George, that will not work. An unmodified Cube's internal controller can't address more than 128gb. It doesn't matter if the drive is partitioned; the Cube can use only the "first" 128gb. Pick up a nice 120gb drive. They're inexpensive, easy to swap in, and are basically the highest capacity the Cube can address internally. If you need more storage, you can get a much larger external drive; FireWire-400 is fairly inexpensive and quite fast. Remember that the Cube's USB subsystem is USB 1.1, which is fine for many purposes but not for mass storage. The only way to recover data from your cooked drive is to pay thousands of dollars to a professional data recovery laboratory *and* get lucky. Only you can decide if your data is worth the expense. Hopefully you have a recent backup of your data.
