Ways to use Unallocated Space on USB Drive

USB flash drives are the portable memory devices that enable easy transfer of all your data between computers. They are convenient to use and hence most of them even use them for booting the computer. However, they do have some problems while sharing. One such potential problem is unallocated memory, in which a portion of your USB drive memory becomes inaccessible and useless either due to unreliable third party diagnostic tools or an incomplete reformatting of your USB drives.

Until and unless the unallocated disk space takes up larger section of your USB drive space it is not a problematic issue. Luckily, there are many ways in which you can effectively utilize this unallocated space on USB drive, among them two of the most effective methods are as listed below:

  • Now, just choose the “Manage” option from the drop-down menu offered, with this the “Computer Management” window will open up
  • In this window, you could see many categories among them go to “Storage” category and then select “Disk Management” option
  • Here a list of all the drives on your computer will be displayed, including your flash drive that is located on the right side of the Disk Management window
  • Select the drive representing your USB drive and right-click on it; a drop-down menu appears. Then choose the “Delete Partition” option.
  • By doing this entire USB drive will be created as one portion of unallocated space
  • Again right-click on the USB drive and from the drop down list select the “New Partition” option
  • Now, the “Partition Wizard” will open up wherein just select the partition type that you want to create like primary, extended or logical drive.
  • Then choose the partition size and assign a drive letter to the USB drive; else the disk Management program will assign it automatically. Now just click on “Finish” to complete the process.

With this all your unallocated space on the USB drive will be released and you can utilize it now. However, before doing this just take backup of your entire USB drive data.

Note: If you are asked for the administrator permissions then provide the required password and other details.

Step 2: Type the command list disk to find your USB drive’s number, it should be the same as disk’s number in Computer Management tool.

DISKPART> list disk

Disk #   Status         Size           Free     Dyn  Gpt

Disk 0    Online       298 GB      0 B

Disk 1    Online      7509 MB    6619 MB

Step 3: Now, choose the drive to work with based on the disk numbers listed, here the USB drive number is 1. Then type select disk <disk number> command.

DISKPART> select disk 1

Disk 1 is now the selected disk.
