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.

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.

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 or exceed  
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.

Power specifications  
The drive receives DC power (+5V and +12V) through a native SATA power connector. See Figure 5 on  
page 25.  
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.  
• Operating power and current  
Operating power is measured using a standard Surveillance Storage Profile.  
• 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.

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.

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.  
• 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.

This equipment is designed to provide reasonable protection against such interference in a residential installa-  
tion. However, there is no guarantee that interference will not occur in a particular installation. If this equipment  
does cause interference to radio or television, which can be determined by turning the equipment on and off,  
you are encouraged to try one or more of the following corrective measures:  
• Reorient the receiving antenna.  
• Move the device to one side or the other of the radio or TV.  
• 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.

Environmental protection  
Seagate 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 Seagate products are procured from external suppliers. We rely on the  
rep-resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our  
supplier 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.  
Seagate 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  
Seagate 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 corro-  
sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-  
ver, copper, nickel and gold films used in Seagate 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 vulca-  
nized 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.

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:  
• Keep the drive in the electrostatic discharge (ESG) bag until you are ready for installation.  
• 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.

3.2  
Breather filter hole precautions  
This section contains information regarding the precautions to take with the breather filter hole in Seagate hard  
disc drives. Take the proper precautions to ensure full functionality and to prevent possible damage to the  
drive.  
Breather hole  
Do not cover or seal  
this hole.  
Figure 3  
Breather filter hole location  
Caution: Do not cover, seal, or insert any object into this hole.  
This hole has two purposes:  
• To allow condensation inside the hard disc to escape  
• To allow air pressure inside the hard disc to equalize with ambient pressure  
Note. If this hole is covered, sealed, or penetrated by any object, drive reliability may be compromised  
and could lead to permanent damage--doing so voids the warranty.

3.3  
Configuring the drive  
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host  
adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point  
relationships. 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 means 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:  
• Configure the jumper block with a jumper as shown in Figure 4 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, set the drive jumper block set to “3 Gbits per second  
operation” (see Figure 4 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.

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 6  
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 5.

3.5  
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 6 on page 26 for drive mounting dimensions. Follow these important  
mounting precautions 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).

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:

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.  
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 ) that elimi-  
H
nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
http://seatools.seagate.com.  
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.

4.3.4  
Streaming feature set support  
The Streaming feature set is an optional feature set that allows a host to request delivery of data from a contig-  
uous logical block address range within an allotted time. This places a higher priority on time to access the  
data than the integrity of the data. Streaming feature set commands only support 48-bit, LBA-mode-only  
addressing.  
Seagate implements the following Streaming commands:  
• CONFIGURE STREAM  
• READ STREAM DMA EXT  
• WRITE STREAM DMA EXT  
Command Completion Time Out (CCTO) errors are not deferrable on DMA operations, as they require some  
DMA engine clean up on the host side. Therefore, Seagate does not anticipate supporting any configurations  
where a CCTO needs to hide from reporting as an error, and simply show up in a Stream Error log. Since the  
Stream Error logs were intended to be used to report deferred errors such as this, Seagate has not imple-  
mented them.  
4.3.4.1  
Identify Device command  
These drives will set word 84 bit 4 (Streaming Feature Set Supported) and word 87 bit 4 (Configure Stream  
command was issued) when a non-zero default time limit has been set for either reading or writing. If the host  
reconfigures both defaults to 0, the bit will clear.  
Word 95 (Stream Minimum Request Size)  
World 95 contains the number of sectors that provide optimum performance in a streaming environment. This  
number shall be a power of two, with a minimum of eight sectors (4096 bytes). The starting LBA value for each  
streaming command should be evenly divisible by this request size.  
Words 96, 97, and 104  
Unsupported.  
Words 99:98  
These words define the fixed unit of time that is used only in the Command Completion Time Limit (CCTL) that  
is passed in streaming commands. The unit of time for this parameter is microseconds. For example, a value of  
50000 indicates 50 ms.  
4.3.4.2  
Streaming commands  
Streaming commands are defined to be time-critical data transfers rather than the standard data-integrity-criti-  
cal commands. Each command shall be completed within the time specified in the CONFIGURE STREAM  
command or in the streaming command itself to ensure the stream requirements of the AV-type application.  
The drive may execute background tasks as long as the READ STREAM and WRITE STREAM command exe-  
cution time limits are still met.  
The host may use the CONFIGURE STREAM command to define the default Command Completion Time  
Limit (CCTL) for reads and writes independently--this assists the device in setting up its caching for best per-  
formance. If the host does not use a CONFIGURE STREAM command, the device shall use the CCTL speci-  
fied in each streaming command, and the time limit is effective for one time only. If the CCTL is not set by a  
CONFIGURE STREAM command, the operation of a streaming command with a zero CCTL is device vendor  
specific. "Stream ID" as noted in the ATA specification is not used by the Seagate implementation.

The streaming commands may access any user LBA on a device. These commands may be interspersed with  
non-streaming commands, but there may be an impact on performance due to the unknown time required to  
complete the non-streaming commands.  
The streaming commands should be issued using a specified minimum number of sectors transferred per com-  
mand, as specified in word 95 of the IDENTIFY DEVICE response. The transfer length of a request should be  
a multiple of the minimum number of sectors per transfer, as should the starting LBA of any streaming com-  
mand.  
Urgent bit  
The Urgent bit in the READ STREAM and WRITE STREAM commands is ignored. Therefore, bits 9 and 10 of  
IDENTIFY DEVICE data words 84 and 87 shall remain clear.  
Flush to Disk bit  
The Flush to Disk bit in the WRITE STREAM command specifies that all data for the specified stream shall be  
flushed to the media before posting command completion. If a host requests flushes at times other than the  
end of each Allocation Unit, streaming performance may be degraded. Using the SET FEATURES command  
to enable/disable caching may not affect caching for streaming commands.  
Not Sequential bit  
The Not Sequential bit specifies that the next LBA(s) after those requested in the current READ STREAM com-  
mand are not anticipated to be used in a subsequent READ STREAM command. This information may help  
the device with pre-fetching decisions.  
Read Continuous bit  
If the Read Continuous bit is set to 1 for the command, the device shall attempt to transfer the requested  
amount of data to the host within the Command Completion Time Limit even if an error occurs. The data sent to  
the host by the device in an error condition is vendor specific.  
Write Continuous bit  
If the Write Continuous bit is set to 1 for the command and an error is encountered, the device shall still attempt  
to complete the transfer within the requested time. If an error occurs and cannot be resolved within the Com-  
mand Completion Time Limit, the erroneous section on the media may be unchanged or may contain unde-  
fined data. A future read of this area may not report an error, even though the data is erroneous. If the Flush Bit  
is set to 1 on the STREAM WRITE command and the data cannot successfully be written to the media, then  
the drive will report a Stream Error on the command.  
Handle Streaming Error bit  
The Handle Streaming Error bit specifies to the drive that this command starts at the LBA of a recently reported  
error section, so the device may attempt to continue its corresponding error recovery sequence where it left off  
earlier. This mechanism allows the host to schedule error recovery and defect management for content critical  
data.

Read Stream DMA (2Ah)  
Protocol: DMA In  
This command reads from 1 to 65536 sectors as specified in the Sector Count register. A value of 0000h in the  
Sector Count register requests 65536 sectors.  
The RC bit indicates that the drive operate in a continuous read mode for the READ STREAM command.  
When RC is set to 0, the drive shall operate in normal streaming read mode.  
When the Read Continuous mode is enabled, the drive shall attempt to transfer data of the requested length  
without setting the ERR bit to 1. The SE bit shall be set to 1 if the data transferred includes errors, unless the  
transfer is unable to finish within the CCTL, in which case a CCTO error will be reported (see below). If an error  
is encountered, it may be necessary for the drive to pad the data being transferred to fulfill the host's requested  
transfer size. The implementation of the padding is vendor specific.  
If the drive is unable to transfer the correct amount of data by the CCTL, the drive will set the ERR bit to 1 and  
the BSY bit to 0 in the Status Register, and the CCTO bit to 1 in the Error Register.

Write Stream DMA (3Ah)  
Protocol: DMA Out  
The Write Stream DMA command allows the host to write data using the DMA data transfer protocol. This com-  
mand allows for the host to specify to the device that additional actions need to be performed prior to the com-  
pletion of the command if the required bits are set.  
If the Write Continuous bit is set to 1, the device shall attempt to not stop execution of the command due to  
errors. If the WC bit is set to 1 and errors occur in the transfer or writing of the data, the device shall attempt to  
continue to transfer the amount of data requested and then provide ending status with the BSY bit cleared to  
zero, the SE bit set to 1, the ERR bit cleared to 0. If the WC bit is set to 1 and the Command Completion Time  
Limit expires, the device shall stop execution of the command and provide ending status with the BSY bit  
cleared to 0, the SE bit clear, the ERR bit set, and report the fact that the Command Completion Time Limit  
expired by setting the CCTO bit in the error register. In all cases, the drive shall attempt to transfer the amount  
of data requested within the Command Completion Time Limit even if some data transferred is in error.  
Additionally, if the F bit is set for a Write Stream command, the drive shall conclude processing for the com-  
mand (including flushing it to the media) before posting status.

4.3.4.3.1  
Time-constrained operations  
In general, time constraints have impacts not only on data transfer between the drive and the host, but also on  
the drive’s internal motion and movement of data to and from the internal buffer (cache). If the drive moves its  
actuator to access some data other than what the host is (or shortly will be) accessing, there will be an  
unavoidable delay before the actuator can be moved to where the host needs it to be to service a command.  
SV35 Series SATA Product Manual, Rev. B

If write caching is allowed, the actuator could be busy servicing a cached write at virtually any time. The impli-  
cation is that a timeout on a read command could actually be due to a cached write. To address this case:  
• Streaming commands will not time out if there is a non-streaming cached write in progress  
• all cached write data is discarded if a timeout occurs on a streaming command  
• when the host issues a streaming read to the drive, internal drive activity is limited to minimize the chances  
that significant time will be spent on a normal write, and  
• timeouts are inhibited if this case is occurring.  
4.3.4.3.2  
Non-cached streaming writes use model  
The host can issue streaming writes. If this is done, it is recommended that the host either set the F bit or dis-  
able write caching. If the host does neither, the drive has no way to accurately report the failure location and  
length in the event of a write failure on a cached write. Disabling caching or using the F bit will cause some per-  
formance loss compared to the case where caching was allowed. The most straightforward way to ensure that  
performance is maintained in this usage model is for the host to issue large writes, so that the seek time is  
insignificant when compared to the amount of time that the host can allow the command to consume. If the  
host’s time limit allows, the drive will perform internal defect management on any defective sectors encoun-  
tered. If the drive runs out of time during a write of this type, any currently cached sectors in the drive’s buffer  
will be discarded. If the error occured in the LBA range of the current command (rather than a cached com-  
mand), the portion of that write that may not have been successfully written to the media will be reported to the  
host in the ending status of the write command.

Non-streaming writes  
In non-streaming writes, the drive does not discard any write data, but rather protects the data as if it were in a  
non-timed environment altogether. The cache algorithm ensures that if a write to the media is begun, it will be  
finished during the write command on the ATA bus, and will not adversely affect a streaming read.  
A system may use this mode during boot, and then switch over to Streaming Writes for operational mode, back  
again to untimed mode for maintenance, etc. This behavior can be safe as long as a Flush Cache command is  
issued and completed before switching between write command types.
