I know to pull the latch in back & have removed the 3 empty bay slots but cannot understand how to get the 1st slot to pull out. Is there a trick I'm missing? I think the s/n is 825-6913-A. There are torx screws on top but they don't appear to be holding the drive in place because I have loosened them (which is hard because there is no clearance with the top of the case which doesn't appear to be removable) so, the drive and I are both stuck! Trying to pull the drive for a recovery. Many Thanks!
