Before you try anything else, place a fresh disk (or one with no important 
data) in drive B: and use the PC utility DSKINI.EXE to format it

Then start the JV/JC emulator and see if the disk in drive B: can be read 
with a DIR3. If you still can't read the disk, then there is some BIOS or 
hardware issue on the PC. Post the results of this test.

If the disk could be read on the emulator, place the disk in a Coco drive 
and copy some files to it. Take it back to the PC and try to read it with 
the emulator.
