Hello! Yes, there are software programs that you can use to check the real capacity of your flash drive. One popular program is H2testw, which is a free utility that checks your flash drive for errors and also determines its actual capacity. Here are the steps you can follow to use H2testw:
1. Download H2testw from a reliable source online.
2. *********** flash drive into your computer and open H2testw.
3. Select your flash drive from the drop-down menu and click "Write + Verify" to start the test.
4. Wait for H2testw to complete the test, which can take several hours depending on the size of your flash drive.
5. After the test is complete, H2testw will display the actual capacity of your flash drive. If the capacity is significantly less than what your flash drive is supposed to have (e.g. 512GB), then it is likely that your flash drive is fake.
Keep in mind that if your flash drive is fake, formatting it will not change its actual capacity. It's best to contact the seller or manufacturer to resolve the issue. Hope this helps!
