I installed Kali Linux on a flash drive, she even gets started. Then I wanted to make a place to save the files to then go into the Persistance of fashion.
When Kali scanning using fdisk-l , it is clear and even computer hard drives.
If you run Gparted, the USB drive shows 7.55 GB(although it has only 8GB, 3 of which must take Kali), and he sees the flash drive to format iso9690.
Several times I tried to overwrite the USB drive, nothing changed.
