Kort sagt

Drive Verdict: USB Checker tests USB flash drives for fake capacity, real read and write speeds, and the actual USB link speed. It writes test data to the whole drive, checks every block, and produces a Passed, Needs attention, or Failed report that can be saved as PDF or copied as text. What stands out is that it can show a drive's true usable size when the drive is counterfeit.

Om appen

Cheap flash drives often lie about their size: they accept your files and quietly lose them. This app tells you the truth about any drive you plug in.

FULL CHECK • Fills the free space with test data and reads every block back • Each block is stamped with its own position, so a counterfeit can't fake a pass • Tells you the drive's real usable size if it's fake • Your existing files are left alone, and test files are always deleted

SPEED TEST • Real write and read speeds, measured without the Mac's cache • Small random reads, for how snappy the drive feels

CONNECTION CHECK • Shows the actual USB link speed and explains problems plainly, like "this USB 3 drive is running at USB 2 speed, try another cable"

REPORTS • A clear Passed / Needs attention / Failed verdict • Save as PDF or copy as text, handy for a refund request • History of every drive you've checked

SAFE Only drives you plug in can be tested, never your Mac's startup disk. It writes only to the drive you choose.
