11.10Sector Count Register

This register contains the number of sectors of data requested to be transferred on a read or write operation between the host and the device. If the value in the register is set to 0, a count of 256 sectors (in 28-bit addressing) or 65,536 sectors (in 48-bit addressing) is specified.

If the register is zero at command completion, the command was successful. If not successfully completed, the register contains the number of sectors which need to be transferred in order to complete the request.

The contents of the register are defined otherwise on some commands. These definitions are given in the command descriptions.

Table 28. Status Register

This register contains the device status. The contents of this register are updated whenever an error occurs and at the completion of each command.

If the host reads this register when an interrupt is pending, it is considered to be the interrupt acknowledge. Any pending interrupt is cleared whenever this register is read.

If BSY=1, no other bits in the register are valid.

Bit Definitions

 

BSY

Busy. BSY=1 whenever the device is accessing the registers. The host should not read or

 

write any registers when BSY=1. If the host reads any register when BSY=1, the contents of

DRDY (RDY)

the Status Register will be returned.

Device Ready. RDY=1 indicates that the device is capable of responding to a command.

DF

RDY will be set to 0 during power on until the device is ready to accept a command.

Device Fault. DF=1 indicates that the device has detected a write fault condition. DF is set to

DSC

0 after the Status Register is read by the host.

Device Seek Complete. DSC=1 indicates that a seek has completed and the device head is

 

settled over a track. DSC is set to 0 by the device just before a seek begins. When an error

 

occurs, this bit is not changed until the Status Register is read by the host, at which time the

 

bit again indicates the current seek complete status.

 

When the device enters into or is in Standby mode or Sleep mode, this bit is set by device in

DRQ

spite of not spinning up.

Data Request. DRQ=1 indicates that the device is ready to transfer a word or byte of data

 

between the host and the device. The host should not write the Command register when

CORR (COR)

DRQ=1.

Corrected Data. Always 0.

IDX

Index. Always 0

ERR

ERR=1 indicates that an error occurred during execution of the previous command. The

 

Error Register should be read to determine the error type. The device sets ERR=0 when the

 

next command is received from the host.

HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, HTS541612J9SA00, HTS541660J9SA00 specifications

The Hitachi HTS541660J9SA00, HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, and HTS541612J9SA00 are a series of hard disk drives that showcase Hitachi's commitment to high-performance storage solutions. These drives belong to the Travelstar series, which is designed primarily for mobile computing applications, such as laptops and external storage devices. Their compact design and reliable performance make them suitable for users seeking efficient storage in portable settings.

One of the primary features of these drives is their SATA interface, which allows for fast data transfer rates, thereby enhancing overall system performance. The SATA II interface provides a maximum transfer rate of up to 3.0 Gbps, ensuring that these drives can keep up with the demands of modern computing.

The storage capacity of these models varies, with options such as 160GB, 250GB, and 320GB, catering to diverse user needs for both personal and professional use. The HTS541660J9SA00 provides a generous 160GB capacity, while the HTS541680J9SA00 offers up to 320GB, making them suitable for users who require significant storage space for media files, applications, and documents.

In terms of performance, these hard drives boast a rotational speed of 5400 RPM, striking an optimal balance between speed and energy efficiency. This speed ensures relatively quick access times while consuming less power compared to faster 7200 RPM drives, making them ideal for battery-powered devices.

Another significant characteristic of these drives is the use of Hitachi’s Advanced Format technology. This technology increases the physical sector size of the drives to 4KB, enhancing error correction and overall data integrity. This larger sector size allows for greater data efficiency, significantly reducing the overhead associated with data storage.

Furthermore, these drives are designed with Shock Protection technology, which helps to safeguard the drive's internal components from physical shocks caused by accidental drops or bumps. This feature is especially important for mobile storage solutions, where portability can lead to unintentional impacts.

In conclusion, the Hitachi HTS541660J9SA00, HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, and HTS541612J9SA00 hard disk drives are exemplary choices for anyone seeking reliable, efficient, and portable storage solutions. With their combination of adequate capacity, enhanced data management technologies, and robust design, these drives effectively meet the demands of today’s mobile computing needs.
