The last 4GB (3814 MiB) Is used for GrandMasUSB.
The remainder is formatted in NTFS, with a label of MyGrandMasUSB.
This is all Windows is aware of when plugged into a running Windows computer. GrandMasUSB is a custom installed version of Debian Linux, and ClamAV Anti Virus / AntiMalware. Both are OpenSource software and very well written and maintained. The user does not need to be any more proficient with a computer, than reading from screen; using arrow up and down and Enter.
