What causes this to hang? I have tried it on several systems and tried a couple external drives. Below is the log file from one operation. You can see where it jumps from 03:16:14 PM to 03:35:13 PM after copying Chrismas Hits 60 CD2. Chrismas Hits 60 CD2 is only about 100MB but DV File is 4GB or so.
After much head scratching, hair pulling, and fist pounding, I discovered the following tonight. This may or may not help, but it can't hurt.

Scenario:
Intel 20" Core Duo iMac
Two External firewire drives. One is a Lacie 160GB, the other, a 250GB Samsung PATA drive in a Mad Dog Multimedia Firewire/USB enclosure.

SuperDuper! works flawlessly with the Lacie, but the Samsung "falls asleep" during the copying process. During this time, there is no progress displayed in SuperDuper!, and the drive is completely silent with the exception of what sounds like one "burst" of activity about every 2 minutes. The copy never finishes.
Tried CCC, same results.

Had an iRock (generic) firewire enclosure being used elsewhere. Swapped the Samsung drive into it, and behold, no problems whatever.

Here's where it gets interesting. Both drive enclosures are close cousins. The Mad Dog has a fancy illuminated front activity light, the generic iRock does not. They both show as an initio (If I recall correctly) interface in Disk Utility, so I'm guessing the chipset is similar, if not the same. The PCB inside both enclosures is very similar.

The Mad Dog enclosure works fine on my PPC Mac Mini. The iRock generic on either. So, I have concluded that there's something about the compatibility between the Mad Dog enclosure, it's firewire interface, and the Intel Core Duo iMac.
