    • It's likely that there is a cable clip holding the ribbon cable to the case.

    • To remove it, push the end, and it should pop up.

    • With the clip free, pull on this tab, lift the cage up, until it clicks, and pull it away.

    • Now, set the cage on top of the CPU, and remove the power connectors.

    • Once the cables are free, set the drive cage aside.

    • To remove the hard drives from the cages, remove the four screws on the sides of the cage that are connected to the drives, than slide the drives out.

    • The two cages are cross compatible and can be put in either rack.

    • The MDD does not have a 128GB drive limit like older macs, My MDD has 3 Drives (A 400GB Hitatchi Deskstar, 40GB Seagate Baracuda 7200.7, and a 30GB Quantum Fireball LCT).

    • Note the ID jumpers on the two drive set. One is set to Master, the other to slave. A single drive can be set to Cable Select.

    Thanks - excellent tutorial!

    Question: If you have a single internal drive, and a connected extrenal drive via firewire or usb, what jumper setting should be set for the internal drive and the external drive? Booting into Mac OS 9 natively (not via Classic) on the internal drive seems to be sensitive to the jumper settings and I’m having issues getting it to work.

    I ran my MDD with 3-750GB IDE HD’s. When they got flakey I replaced them with 2TB SATA drives in the back cage with a cheap SATA to PATA adapter and they formatted out to 1.8TB. I then cloned (CCC) the boot drive to one of the 1.8TB drives. It boots to the new drive and every thing seems to operate like normal. I don’t know how big we can go but we know that a MDD will handle at least 2TB HD’s and I have 5TB in my iMac 15,1
