1.1 About the Serial ATA interface
The Serial ATA 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 jump-
ers or other configuration options.
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
• Scalability to higher performance levels.
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial
ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disc drive in your current
system and expect all of your existing applications to work as normal.
The Serial ATA interface connects each disc drive in a point-to-point configuration with the Serial ATA host
adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two
drives are attached on one Serial ATA 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.
Note. The host adapter may, optionally, emulate a master/slave environment to host software where two
devices on separate Serial ATA 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 Serial ATA
environment.
The Serial ATA 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 Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device regis-
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-
tional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from www.serialata.org.

2.6 Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using
drive diagnostics. The specifications in the table below are defined as follows:
• Track-to-track seek time is an average of all possible single-track seeks in both directions.
• Average seek time is a true statistical random average of at least 5,000 measurements of seeks between
random tracks, less overhead.
*Measured in performance mode.
**Measured in quiet mode.
Note. These drives are designed to consistently meet the seek times represented in this manual. Physical
seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted
values. However, due to the manner in which these drives are formatted, benchmark tests that
include command overhead or measure logical seeks may produce results that vary from these
specifications.
2.7 Start/stop times
2.8 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 28.
2.8.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on
an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient
temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating
speed.
• Seek mode
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and
does not execute a read or write operation. Servo electronics are active. Seek mode power represents the
worst-case power consumption, using only random seeks with read or write latency time. This mode is not
typical and is provided for worst-case information.
• Read/write power and current
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-msec
delay, then a 16-sector read followed by a 32-msec delay.
200 - 320 GB models* 40 - 80 GB models**
Typical seek times (msec) Read Write Read Write
Track-to-track <0.8 <1.0 <0.8 <1.0
Average <8.5 <10.0 <11.0 <12.0

Standby to Ready (sec) 15 (max)
Ready to spindle stop (sec) 10 (max)
DiamondMax 21 Serial ATA Product Manual, Rev. A
17
• Operating power and current
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each
10 reads) and 20 percent drive idle mode.
• Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in
a random track location.
• Standby mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/
write electronics are in power-down mode.
Table 6: DC power requirements
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and
power to operational levels.

2.8.2 Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on
the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.
• Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
2.8.3 Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%
12V ± 10%
2.8.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems,
you can control power management through the system setup program. The drive features the following
power-management modes:
•Active mode
The drive is in Active mode during the read/write and seek operations.
Power modes Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
DiamondMax 21 Serial ATA Product Manual, Rev. A
19
• Idle mode
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc
access is necessary.
•Standby mode
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set
the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for
a specifiable length of time. The standby timer delay is established using a Standby or Idle command. In
Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive
accepts all commands and returns to Active mode any time disc access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive
buffer is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it
receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and
enters Standby mode with all current translation parameters intact.
• Idle and Standby timers
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and
begins counting down from its specified delay times to zero. If the standby timer reaches zero before any
drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the
drive accepts all commands and returns to Active mode when disc access is necessary.

surements are consistent with ISO document 7779. Sound power measurements are taken under essentially
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined
by the following equation:
(Number of seeks per second = 0.4 / (average latency + average access time)
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and
power to operational levels.

2.12 Reliability
2.12.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The product shall achieve an Annualized Failure Rate (AFR) of 0.34% (MTBF of 0.7 million hours) when oper-
ated in an environment of ambient air temperatures of 25°C. Operation at temperatures outside the specifica-
tions in Section 2.9 may increase the product AFR (decrease MTBF). AFR and MTBF are population statistics
that are not relevant to individual units.
AFR and MTBF specifications are based on the following assumptions for desktop personal computer environ-
ments:
• 2400 power-on-hours per year.
• 10,000 average motor start/stop cycles per year.
• Operations at nominal voltages.
• Temperatures outside the specifications in Section 2.9 may reduce the product reliability.
• Normal I/O duty cycle for desktop personal computers. Operation at excessive I/O duty cycle may degrade
product reliability.
The desktop personal computer environment of power-on-hours, temperature, and I/O duty cycle affect the
product AFR and MTBF. The AFR and MTBF will be degraded if used in a enterprise application.
2.13 Agency certification
2.13.1 Safety certification
The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections

• Move the device farther away from the radio or TV.
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.
If necessary, you should consult your dealer or an experienced radio/television technician for additional sug-
gestions. You may find helpful the following booklet prepared by the Federal Communications Commission:
How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Super-
intendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication num-
ber 004-000-00345-4.

2.14 Environmental protection
Maxtor designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemical substances.
2.14.1 European Union Restriction of Hazardous Substances (RoHS)
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical
substances, including Lead (Pb), in electronic products effective July 2006.
A number of parts and materials in Maxtor products are procured from external suppliers. We rely on the repre-
sentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our sup-
plier contracts require compliance with our chemical substance restrictions, and our suppliers document their
compliance with our requirements by providing material content declarations for all parts and materials for the
disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion of
any RoHS-regulated substance in such parts or materials.
Maxtor also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws
and regulations which restrict chemical content in electronic products. These systems include standard operat-
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora-
tory analytical validation testing, and an internal auditing process to ensure that all standard operating
procedures are complied with.
2.15 Corrosive environment
Maxtor electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light
industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845.
However, this accelerated testing cannot duplicate every potential application environment. Users should use
caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as
electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel
and gold films used in Maxtor products are especially sensitive to the presence of sulfide, chloride, and nitrate
contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be
exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an
ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber,
that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic
equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

3.0 Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1 Handling and static-discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis-
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:
Caution:
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal
chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire
installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until you mount it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids
the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are
used to seal out dirt and contamination.
28
DiamondMax 21 Serial ATA Product Manual, Rev. A
3.2 Configuring the drive
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no
master/slave relationship because each drive is considered a master in a point-to-point relationship. If two
drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they
were both “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices.
Serial ATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive
for proper operation; however, if you connect the drive and receive a “drive not detected” error, your SATA-
equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation. If
you have a motherboard or host adapter that does not support autonegotiation:
• Install a jumper as shown in Figure 3 below to limit the data transfer rate to 1.5 Gbits per second (and leave
the drive connected to the SATA-equipped motherboard or host adapter that doesn’t support autonegotiation)
or
• Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal
operation” (see Figure 3 below), and connect the drive to that adapter. This option has the benefit of not limiting
the drive to a 1.5 Gbits/sec transfer rate.
Figure 3. Serial ATA connectors
3.3 Serial ATA cables and connectors
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-
tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 9
for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive
and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind
mateable.
For installations which require cables, you can connect the drive as illustrated in Figure 4.
Figure 4. Attaching SATA cabling
Each cable is keyed to ensure correct orientation. DiamondMax 21 drives support latching SATA connectors.

3.4 Drive mounting
You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the
bottom-mounting holes. See Figure 5 for drive mounting dimensions. Follow these important mounting precau-
tions when mounting the drive:
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.
• Use only 6-32 UNC mounting screws.
• The screws should be inserted no more than 0.150 inch (3.81 mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

DiamondMax 21 Serial ATA Product Manual, Rev. A
4.2 Serial ATA device plug connector pin definitions
Table 9 summarizes the signals on the Serial ATA interface and power connectors..
Notes:
1. All pins are in a single row, with a 1.27 mm (0.050”) pitch.
2. The comments on the mating sequence apply to the case of backplane blindmate connector only. In this
case, the mating sequences are:
• the ground pins P4 and P12.
• the pre-charge power pins and the other ground pins.
• the signal pins and the rest of the power pins.
3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when
installed in a blind-mate backplane configuration.
4. All used voltage pins (Vx) must be terminated.

4.3.2 Set Features command
This command controls the implementation of various features that the drive supports. When the drive receives
this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an inter-
rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted.
Power-on default has the read look-ahead and write caching features enabled. The acceptable values for the
Features register are defined as follows:

4.3.3 S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni-
tors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines
that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable.
S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the Draft ATA-5 Standard.
This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that
supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the
drive uses.
Note. If an appropriate code is not written to the Features Register, the command is aborted and 0x 04
(abort) is written to the Error register.
