D’oh, my previous reply didn’t come thrue (see below) - accidently tried to send it from my other email account and the list didn’t accept it. 

Anyway, thanks and a small update:

I have now tested and my 2031 can read a 1541-formatted disk (from another drive) just fine.

d64copy won’t work (drive led starts blinking as if it has an error condition, but as I quit d64copy, it resets the bus and I can’t see the error). cbmctrl doesn’t seem to like the 2031 too much; it doesn’t recognise it (cbmctrl detect -> 8: *unknown*, footprint=<DBDC>) and often it just halts (fe. trying ”cbmctrl dir 8” couple of times, at some point it just does nothing (goes back to prompt) or replies "73,cbm dos v2.6 2031,00,00” repeatedly. Sometimes I need to replug the Zoomfloppy to restore normal operation.

The head looks pristine and I am using a NOS (non-formatted) double density disk (none of the previous ones from the same box have failed me). There was a bit of sticky residue on the drive belt and it wasn’t as flexible as it might have been, could be a problem. While spinning it does sound a bit noisy (compared to my other IEEE-488 drives).
