USB Disk Storage Format Tool utility allows you to quickly and thoroughly format virtually any USB flash drive with your choice of FAT, FAT32, exFAT, or NTFS partition types. Neowin Login. May 2, 2018 - For Mac users, it can be very quick to format PNY USB flash drive on Mac with Disk Utility, but any Mac data recovery software can easily.
If you have purchased a ' fake' flash drive (one that has been 'clocked' so it reports a larger capacity than it actually is), then although a factory utility described below may appear to fix it and correct it so that it reports it's true capacity, it will probably fail at some time in the future, as these devices often contain defective memory chips which failed the manufacturers tests and were sold off as defective 'reduced capacity' Grade C stock (or just pinched from the dustbins behind the factory!). Before using the tools mentioned in this Tutorial to reprogram your USB drive, check that it is not a 'fake' USB drive by running. WARNING: your USB drive may still be 'bad'. Many of these factory mass-production tools do not test the memory very well at all. The Alcor tool in particular does not.
You can usually get a clue as to how thoroughly they test the memory by how long it takes the utility to program the controller and format the memory. If it only takes a few minutes for an 8GB USB stick, then it is not thoroughly testing the memory! For this reason you are strongly advised to TEST THE USB STICK after using an MP tool, by using RMPrepUSB Quick Size Test first - and if this passes, run H2TESTW on the formatted, empty USB stick.
