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.
