Hmm.... That is a good sign. It is seeing the hard drive as part of its system test. Is there anything that you do not have backed up? I would guess that perhaps you damaged something in the database rather than the hardware itself, and an upgrade with the latest firmware with format might correct the problem.

When you power on the unit normally, what exactly happens? Do you see the Rio logo and status messages on the bottom line? If so, can you tell me what status messages appear.
