB 3.5" floppies, I have a question: is it
possible to use a 1.44MB disk and just format it as a 720K disk?

I think it's entirely possible. I'd definitely format them in a 720kb drive though to be extra safe. Though original 720KB disks written/formattedĀ  in 1.44MB drives seem perfectly cromulent from my experience.

However don't quote me on it, The only double density drives i have are super early Sony ones built in 1982 and they get pampered with NOS 720kb media (with the sliders sellotaped open because no auto opening shutters on my drives!)
