i want to copy everything from my old mac to an external drive before i wipe the drive and give the old computer to someone. (I already was able to use Migration Tool to get the old files onto the new MB Pro, this is just a precaution.) So far nothing has worked. I've tried rsyncx, psyncx, carbon copy cloner, and all fail for different reasons. i decided to try cp, but it hung after 20GB of data; the total in my /Users/ folder is about 40GB. any idea how to figure this out? thanks.
