Long Hang While Copying
 
When attempting to copy an external drive to a disk image (parse or read only) it seems SD hangs right away when it starts copying (info about how much has been copied stops increasing but elapsed time continues to go) and then continues once it gets to about 4GB or so. 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.

It doesn't really sound like it's hanging, it sounds like it's copying a large file. We don't update the status mid-file, so you won't get much feedback if something big is going across the wire...

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.

In general, non-Oxford bridge chipsets have a lot of trouble with OS X (it's not so much SuperDuper!, since we're not operating at the hardware level, but rather the FireWire kernel extension inside OSX itself).

These problems can manifest themselves in lots of annoying ways, including hung copies, failed boots, I/O errors, etc.

One of the differences between your two drives could be the firmware installed: it's possible that Initio has improved their compatibility in later releases.

But, if at all possible, get a drive with an Oxford chipset... in my experience, they work a lot better.

Thanks! I'm not sure it'll be easy to determine the chipset in advance of purchase (particularly when buying an enclosure only), but it's good information. Thanks again.
