Missing memory on USB flash drive isn't visible with disk management

Question

Just as the title says, I have a USB flash drive (16 Gb) that seems to have lost ~2 Gb. Both Windows Disk Managment and DiskPart agree that there's only 14 Gb be had, but I know it had more when I bought it.

I had put an OS image on it as recovery media previously, but I had thought a simple reformat and once-over with Disk Management or DiskPart would be enough.

Basically, What's going on here?

Answer 1

Type these commands in Command Prompt with adminstrator

diskpart select disk 1 clean create partition primary format fs=fat32 quick
