This may relate to that MRU/FIFO/circular buffer thread elsewhere on here, but I want to pose it as fresh question.
If we use TeraCopy's file verification function, where it computes the checksum of the original file, and then checks is against the copied file, to see if they match, that will catch actual file errors in copying. But when it goes on to the next file, that doesn't mean that the previously copied file is still present. So a devious fake drive could have any number of files copied to it, that would verify at the moment, but wouldn't be there if a second round of comparisons was done for all the files, after the fact.
Or is this just speculation that doesn't happen in real life, with actual fake products?
