My empeg is not playing.

This was a two drive unit 10 gig and 20 gig. For some reason now the unit will not boot up with the 20 gig installed, so i took the 20 gig drive out. Now when i boot up everything boots fine, everything in hyperterminal looks fine but none of my songs play. The time just stays at 0:00 , even when i hit play it just stays there.
I can access all the other menu items, switch to other songs and all but it doesn't play them.

Also rio emplode does not detect the drive, however i can apply upgrades and such.

Player also freezes while tryin to load playlist.

Ive tried reformatting using the builder image, but it says drive already contains builder image.
