I upgraded my unit and I have a question. I get a lot of W's showing up in the upper right hand corner, as well as a hard drive with a solid grey box through it. When I go over bumpy roads, my Empeg complains and freezes, and if I pull it ouf of the dock and put it back in, it sometimes says hard drive not found - system error.

I'm guessing I did something wrong with the installation. Hopefully nothing permanent.

Unit seems to work fine when it's plugged into the wall and on a table, but I do still see W's, which I never saw with one drive.

Guessing this is a HD error or installation errof of some kind. Any ideas on how to deduce?
