(Get the code!)
I get the same on a Dell XPS M1530 (see bug #239649) with both a 2GB and a 256GB card in the internal reader. I have tried the cards in an external reader and they are fine. I even eventually tried the internal reader in Vista and it didn't have problems.
Sometimes the copy works fine, but usually these errors (end_request: I/O error) occur. It seems to be random, although it seems to work better after rebooting Ubuntu or after formatting the card. Once they occur, they keep occurring until I remount the card.
Worse still, the file system does not report that there are errors. It says they worked fine, but a diff shows otherwise (I opened bug 239647 for this).
