I'm as little confused here, didn't you just say that the SSD worked as 
it should ? Please clarify.

Or do the mSATA SSD disappear when you plug in the Fujitsu Hard Disk ?

I have long time ago turned up for a powerup mS delay, I think we need 
seconds now....

It's the first SATA disk I have seen with that problem, the net6501 has 
so many expansion options it's probably the right time to add a delay 
option in the comBIOS, I'm already considering it as we also have the 
powerup timing issue with some USB devices.
