Rixter, your lost GB can be explained in this thread http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Problems-with-16-GB-sandisk-cruzer/td-p/272805
Until the industry promotes products read as gibibytes or GiB (binary) then this will always be confused.
To have a FULL 16GiB available the drive would have to have a REAL storage capacity of 17.18GB (rounded) or 17179869184 Bytes.
The 16 GB Sandisk Cruzer starts out with only 15698231296 bytes or 15.7GB which is actually only 14.62GiB.
