Detailed Description

Header for a metadata block containing offsets and lengths to UTF-16LE descriptive strings.

Descriptive fields (all optional): creator, comments, media title/manufacturer/model/serial/barcode/part number, drive manufacturer/model/serial/firmware revision. Strings can be used to describe both physical medium and acquisition hardware. Length values include the UTF-16LE null terminator (two zero bytes).
