[Coco] Weird SDC Issue

[Ed Orbea]

By default (via startup.cfg) I auto-mount SCDX.DSK disk into drive 0

Sporadically, when not using the SCDX program (rather from the READY 
prompt) I try to mount another disk as drive 0 (ex: DRIVE 
0,"/HDBDOS.DSK"). The name is just an example.

When I then enter the DIR command, instead of the HDBDOS.DSK directory, 
the SDCX.DSK directory is displayed.

My MCU version is 120, and SDC-DOS version is 1.6

Has anybody else experienced this issue?
