emm labs cdsa cd stuck in transport

Unplug wait a few minutes and plug back in, may work, may not. Worth a try though.

I had a problem like this twice with mine (though I didn't hear the mechanism engaging, just seemed to be frozen), had to ultimately send it back to EMM each time, but the last time they said there would be no further parts for the repair.  You might try turning the unit off and then on again, maybe a reboot will get it working, as your problem sounds like it could be different than mine.

Try taking the top cover of the chassis off and access the drive from inside. Snook you can always call me if you would like.

Sent the cdsa back to emmlabs. They still have parts to fix it.

Good to hear.
