64GB USB flash drive shows 32GB problem
I have a 64GB flash drive, but it shows only 32GB in Window Disk management, the rest 26GB shows unallocated space, I tried format, delete operations, but in vain, how can I get them back? I need to back up a drive, so I need about 50GB free space, how can I make my 64GB USB work again?
Windows Disk management cannot erase drives, no local drives or external/USB hard drive or flash drives, so we need to use third party tool to make the disk clean again. In ByebyeData Eraser, the option Erase disk is able to erase everything on the USB drive, including partition table and all the traces of the files and folders you once stored. Once the USB drive is clean, you can format it again in Disk management and all the 64GB will show as one drive.
