The cache can hold multiple writes and collectively write them to the hard disk. 48-bit Logical Block Addressing (LBA) — HGST SATA drives support both 48-bit and 28-bit LBA and CHS-based addressing. LBA is included in advanced BIOS and operating system device drivers and ensures high capacity disk integration.
Serial ATA specification published by the SATA-IO organization as of the date of this document. Visit www.sata-io.org for details.

Each read segment consists of pre and post read sectors in addition to the host-requested sectors. This maximizes the amount of cache data in the drive’s buffer, thereby increasing the likelihood of cache hits and improving overall performance. HGST Hard Disk Drive Technical Reference Manual...

CAUTION: Screws that are too long can damage the hard drive. Hard drive screw penetration can differ between products depending upon hard drive design. HGST’s minimum design criteria is to always meet the SFF 8301 industry standard specification. The industry standard as defined in the SFF 8301 specifies a maximum of 3 mm screw penetration, and for a minimum of 2.4 mm of thread engagement from both the screw and the hard drive.
To avoid excessive wear on the drive due to the starting and stopping of the HDA, set the host’s disk inactivity timer to no shorter than ten minutes. HGST Hard Disk Drive Technical Reference Manual...

Recovery is similar to a typical TTR (Time To Ready) for the HDD HGST has added the Power Condition Log, which defines the support, enable bits, and timers for all power conditions. The power management timers start running after all Host commanded drive activity is complete, and will run during drive background operations, but do not take effect until those background operations are completed.
The SATA cable consists of four conductors in two differential pairs. The cable may also include drain wires to be terminated to the ground pins in the SATA cable receptacle connectors. See the SATA specification for cable specifications. The cable's maximum length is one meter. HGST Hard Disk Drive Technical Reference Manual...
Packaged Shock and Vibration The shipping packaging is designed to meet the National/International Safe Transit Association (N/ ISTA) standards for packaged products. The drive incurs no physical damage when subjected to the N/ ISTA standards. HGST Hard Disk Drive Technical Reference Manual...
See Figure 2 Actual drive case temperature should be below 60°C and within the 5-60°C operating ambient temperature. Unless still in HGST’s factory sealed bag which allows up to 40C without limit. Temperature Measurement Drive component temperatures measured at the drive baseplate thermocouple location must remain within the limits specified in Table 4.
No audible pure tones. RoHS (Restriction of Hazardous Substances) HGST hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU. RoHS aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.

DMA controller. Time-Limited Error Recovery (TLER) HGST has delivered coordinated error management in the form of Time Limited Error Recovery (TLER). TLER-capable hard drives will perform the normal error recovery and, after 7 seconds, issue an error message to the RAID controller and defer the error recovery task until a later time. With coordinated error handling, the hard drive is not dropped from the RAID array, thereby avoiding the entire RAID recovery, replacement, rebuild, and return experience.
Adaptation to environmental conditions is crucial to the successful deployment of RAFF. This design intelligently applies RAFF selectively and adapts to with individual drive parameters to maintain maximum performance in the hard drive. HGST Hard Disk Drive Technical Reference Manual...
PMR recording layer tends to be thicker than that used for longitudinal recording, providing increased signal for the read heads. All of these benefits enable HGST engineers to reliably pack more data on a given disk than is possible with conventional longitudinal recording.
Upon power loss, the drive utilizes stored spindle energy to back up the HDD cache to on- board flash. This allows deeper write queues which boosts performance, while minimizing data loss/ corruption such as write splices that can occur during unexpected power losses. HGST Hard Disk Drive Technical Reference Manual...
LED. A buffer circuit external to the device must be employed to drive the LED. The activity signal is based on an open-collector or open-drain active low driver. The device shall tolerate the activity signal being shorted to ground. HGST Hard Disk Drive Technical Reference Manual...
The drive also stores a set of attribute thresholds that correspond to the calculated attribute values. Each attribute threshold indicates the point at which its corresponding attribute value achieves a negative reliability status. HGST Hard Disk Drive Technical Reference Manual...
By incorporating DPP in our hard drives, HGST protects customer data with the ability to detect these type of rare events, and prevents incorrect data from being written to the media.
Operation of the drive at the minimum or maximum base casting temperature is intended for short time periods only. You can enhance the reliability of the HGST hard drive by ensuring that the drive receives adequate cooling. “Temperature Measurement” on page.17 Provides temperature measurements and other information that may be used to enhance the service life of the drive.

Defect Management Every HGST drive undergoes factory-level intelligent burn in, which thoroughly tests for and maps out defective sectors on the media before the drive leaves the manufacturing facility. Following the factory tests, a primary defect list is created. The list contains the cylinder, head, and sector numbers for all defects.
The Read/Write Retry procedure performs the actual retry operation. When an extended retry operation is successful, the controller continues with the command. The controller clears any changes in track offset or data DAC settings before the command continues. HGST Hard Disk Drive Technical Reference Manual...

Maintenance The hard drive requires no preventative maintenance and contains no user-serviceable parts. The service and repair of drives can only be performed at a HGST Service Center. Please contact your HGST representative for warranty information and service/return procedures. Observe the following precautions to prolong the life of the drive: Do not attempt to open the sealed compartment of the drive as this will void the warranty.
F.I.T. (Functional Integrity Testing) — A suite of tests HGST performs on all its drive products to ensure compatibility with different hosts, operating systems, application programs, and peripherals. This testing must be performed before the product can be released to manufacturing.
