- What exactly is "downloaded a hard drive to a new computer'? It sounds like something you shouldn't do.
- What exactly is "not recognise"?
- So you didn't do it the way Apple tells in https://support.apple.com/en-us/HT204318 ? Why not?
Obviously, whoever did what he did, didn't do this very well. Time to go back and let them fix it. Youd didn't pay for half work, did you?

I recently got a new computer and had my hard drive downloaded to new computer. Now itunes will not recognize my ipods. Have reinstalled itunes most current version.
