: Heavy bad-block management may result in a lower usable capacity than the original. High Compatibility
Often mislabeled as a "USB 3.0" controller in budget devices (though it’s often native USB 2.0), the AU6998SN supports larger capacity NAND chips (up to 256GB). Its common failure includes (e.g., a 64GB drive showing 32GB) after a sudden eject or power loss. The repair tool can force a full capacity scan and restore the original space.
Standard formatting tools often fail for these chips. You need version-specific AlcorMP software.
