Although my drive came with a different setting when I got it, I found that an ST-251 drive works fine with the same setting you highlighted (Rev. C, settings EFCD).

The ST-251 drive itself can be formatted to hold over 40MB, but when installed as described here, it is only seen as 15MB of storage.

Other drives can and do work, but since 15MB is likely more than enough (at least for Series-80 with the flat file structure) I recommend the ST-251 since they are still fairly available, and tend to be quite reliable. Most of all, they're cheap, I got mine for $28.
Thanks! I do have quite a few ST-251's lying around, so will definitely try one. Agree 15MB is more than enough. And it'll sound pretty cool, few drives have that iconic 251 startup sound. Smile

Noob question; how does one do a low-level format on it? I assume formatting from DOS on the 150 expects the disk to have already been low-level formatted?

If you can connect it to a machine running MS-DOS, you can run debug and enter

G=C800:5

The low-level format program is built-in.
