Hi Richard
Turn off the MD600 on the front panel.
LED on front panel switch turns to blue
Wait until LED on front panel is extinguished.
Turn off power switch on rear panel.
Now safe to remove one disc.

MD600 can now be rebooted with only one disc loaded
Turn on power on rear panel
LED on front panel is Blue for 2 to 3 seconds then off
Press switch on front panel and LED comes on Blue
After approx 10 seconds LED turns White and MD600 is running with only one disc.

No other LED 1 - 6 is showing on the front panel of MD600

I can now check using C15 as to the number of albums on the one disc in the MD600

As I have 2 MD600 units it is a little more complicated the other MD600 must be turned off first. (so only approx half of library is on line)

For 1 MD600 proceed by switching off on front panel LED turns blue
Wait until LED on front panel is extinguished.
Turn off power switch on rear panel
Replace the disc you removed
Remove the other disc and reboot as above

Use C15 again to check number of albums on second disc

Hopefully the numbers are the same.

Power down as above
Reinstate second disc
Power up as above

However there are risks in the process MD600 may go into restore mode with LED 4 and 5 flashing alternately. Why this should happen is way beyond my level of competency when nothing has changed as far as the data contained on the 2 discs in the MD600.

Just my practical observations

Comments welcome from IT experts
