i have a SanDisk Cruzer Blade usb flash drive, and it had 32gb capacity. i installed windows 7 on it using winToUSB program. now i want to use it for other things instead, but it has only 14gb maximum capacity. I tried to mess around in disk managment, i tried to “delete volume” and create a new partition.
diskpart clean should remove all partitions from the drive and set it back to the original. if that is not working that usually is not a good sign.
there is an app called HP Disk Storage Format Tool. Google search for that and see if it will restore the full capacity. If that does not work and diskpart is not working you may be out of luck.
