Combine All Partitions of a USB Flash Drive

A USB flash drive may show multiple small partitions after being used as boot media or recovery media. To make it normal storage again, back up files, remove the old partitions, and create one full-size partition.

Before You Start

• Copy useful files off the USB drive first.
• Confirm the disk number and capacity before deleting partitions.
• Do not select an internal Windows disk.
• Use exFAT for broad compatibility or NTFS for Windows-only use.

Windows Method: Delete and Recreate the USB Volume

1. Open Disk Management and find the USB drive by capacity.
2. Delete each old USB partition if Windows allows it.
3. Right-click the unallocated USB space and choose New Simple Volume.
4. Use the full capacity, assign a drive letter, and format as exFAT or NTFS.
