I just purchased a Maxtor 200 GB and an enclosure. I had another enclosure with a 120 GB. Both are Oxford chips. Both are 400 firewire.
I had the 120 setup as a bootable backup, and have no trouble with that working as it should. It shows up in Startup Manager, and can be selected and used as a stratup device.
Now, the 200 is another issue. I clone over a copy of my hard drive, and it does not show up in Startup Manager. It shows up in the Startup Disk Pane, but when I select it, it goes to the internal drive.
I switched enclosure cases, and the 120 still works, but the 200 still does not.
1. Repaired the 200 disk with DU and DW (no problems found).
2. Reset PRAM
3. Reset PRAM again
4. As I said, I switched the enclosures
5. Redid the clone with CCC
6. Firewire hooked directly to port on PB
Anyone got a helpful hint? Thanks.

Make sure that the drive is configured as the master via on-board jumpers
Look into the possibility of a newer firmware update for your FW enclosure.
How old is your FW enclsoure? I have some older ones with Oxford 911 and I remember that they needed a firmware update... what I can quite recall is if it was a size address issue or the drive's ability to copy without getting stuck periodically.

It was set to CS, and I changed it to Master. No difference.
New enclosure is brand new. Remember, when I switched the drives, everything worked in the new enclosure, just fine.

Which Partition Scheme are you using?
Apple Partition Map?

Try doing your clone with something other than CCC. SuperDuper is what I use and I switched to it from CCC when CCC stopped making bootable clones for me, even though they showed up in the Startup list of bootable drives.

Yes, straight out of Disk Utility. This is a no fuss clone, like ones I have done a hundred times. CCC has never failed me. Thanks.
