I have had this happen on flash drives. Sometimes it shows 0 bytes available. Sometimes it shows like 2g available (on a 32g drive) Drive Manager does not fix it. Cannot delete partition and make new one.
found out that the command "Diskpart" works great.
Run diskpart
list disk
Note the disk number that corresponds to your USB drive (it should be obvious going by size)
select disk X where X is the number from step 4
list partition - There should be two, numbered 0 and 1, each about 7 GB
select partition 0
delete partition
select partition 1
delete partition
create partition primary
exit

ps. I use ImageUSB to create from an ISO - used it for both Win10 and Ubuntu. no problems.
