This exact error (and some others) happened to me frequently a few 
months ago with a bad RAID card driver.  At random (and somewhat 
infrequently) corrupt data would be written to a file.  I was able to 
reproduce the problem by making several copies of a gigabyte file and 
then comparing the md5sums.  The solution was to upgrade my kernel.
