There have been reports from other people about USB mass storage devices corrupting data. In general nobody has been able to find a cause. For testing, you might find it easier to write to the raw device rather than through a filesystem or to a partition. For instance, simply write a lot of 0s to /dev/sda, then read it back and see what you get. Or copy a file to /dev/sda and compare the result with the original file. If you can find a consistent pattern of corrupted bytes it might provide a clue.
