I get this error on startup, and options to either reset or exit the screen. If I exit, I can call up registrations but only the instruments are available, not my drum patterns.

Any ideas what the problem might be? If I knew where the hard drive was located I'd turn off the machine and check the connections to the hard drive but the manual (pdf) has no troubleshooting section.

Thanks for any help... this is my backup unit, but I'm gigging this Saturday!
