Regarding using the drive as an internal unit, I believe you'll need a new Disk Drive Adapter to see the full drive size, however they are not expensive. I had a similar problem till I upgraded. It was a while ago and I cant remember the details of which adapter I bought. On using external drive cases, I've had mixed success, but I recommend companies like transintl.com dvwarehouse, and macsales. They know their stuff and their support is pretty good.

Now I am in the process of learning and changing from IDE to serial ATA hard drives. I bought a Maxtor DiamondMax Plus 9 200G SATA/150 drive. I have since then tried to adapt that new drive to my old IDE Macs. I have little doubt it will slip directly into a G5, but I don't have one (someday I will). Here is the source of my trouble. I have bought two adapters which plug into the SATA drive and allow my IDE cable to plug into the adapter. If I install it into my G4 the bus only sees 128 G. That not so good. If I install it into and external enclosure with both USB2 and Firewire, I have mixed results. Enclosures have different versions of hardware to support the drive and adapt it to USB or Firewire,\. The older versions work just like the G4. (Firewire works fine but 128 G) (USB1 (ugh) works but 128 G) The new enclosure (Addonics Model AE5SACSUF) with the Addonics SATA to IDE adapter works fine on USB2 but does not work at all on the Firewire port. Hook up to firewire, Disk Utility sees the entire drive (~200 G) but when you erase or partition the process hangs. Does anyone else have any good advice to help me resolve these problems? Maybe this is just a Maxtor problem, I don't know. Maybe this is just a warning to let you know that all the bugs have not been worked in the interfaces that support the SATA drives.
