Detect Fake Storage Devices
Did you encounter a fake USB flash drive or SD Card that promised you higher storage capacities but offered only a fraction of it? The tools covered in this post can let you check, test and spot a fake USB device by running storage tests on these devices.
RMPrepUSB
RMPrepUSB is a great all in one USB tool that lets you perform a lot of operations on a USB drive. It also lets you create portable Windows installer and install Linux on the USB drive itself. RMPrepUSB offers a feature called ‘Quick Size Test’. Running this test would write some blocks to the device and then try to read it. By doing so, the program can calculate the actual capacity of the device and detect any counterfeit device. Make sure that you have a backup of your data before running this test as it is destructive in nature and will delete everything from your USB drive. Also, the test is not a thorough one, which gives it an advantage of being faster. We’ve also covered a thorough test in this post. Quick Size Test can take up to a few minutes to complete. There is another tool from the same developer called FakeFlashTest which is more of an extended version of Quick Size Test. You can download FakeFlashTest if you are looking for more options.

H2TESTW
H2testw is rather an old tool that runs a thorough test on a USB device that verifies the actual capacity of the device. You can specify your USB drive and then select the mode in which you want to test the drive. Either you can test the entire available space, or you can specify the number of MBs that you prefer to scan. Now hit the ‘Write+Verify’ button to start writing the data to the drive and then read it back to verify the capacity. If the drive already has test data, you can directly skip to verifying the drive. Since it runs a thorough test, H2testw is slow and can take hours. Click here to download H2testw.
CheckFlash
CheckFlash is another tool aimed to provide features such as checking and verifying USB drives. Other than that it can show you the drive map and other info such as read and write speed and total time elapsed in the test. Click here to download Check Flash.
ChipGenius
ChipGenius is a little different from other tools on this list. It lets you view some essential information about all the USB devices connected to your computer. You can view the manufacturer information, serial number and other details to verify if the device is fake or not. The tool also has an option to check Fake capacity, but for that, you need to download additional software and place it in the same folder as ChipGenius. Click here to download ChipGenius. So, these were a few tools that would let you verify a USB drive and spot a fake one. Most of the tools will also work with SD cards loaded in a card reader. Now you can easily spot a fake device and raise a concern with the retailer or online platform from where you bought the device.
