Whoa !
That's a long time, but I'm glad you were able to get it backed up.

The drive I cloned was internal in a MacPro so it was SATA.
Possibly the USB speed was the reason it took so long.

I've been using CCC for years, the first time it saved by bacon, I quickly made a donation to the guy who wrote it.
It really is a handy program.

Sorry if I misled you on the estimated time, it was just a guess on my part, but I'm glad you got it sorted.
