You're going to need to do testing to isolate where the corruption is
occurring.  For example, do the md5sums of these files change on the
file system?  From what you say, I would suggest that the Samba server
is not the cause of the problem.  If you could rule it out, then that
leaves the raid drivers as the probable suspect.  I have heard of data
corruption with hardware raids like 3ware under linux before.
