Fix: USB Drive showing wrong storage size issue in Windows 11 ,10

USB drives or any external storage media has become a part of our lives, a quick resolution to store photos, videos, or almost anything. But, what if you see that your USB drive is showing the incorrect highest storage size on the File Explorer? This mainly occurs when the storage device has become corrupted or contains some malicious files. If you are facing this issue, formatting the drive in the right format may help.


1. You can unplug the external drive and replug it back to the system.

2. Try to test the drive with another system. Check whether it is showing the correct size or not.

Now, here you will have several disks. You can identify the particular drive from the size of the drives. Like in our case, it is “Disk 2” with a disk size of 28 GB.

5. In the next step, you have to select the particular drive you are having this problem with. Modify and run this code to select the disk.

select disk <put the disk number here>


NOTE – Just replace the “put the disk number here” with the disk number that you have noted before.

Like –  In our case, the disk is “2”. So, the code will be like this –

select disk 2

Once it is done, close the Command Prompt. Open File Explorer and go to the “This PC” option.

You can do it in any format you want. Just you have to modify the command a little bit.
