[Diagnostic code]

X'01': No Error Detected.

X'02': HDC Register Compare Error

X'03': Data Buffer Compare Error.

X'05': ROM Sum Check Error.

X'80': Device 1 (slave device) Failed.

Error register of the master device is valid under two devices (master and slave) configuration. If the slave device fails, the master device posts X’80’ OR (the diagnostic code) with its own status (X'01' to X'05').

However, when the host system selects the slave device, the diagnostic code of the slave device is posted.

(3)Features register (X'1F1')

The Features register provides specific feature to a command. For instance, it is used with SET FEATURES command to enable or disable caching.

(4)Sector Count register (X'1F2')

The Sector Count register indicates the number of sectors of data to be transferred in a read or write operation between the host system and the device. When the value in this register is X'00', the sector count is 256.

When this register indicates X'00' at the completion of the command execution, this indicates that the command is completed successfully. If the command is not completed successfully, this register indicates the number of sectors to be transferred to complete the request from the host system. That is, this register indicates the number of remaining sectors that the data has not been transferred due to the error.

The contents of this register has other definition for the following commands; INITIALIZE DEVICE PARAMETERS, FORMAT TRACK, SET FEATURES, IDLE, STANDBY and SET MULTIPLE MODE.

(5)Sector Number register (X'1F3')

The contents of this register indicates the starting sector number for the subsequent command. The sector number should be between X'01' and [the number of sectors per track defined by INITIALIZE DEVICE PARAMETERS command.

Under the LBA mode, this register indicates LBA bits 7 to 0.

MPE3XXXAT specifications

The Fujitsu MPE3XXXAT series is a robust line of hard disk drives (HDDs) known for their reliability, performance, and advanced technology. Designed primarily for enterprise storage solutions, these drives cater to high-demand environments such as data centers, servers, and workstations. With capacities ranging from hundreds of gigabytes to several terabytes, the MPE3XXXAT series offers scalable storage options to accommodate a variety of applications.

One of the standout features of the MPE3XXXAT series is its high rotational speed. With most models operating at 7200 RPM, these drives ensure faster data access and improved read/write performance. This speed makes them ideal for applications requiring quick data retrieval, such as database management and data-intensive workloads. Furthermore, the series utilizes a Serial ATA (SATA) interface, which facilitates seamless connectivity and compatibility with a wide range of systems.

The Fujitsu MPE3XXXAT series is built with advanced technologies that enhance durability and longevity. Notably, the drives incorporate advanced error correction algorithms and vibration resistance features, which are crucial for maintaining data integrity over time. This is particularly important in multi-drive environments where vibrations from one drive can affect the performance of others. The drives are also designed with low power consumption in mind, contributing to energy savings without compromising performance.

In terms of data security, the MPE3XXXAT series supports various security features that protect against unauthorized access. These include ATA security features that enable password protection and robust encryption to safeguard sensitive information from potential breaches. This aspect is particularly significant for enterprises that handle confidential data and require stringent security measures.

The operational temperature range of the MPE3XXXAT drives is optimized for demanding environments, allowing them to function effectively in a variety of conditions. Their reliability is backed by an impressive Mean Time Between Failures (MTBF), which signifies their resilience and the manufacturer's commitment to quality.

Overall, the Fujitsu MPE3XXXAT series stands out as a reliable choice for enterprise storage needs. With its blend of high speed, capacity, durability, and security features, it addresses the challenges faced by modern data centers and businesses that require efficient data management solutions. Whether for backup, archival, or active data storage, the MPE3XXXAT series is designed to deliver consistent performance and peace of mind for users.
