[Coco] Can't copy real floppy to CoCo-SDC on a CoCo 2

[mike at borncoco.com]

I removed the SDC and MPI and I'm having issues with accessing floppy drive 1. I may have some wonky jumper settings on one of these floppy drives. These are not RS drives & not identical. I'm not sure why that would cause things to behave this way, but this certainly needs to be addressed before I troubleshoot any further.

Cheers,

I'm having an issue with CoCo-SDC on a CoCo 2. I have an MPI (unmodified), with SDC in slot 1 and FD-501 Floppy in slot 4. It comes up SDC-DOS 1.2 CC2. I can mount drives and access things on the SD card just fine. However, if I issue the Drive command to access a real floppy, I loose access to the SDC and even the "DIR -" command returns an error as though SDC-DOS has vanished. I'm just trying to copy a real floppy to the SDC:
