I recently installed Tails (Linux Distro) on my USB drive. I did it using an intermediary USB stick and i discovered when i installed the final Tails OS on the second USB drive that the size of the hard drive reduced from 15.1 GB to 2.43 GB.I rebooted my system to windows and tried formatting the hard drive, the size remained unchanged.Please what do i do. The flash drive originally had 15.1GB total disk space andd after the tails installation, it now has 2.43GB.
Hidden Unallocated Partition greyed out in Flash Drive after Linux Tails Installation

Lets remove unallocated space. First of all run Windows command line and type diskpart in the command prompt. Windows will ask you for Administrator permissions to run the tool. Then run list disk command to find your USB flash disks number. It should be the same as disks number in Computer Management tool. It was 1 in my case. Next you should chose the disk to work with. Type select disk <disk number> command, e.g. select disk 1. The next step is to clean all volumes and partitions on the disk. Use clean command to do that. The last step is to create a primary partition. You can do that using create partition primary command. Thats all. You should be able to format your flash disk now.
