Repair USB Thumb Drive to Regain Space

Recover space from a Thumb Drive that shows less space than it should

  1. DCiAdmin
    My 16GB thumb drive recently wouldn't accept any files even though it had been formatted. Digging a bit deeper, I discovered that the drive had somehow become partitioned into many smaller sections. Fortunately, this is an easy fix.
    1. Place the thumb drive into a USB port on your computer
    2. In the Run or Search box, type diskmgmt.msc to open disk management
    3. Select your thumb drive's partition
    4. Right click on it and select the Delete Volume option
    5. This deletes the partitions and frees up the total space. NOTE: Any data on the drive is lost at this step.
    6. Right click in the newly emptied space and select Create Volume to recreate the full drive space
    7. Select the new Volume and Format.
    8. Your thumb drive will be at full capacity again.
