From the Introduction
A mass-storage device can provide access to data for just about any purpose.
Every time you load an application or save a file on a PC, you’re
using a mass-storage device. A computer’s hard drive is a mass-storage
device, as are flash, CD, and DVD drives. Devices with dedicated functions—data
loggers, robots, and other embedded systems—can use mass storage
as well. Every mass-storage device contains a microcontroller, microprocessor,
or other intelligent hardware that knows how to access the contents of
the storage media. Read more...

Chapter 1: Mass Storage Basics
A mass-storage device is electronic hardware that stores
information and supports a protocol for sending and retrieving the information
over a hardware interface. The information can be anything that can be
stored electronically: executable programs, source code, documents, images,
spreadsheet numbers, database entries, data logger output, configuration
data, or other text or numeric data. Mass-storage devices typically store
information in files. A file system defines how the files are organized
in the storage media.
In Windows computers, mass-storage devices appear as drives in My Computer.
From Windows Explorer, users can copy, move, and delete files in the devices.
Program code can access files using file-system APIs or .NET’s File
class. (read more...(PDF))

Reviews
In technical writing, clarity is the name of the game. As someone who writes technical prose, I greatly admire Jan Axelson; she knows better than almost anybody else how to write clearly and how to explain complex technical issues so that her audience can understand them with minimal frustration. - EDN. Read the whole review.
From handling commands and data errors to interface specs, manipulating FAT file systems, and more, USB MASS STORAGE provides project managers and developers with all the basics on using industry standard commands, controllers, and ports. - Midwest Book Review/California Bookwatch.
