(44)SET MAX ADDRESS EXT (X’37’): Option (customizing)

•Description

This command limits specifications so that the highest address that can be accessed by users can be specified only in LBA mode.

The address information specified with this command is set in words 1, 54, 57, 58, 60, 61, and 100 to 103 of the IDENTIFY DEVICE command response. If read or write processing is executed for an address that is outside of the new address space, an ID Not Found error occurs.

If the SC register bit is 0 and the value volatile (VV) bit is 1 when this command is executed, the specified values are maintained after a power-on reset. If the VV bit is 0 when the command is executed, the specified values are invalidated during the power-on sequence. If the VV bit is 1, the highest address value is defined as the last value specified. (If the VV bit is not set to 1, the highest address is the default value.)

After a power-on reset is performed, a host can issue the SET MAX ADDRESS (EXT) command only once if the VV bit is 1. If the SET MAX ADDRESS (EXT) command is issued twice or more, an ID Not Found error occurs.

When the SET MAX ADDRESS EXT command is executed, all SET MAX ADDRESS commands are aborted. The address value returns to the origin when the SET MAX ADDRESS EXT command is executed using the address value returned by the READ NATIVE MAX ADDRESS command.

•Error reporting conditions

•

•

This command is issued twice or more in an operation sequence. (ST = 51h, ER = 10h, ID Not Found)

The READ NATIVE MAX ADDRESS EXT command (27h) is not issued immediately before this command (ST = 51h, ER = 04h, Aborted) is issued.

•

•

This command is issued while LBA = 0 (ST = 51h, ER = 04h, Aborted)

The SET MAX ADDRESS command has already been issued.

MHW2060AC, MHW2040AC specifications

The Fujitsu MHW2040AC and MHW2060AC are notable hard disk drives (HDDs) that have been widely used in various computing applications, especially in laptops and compact devices. These models are part of Fujitsu's commitment to providing reliable storage solutions that meet the demands of modern computing.

The MHW2040AC offers a storage capacity of 40 GB, while the MHW2060AC provides a slightly larger capacity at 60 GB. This range of storage makes both models suitable for users looking for dependable space for documents, multimedia files, and software applications. Both drives utilize a 2.5-inch form factor, ideal for mobile computing, as they are lightweight and designed to fit into space-constrained environments.

In terms of performance, both drives operate at a spindle speed of 5400 RPM. This speed strikes a balance between power consumption and performance, making these drives an efficient choice for everyday tasks, such as web browsing and office applications. The drives are equipped with an interface of Ultra ATA/133, which enables faster data transfer rates compared to older models, thereby enhancing overall system responsiveness.

The MHW2040AC and MHW2060AC also incorporate several advanced technologies to bolster their performance and reliability. One such feature is the use of a fluid dynamic bearing (FDB) for the spindle motor, which minimizes noise and vibration, thus improving the overall user experience. Additionally, both drives come with error correction technology that helps maintain data integrity by detecting and correcting errors during read and write operations.

Moreover, these HDDs feature a shock sensor that can detect sudden movements, allowing the drive to park its heads to prevent data loss and hardware damage. This is particularly beneficial in mobile environments where the risks of impact are higher.

Both the MHW2040AC and MHW2060AC are designed with energy-saving features, making them an environmentally responsible choice for energy-conscious consumers. Their low power consumption not only contributes to a reduced carbon footprint but also extends battery life for portable devices.

In summary, the Fujitsu MHW2040AC and MHW2060AC are reliable, efficient, and user-friendly hard disk drives that combine moderate capacities with advanced features designed to enhance performance, ensure data integrity, and extend device longevity. These drives are well-suited for a range of applications, making them a solid choice for users seeking dependable storage solutions.
