The D4 should be a 40/44MB drive.  The D2 was the 2nd generation 20MB drive.

Swapping the drive isn't really a problem.  Getting the drive to work w/ 
the Sider software is an entirely different issue.  Some the newer drives
(i.e. later drives: D4 and D9) were actually pure SCSI drives.  If the 
data cable inside your case connects all 50 wires to the 2x25 female 
connector, then the easiest thing to do would be to drop a SCSI drive in 
there and hook it up to a RAMFast SCSI controller.

This is a resistor pack (SCSI termination resistors).  CTS is the 
manufacturer.
