USB Disk Storage Format Tool
USB Disk Storage Format Tool is a free formatting utility by Authorsoft that formats USB flash drives, memory cards, and external storage devices to FAT, FAT32, NTFS, or exFAT. It handles drives that Windows' built-in formatter refuses to process, including those with corrupted file systems or write protection issues.
What it does
The interface is a single window. Select your USB device from the dropdown, pick a file system, and click Format. Quick Format erases the file table in seconds, while the full format option writes zeros to every sector, which is slower but more thorough for drives with bad sectors. Before formatting, you can run an error check that scans for file system corruption and bad sectors, then attempts to repair them.
The tool also creates DOS bootable USB drives. Check the "Create a DOS startup disk" box, point it to a folder with DOS system files, and the formatted drive becomes bootable. This is useful for BIOS updates and running DOS based diagnostics on machines that cannot boot from their main drive.
It works with USB devices from most major manufacturers including SanDisk, Kingston, Transcend, Corsair, HP, Toshiba, and PNY, as well as Compact Flash and SD/SDHC/SDXC cards.
Advantages
- Formats drives that Windows' built-in tool cannot handle
- Supports FAT, FAT32, NTFS, and exFAT
- Built-in error scanning and repair before formatting
- Can create DOS bootable USB drives for BIOS updates and recovery
Drawbacks
- Cannot create modern bootable USB (Windows installer, Linux) like Rufus can
- No support for internal hard drives or SSDs
- DOS boot creation requires you to supply system files separately
- Interface has not been updated in years and looks dated
Who it is for
I keep this tool around for one specific situation: when Windows tells me it cannot format a USB drive. It has saved several flash drives I was about to throw away. If you regularly deal with USB drives that stop working or show incorrect capacity, this utility is worth having on hand. For creating bootable Windows or Linux installers, Rufus is the better choice.
