1) I would suggest you discuss with AJ about retaining your original disk. (personally I feel all owners should retain their original drives)

2) The hard drive you are using as a clone is not compatible with the Audya (hence the LED is on). You should not use this hard drive in your Audya.

You should also discuss with AJ about the ramifications of moving back to the the original content. It may not be possible without some work.
