DMS drive swap
This is a picture howto for opening your DMS to swap the drives out. This is a photo of a DMS cart:

Flip the DMS over and you should see four screws in the back side.
A regular phillips head screwdriver will work to remove the screws.
Take them out and keep them in a near by pile.

Once the screws are out, the back of the DMS should pull right off with ease.
You'll see the drive with the rubber surrounds and the interface adaptor to mate with the cradle and the phatbox.
There is a wide U shaped peice of metal and a larger plastic peice under that which is the eject mechanism for the DMS. These are not secured. Go ahead and take them and set them aside.
