5.3 Host Commands

(16) SMART (X’B0)

This command predicts the occurrence of device failures depending on the subcommand specified in the FR register. If the FR register contains values that are not supported with the command, the Aborted Command error is issued.

Before issuing the command, the host must set the key values in the CL and CH registers (4Fh in the CL register and C2h in the CH register). If the key values are incorrect, the Aborted Command error is issued.

If the failure prediction function is disabled, the device returns the Aborted

Command error to subcommands other than those of the SMART Enable

Operations (with the FR register set to D8h).

If the failure prediction function is enabled, the device collects and updates data on specific items. The values of items whose data is collected and updated by the device in order to predict device failures are hereinafter referred to as attribute values.

•The disk drive has a drive-specific function. When the temperature becomes about -20°C or lower, this function restricts the ENABLE/DISABLE ATTRIBUTE AUTOSAVE function of the SMART function. When it isrestricted, the data is only updated in the memory of the disk drive and notwritten into the system area (temporarily suspended). (When the temperature is about -20°C or higher, the disk drive operates depending on whether the ENABLE/DISABLE ATTRIBUTE AUTOSAVE function is enabled or disabled, and the data in the memory and in the system area are updated simultaneously.)

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.
