The first card was originally formatted in my Mac. When I inserted it in my 9780 I was told that it needed reformatting. I did, and then I transferred my old data, and got the error message after several different attempts. The second was therefore formatted in the 9780 only.

With this new one I have now successfully gotten some music over without getting any error messages, but it seems as I'll have to move just a couple of albums at the time.

Is this really normal? If that is the case, I am seriously considering going down to 16 instead...
