Today I got a promotional information USB stick from a retailer and I was
able to *fdisk* and *mkfs* it to a 3.9mb drive.  It seems like an odd
size.  Would it be safe to assume there is more space than it shows and can
it be unlocked and accessed?

This is what fdisk currently shows after formatting.

Unpartitioned space /dev/sdb: 3.9 MiB, 4111872 bytes, 8031 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Start   End Sectors  Size
   1  8031    8031  3.9M
