I have a similar problem with an usb pen drive, which is mounted with
vfat (my car radio only likes vfat).
For instance, 350MB of a 400MB file are copied very fast, then I get
some timeout and device descriptor read messages. The writing never
finishes and the fs is corrupted.
First I thought the drive was damaged, but under Windows it works fine,
so it must be an issue related to how copying under linux works.
