Comment 39 for bug 17881

I seem to have a very similar problem (Feisty).
I try copying files over to my Sony-Ericsson W300i and it...
a.) Slows copying at some point
b.) Stops copying at some point
c.) Copies (Never with a lot of files)
d.) Copies but makes disk unmountable ("Writing Data to Device"). It eventually comes up with an error.

Some of the above might be the same thing with my patience varying...

I don't think it helps that this device has 2 "drives" on it. One for phone internal memory, and 1 for memory card.

On a.) dmesg prints out
[ 1434.553640] sdb: rw=0, want=1945592, limit=1945231
[ 1434.553925] attempt to access beyond end of device
[ 1434.553930] sdb: rw=0, want=1945593, limit=1945231
[ 1434.554227] attempt to access beyond end of device
(quite a few more times)

I'm planning to eventually try this on gutsy where they have new USB Flash drive stuff.
