Emax

hi - i hadn't fired up my emax II rack HD in about 5 years but yesterday all was fine until i briefly shut it down to rearrange it in my rack ..... when restarting, the internal HD started to spin but after about 10 seconds powered down.  msg on the display: checking floppy drive, checking scsi I ...... then goes into a checking scsi 2,3,4,5,6,7 loop ad infinitum.  floppy light is on as is the tiny red light to the right of the sequencer stop button.  anyway, that's all i can get it to do at this point.  any help would be appreciated!  thanks!
