The problem is that if I do this command: Open the Start Menu, search for Command Prompt, right-click on it when you see it in the results, and select Run as administrator. There’s a command that allows you to remove all the partitions, format your drive, and then re-create partitions on the drive. The wrong USB drive size issue can be fixed using Command Prompt as well. I read one guy saying it corrupt ALL the files.įix An Incorrect Size USB Drive Using Command Prompt I also want to know if it's true these fake pendrives ALWAYS corrupt the files (or some of them) you put there, even if you only use less than what they can hold. To adjust this pendrive to only use what it can hold. To know the actual true size of this flash drive. The problem is that I have no idea which programs can do each task. 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 for faults.I was given a fake 2 TB pendrive (with the 'Samsung' label in it) and while Windows 10 64-bit says it has 1.9 TB free and it's using exFAT, I did some research and noticed some programs can reveal the actual smaller size and perhaps this is fixed by you readjusting the partition size to fit what is real and not false information. 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 in preventing 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. It does have a password, which we dislike, but it 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.
