If your USB storage device (e.g. USB flash drive, removable hard drive, SD card) is experiencing problems like persistent data corruption, virus intrusion, invalid master boot record, presence of hidden partition (after making it a bootable USB), loss of capacity (formatted on non-PC), corrupt bootable sectors, bad sectors in firmware/controller, inability to format, then a low-level formatting tool like USB Low-Level Format can help you fix these faults reliably.
