Depends a bit on the controller but generally the answer is yes you can. 
You may run into problems if you try to put a more than 8GB disk on the 
controller. There are three things that older controllers suffer from:
         1) They use only SCSI 1 commands and are limited to
            drives of < 1GB
         2) They need to have drive locations "configured" before
            they recognize them.
         3) They don't understand removable media drives (ie CD-ROMS)

As the 4000/200 is fairly "new" generally #1 won't be a problem. You can 
avoid #2 by putting your new drive on as ID 0 like your current drive, 
however if you have a way to put two drives on to the SCSI chain try that 
and see if the controller "just works." The third one you won't know until 
you try to use a SCSI CD-ROM with the controller.

Merry Christmas to you as well,

P.S. The charge for help on this list is that you keep the chain alive by 
helping at least two other people. :-) This way one act of kindness can
