Sorry for that, but I think that your Miniscribe is nearly dead because the formatter throws a lot of errors.
It's a miniscribe. Wad'dya expect? :p

I think with stepper drives you have to specify an interleave and low level format it..
For MFM and RLL interface drives yes but it's much less common for LLF commands to work on stepper drives with IDE/SCSI interfaces due to the higher level translating logic required.

In theory you can slap on a regular 8425's control board and LLF with that but the geometry will change when you swap back to the SCSI interfaced board.

This is why in the MFM/RLL/ESDI world if you formatted a drive with one controller card, you're stuck with the controller forever if you want to read the data back. Plug it into another controller and there's no promise the drive will be useable until after you format it.
