How many hard drives does it take?

I've just had my third one in a year fail, but in fairness, the first two went back-to-back. I'm supposed to be able to copy my recovered data right to my new hard drive, but first it quit 0.1% in, then 60% in.  Now it looks as if I need to figure out where the process hung up and manually re-transfer the missing files.  Have I mentioned that I don't have time for this?
