Well, i had the same problem over here..
Nowadays it works, but sometimes it doesn't find the hd's when booting up.
In my case it's for 90% sure it's the 2.5" cable connector to the computer that isn't perfectly tight.
However i have an C64-motherboard also inside my homemade midi-tower, so i can't really get my fingers inside the machine to try to correct it atm. (Also the Melody 1200, and the Elbox IDE-thingy is in the way) :-D
Does it work if you just boot with no startup-sequence, just to see if it's not software related?
Do you have another hd-cable to try?
