FakeFlashTest Tutorials & Guides
FakeFlashTest is a small Windows freeware tool by Steve Si (RMPrepUSB) that checks whether a USB flash drive or microSD card really holds the capacity printed on it. It writes test blocks across the drive and reads them back: if data written past the real capacity comes back wrong, the drive is fake. Start with the download page — the tool comes as a password-protected ZIP (password “fake”) and must be run as Administrator.

Not Sure Where to Start?
New drive, nothing on it yet? Run the Quick Size Test guide — it is the fastest screen. Note that Quick Size Test is destructive: it erases the drive, so use it on an empty drive.
Drive already has files on it? Read the Test Empty Space guide first. That mode is designed to preserve existing files, but back up anything important before any test.

Remember: a quick pass is a screen, not a full fault test. FakeFlashTest cannot repair a fake drive, and data already overwritten on a fake drive is usually unrecoverable.
