Overall Rating: 4.0/5 Best for: PNY drive owners, IT pros, and anyone needing a quick fix for corrupted or unreadable USB flash drives. Introduction Most of us have been there: you plug in a USB flash drive, and Windows either claims it “needs to be formatted,” shows the wrong capacity (e.g., 8GB instead of 128GB), or refuses to recognize it entirely. PNY’s free, standalone format utility is designed to cut through these headaches—specifically for PNY drives, though it often works on other brands too.
