When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one
trillion bytes. Your computer’s operating system may use a different standard of measurement and report a lower
capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be
available for data storage. Actual quantities will vary based on various factors, including file size, file format, features
and application software. Actual data rates may vary depending on operating environment and other factors. The
export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of
Commerce, Bureau of Industry and Security (for more information, visit www.bis.doc.gov), and controlled for import

Seagate Desktop HDD Product Manual, Rev. K 2

www.seagate.com Introduction

1.1 About the SATA interface

The Serial ATA (SATA) interface provides several advantages over the traditional (parallel) ATA interface. The
primary advantages include:

• Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers
or other configuration options.

• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.

• Scalability to higher performance levels.

In addition, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was
designed to allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of
the existing applications to work as normal.

The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is
no master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one
SATA host adapter, the host operating system views the two devices as if they were both “masters” on two
separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.

The SATA host adapter and drive share the function of emulating parallel ATA device behavior to provide
backward compatibility with existing host systems and software. The Command and Control Block registers, PIO
and DMA data transfers, resets, and interrupts are all emulated.

The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers,
referred to as the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional
information about how SATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA
Revision 3.0”. The specification can be downloaded from

www.sata-io.org.

Note

The host adapter may, optionally, emulate a master/slave environment to host software where two
devices on separate SATA ports are represented to host software as a Device 0 (master) and Device 1
(slave) accessed at the same set of host bus addresses. A host adapter that emulates a master/slave
environment manages two sets of shadow registers. This is not a typical SATA environment.

*All specifications above are based on native configurations.

** One GB equals one billion bytes and 1TB equals one trillion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating

following web page: http://www.seagate.com/support/warranty-and-replacements/
From this page, click on “Check to see if the drive is under Warranty”. Users will be
asked to provide the drive serial number, model number (or part number) and
country of purchase. The system will display the warranty information for the drive.
