I have 3 of the norco drive cages.  I recently got an 8T drive.  I precleared it in the middle cage and all was well.

After I set it as parity I wanted to move it to the upper cage that's connected to MB slot 0.  When I plugged it in, It wasn't recognized!!

I moved it to the far slot in that cage and it was recognized?

I plugged my old parity drive in back in the slot and it was recognized.

 

I've never had any sensitivity issues before.  Is there anything I look for?  I'd like to not have to worry about

one cage slot working better than another!

I Googled "the norco drive cages" and didn't get very far.  Could you give us a model number, so we might be able to give you some help?
