AMWTA fake card is set up to report a large size, often 128 GB to 2 TB, while holding much less. It works normally until it fills past its real size; then new files overwrite old ones or come back as rubbish.
- Open Fake Card Tester and choose the cardNo administrator password is needed. The test uses only free space, so empty the card first for a full check.
- Let it writeIt fills the free space with test files in a folder called AMWT card test.
- Take the card out and put it backThis makes the check read from the card, not from the computer's memory. You can skip it, but the result is less certain.
- Read the resultGenuine, fake or failing, with how much really works and the write and read speeds. The test files are deleted.
A fake card should not be used for anything you care about. Ask the seller for a refund; the result screen gives the claimed and real sizes.
Failing means some data came back wrong but the card isn't simply wrapping round. Treat it as unreliable.
