    How to utilize unallocated space on a thumb drive


    Hi,

    I dont know why this happened, but my USB drive (64 GB Transcend) ended up with half its storage capacity being unallocated. I have tried Windows Disk Manager to have it allocated again in order to partition it, but to no avail. When I right-click, all the options are greyed out. Is there anything I can I do to reclaim the lost space or do I simply have to come to terms with the fact that the thumb drive is beyond repair. I mean, there is still 32 GB left, but it is annoying to know I could have had double that.

    My system is running Windows 10. By the way, is Easeus Partition Master a good choice for the job. I came across this software while browsing for a solution.

    If the Disk Management "Extend Partition" option is greyed out you'll need to repartition/reformat it. Copy your files to another drive, delete the current partition, then create a new one that uses the whole drive. If Disk management won't do it, you'll have to use diskpart. Option two here, just skip the "active" command. http://www.eightforums.com/tutorials...e-windows.html If you want NTFS instead of fat32, format fs=NTFS quick

    Hi there

    1) Insert the USB stick into USB slot and type the following commands from admin cmd prompt

    2) DISKPART
    3) LIST DISK
    4) SELECT DISK 4 (assume it's Disk nr 4)
    5) CLEAN <=============================== Do not Miss this command
    6) CREATE PARITION PRIMARY
    7) ACTIVE (Optional but use this if you want to create a BOOTABLE USB)
    8) FORMAT FS=NTFS QUICK

    Cheers

    For flash drive. You can either format with NTFS or ExFat. However, NTFS on flash memory has been known to be inefficient for quite some time. exFAT’s smaller footprint/overhead

    ExFAT is real nice for USB thumbdrives but it seems to be lesser accepted/widespreaded than NTFS. You could have issues running an ExFAT USB drive under WinXP for instance.

    For XP. You need: Download Update for Windows XP (KB955704) to support ExFat
