ok, the most peculiar thing...
i start my car w/ the empeg in the bay... it starts to play a song, and after 5 seconds, sputters then stops. i say wtf, so i pull it out and put it back in.... it gives me a "no hd found, contact support" screen. then i pull it out, wait 5 minutes, put it back in, and switch songs as soon as i can. it then plays the next 2 songs properly.....

on the 3rd song.... it plays the song... and then a part of it gets garbled, then goes back to normal.. i rewind it to the same part, and its plays back ok now... 20 seconds later, the same thing....

is it time to email david for support?

either the cable or the drive going bad. mine did that because one the the drives didn't have spacers under it.

i left it overnight to run.... and attached a serial cable to log what happens... heres what it did.

If it is a Rio-branded player, then it is most likely just a bad cable.
