So the goal of my post i to show to you how to check if your usb flash drive is counterfeit.
I suggest to buy usb flash drive in the certified reseller and be careful with eBay, Amazon and the others. Some SW like MPToolcan easily do this counterfeiting technique so it's clear that it's very simple and every not honest reseller can do this very simply. It's very simple: a mod in the memory controller make more space visible to the operating system. The war of lowering the prices is always increasing and very often we've to be careful with the extreme deals: the china market have introduced a cool counterfeiting technique called ShengJi (upgrading size). The second is Test Empty Space this one writes test files to the remaining free space on your drive - this test is not destructive, but if you do have a fake, then you could lose your data.įakeFlashTest is designed to perform a quick check to verify if a flash memory device is fake (i.e., they have been programmed to lie about their size) it does not check all memory faults.From 4€ ( Verbatim Store 'n' Go Pin Stripe 4GB, LEXAR USB JUMPDRIVE S50 4GB) to ~800-1000€ ( Kingston DataTraveler 310 256GB, Kingston DataTraveler HyperX Predator 256GB, DataTraveler HyperX Predator 1TB) The first is the Quick Size Test it will check your drive and report the actual capacity and warn if the drive is fake - this test is destructive and the author states that you WILL lose files. But that is not all it can help prevent corruption for example, a 32 GB SD card may only have 4 GB of memory, and once you fill that 4 GB space, it can potentially become corrupted, resulting in a loss of all the data stored.įakeFlashTest includes two tests, and due to the nature of these tests, we strongly recommend backing up all data stored in the test subjects. This is a pretty slick and simple tool for verifying that you have the memory size you paid for.
FakeFlashTest is for testing the actual memory size of USB Flash Drives and SD cards.
