I hooked up two Macs through a firewire cable and the booted through the Leopard Install disk and used Disk Utility's restore feature. It took about two hours to move 90GB and the block-level clone was perfect. CCC gave me so many problems, and I can't boot into anything to clone the drive or image using it, I'm always going to use the free (and no advertisements) built-in Disk Utility.
I didn't want to use Time Machine because I really do think of using it only in emergencies, especially because I knew it would be slower, especially over wireless.
What sort of conflict? If the computer says "park" and the drive is already parked, what's the drive gonna do, unpark itself? SMS in the drive firmware is extra insurance against Apple firmware issues. I suspect Apple hasn't done extensive testing against race conditions in high-G situations. I say this as someone who's lost weeks of productivity to gravity.
If you know of bugs I'm very interested, but I'm not seeing the failure mode based on your post.
Haha, I wish computers had as much common sense as most people, but a google search shows me some people earlier this year having problems, though probably on an individual drive basis.
As I imagine it, if the computer is running, the sudden motion sensor in high centrifugal force situations, it should lock up your drive and not let it go--I wouldn't let go of the steering wheel in conditions like that either though
From what I've read on the drive I do have (without SMS), it has features that protect the drive head while off, if your computer's gonna be riding while off in the back seat:
"Reliable and rugged
* WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
* WD's SecurePark parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear and improved shock tolerance. "
