It is also a very dangerous tool as it can destroy all the partitions on your memory devices. Using a freeware tool called Fake Flash Test, we can make an attempt to detect these fake devices.įake Flash Test is a tool that can check if your newly bought USB pen-drives or memory cards are fake. As soon as we try to copy larger files or more files, they either give error or they just overwrite the older files.
Usually, we cannot find whether these storage devices are fake or original until after we have used them for a while. Similarly, a USB pendrive that is labeled 16 GB, could be only 2 GB in capacity. For example, some of these memory cards could be labeled 32 GB, but they could be only 4 GB memory cards. These fake devices pretend to be a large capacity flash memory storage devices, but actually have very small capacity.
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.When we buy flash memory devices from the internet, there are some odd times when we end up with a fake device. 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.
