    I am really just trying to get the disk cloned so I can safely run Disk Warrior on the original. It has been crashing FCP X repeatedly in one project, all signs pointing toward a corrupted sector.

    Rich, please note that there are some known issues with G-Drives and Carbon Copy Cloner. I don't know how relevant these issues may be to your case, but it might be worth your while to head on over to the CCC website and ask Mike Bombich directly about your problem. Here's a discussion about the G-Drive issues.

    It sounds like what mine does, and as the same behavior has occurred in both CCC and Disk Utility, I expect that is what is going on. About 1 hour into the 4th attempt. Should be soon before it hangs again.  Thanks for that link good information.

    One thing I have noticed is that when you Daisy Chain FW-800 drives, if they are bus powered, they tend to have more disconnects, as for some reason the bus doesn't always provide sufficient power.  This tends to happen when working with large data transfers to drives which require more power (like a 7200RPM drive).  If your new drive has an option to provide external power, or can be connected directly to your Mac (without any daisy chaining), then do that and see if it helps.  Another thing to consider is that if it is FW-800 attached, you might want to consider trying a different cable.  I use a FW-800 drive for my iTunes Library, and I've found that after a few hundred connect/disconnect sequences, that my drive will start to have this problem.  If I replace the cable with a new one, then the problem goes away for a few hundred more cycles.  The FW-800 cables just don't seem to handle being plugged/un-plugged a lot...

    Thanks, this does help alot, all this good info. Right now, the new one, which does have a power supply, is connected directly to the laptop. The one being cloned does have a power supply. I am going to get the power supply for the mini G Drive. It has not been about 3 hours, with 6 more to go. Fingers crossed.

    Ok, I am at a total loss now. I spent the entire day cloning, finally was able to get that to work. So, brand new disk, checked out by Disk Warrior, same behavior. Gets stuck while rendering, and will not respond to anything. I have to hard reboot the laptop, remount the externa drive and try again. Renders for a few seconds, then sticks. Is this my laptop?  thanks again.

    If DiskWarrior hangs it sounds like the disk is bad. Get a replacement for it.

    ...or maybe it's just that G-Drives don't play nice no matter what you do. Rich- if you do replace the drive, replace it with something other than G-Drive (and the same goes for Western Digital - with which there are also issues when it comes to cloning - see the CCC discussion forums).
