Do you get this as soon as you plug it in?
More details would be helpful...
Do you have a second Mac available that you could try plugging it into? It might be a problem with your iTunes software and not the iPod itself...
Anyone help with an unknown error (-48) ?? Please - 5th Gen ipod.![]()
Same issue here.
Tried it on a different machine and I have tried the 5 R's but the issue still exists.
This has only just started since the recent iTunes update, so hopefully a fix will come out soon.
I was having this problem too (5th gen iPod also), after several hours of searching the net i found this bizarre fix from apple support.
I had nothing to lose so, I gave it a go...and to my astonishment it actually worked! I didn't even follow the instructions fully, I simply changed the time zone and tried syncing without doing the restore and it worked. I've since changed my time zone back and disconnected/reconnected my iPod a few times and it's syncing just fine.
