    Windows 10 explorer shows incorrect USB drive size (DISKPART is OK)

    I have a brand new Samsung 128 GB FIT flash drive that came formatted as exFAT. I reformatted it as FAT32 following the instructions on this page using the guiformat app referenced in the article:

    https://www.howtogeek.com/316977/how...32-on-windows/

    Now windows 10 explorer shows the drive as having a total capacity of only 53.6 GB. DISKPART shows the drive as having a single partition of 119 GB with no unallocated space. Partition Master similarly shows a single partition of 119.51 GB with no unallocated space. Windows Disk Management shows a single partition of 119.51 GB with no unallocated space in the lower pane, but only a 53.67 GB Capacity in Disk Management's drive listing in the top pane (see screenshot below). What is going on here? Why don't all of the applications agree on the USB drive size? Why are two different parts of the same application reporting two different size numbers for the same drive?

    USB or External Drive shows wrong size or incorrect capacity

    File Explorer Shows Incorrect File Size when copying from USB to C Drive folder

    Hello Peter,

    the issue might be caused if there is virus in the external drive (USB). I suggest you to perform a virus scan using Windows Defender or any other antivirus software installed (if any) in your computer and check for status.

    If the issue still persists, then suggest you to update the USB drivers by following the steps provided below:

    • Press Windows + X keys and select Device Manager.
    • Expand Universal serial bus controllers.
    • Right click on the drivers and select Update driver software.

    Hope this helps. Keep us posted on the status for further assistance.

    Thank you.
