I tested these flash drives using the Flash Check utility (chkflsh.exe) and then verified that whether there are addresses The disk returns the same data when read. These drives showed errors near the "far end" of the memory, which is sometimes a sign of a QC error. This means the drive looks fine at first, but once you start using the full range of drives (which will be after 128GB writes) you are vulnerable. Unfortunately, more and more "cheap" flash drives are exhibiting this behavior and it takes time for customers to discover the problem. Don't use these flash drives unless you can't live with the damage; so. I don't think you should use these sticks.
