Since ILPer 2.0 there have been two mass storage emulations. HDRIVE1 is a high-capacity emulation with a default configuration of 16MB. Perhaps larger than the 41 can handle. Try using the HP9114B emulation.

I think it's more basic than that and at the same time more tricky.

The difficulty is the way the HP-41 is managing multiple mass storage units. When writing a file, the HP41 will scan ALL mass storage units to find if the file already exists. And if one of the units has no disc, you will get a NO MEDM error, even if the operation was targeting an other unit. See the HP-IL manual the section "Using Multiple Mass Storage Devices" (page 39 english edition)
Solution: initialize (NEWM) the 2nd unit disk.
