This sounds a lot like issues I have had with a bad batch of USB sticks (don't know what manufacturer as they are branded advertising stock) whose wear levelling appears to go bad, resulting in all sorts of random re-mappings of data into other files. Do your corrupt files read the same if you copy them off multiple times? I found that ours didn't, which pointed fairly strongly at a hardware-level issue.
