Registers 1F2h through 1F5h must contain the exact values shown in Table 6-7.These values function as a key. The drive responds by setting the ABRT bit in the Error register if the key is not entered correctly.
To select the drive for which the configuration is to be read, set register 1F6h. For execution of the command to begin, load register 1F7h with F0h.

￿￿￿￿￿￿￿￿4'#&The￿%10(+)74#6+10READ CONFIGURATION command displays the configuration of the drive. Like the SET CONFIGURATION command, this command is secured to prevent accidentally accessing it. To access the READ CONFIGURATION command, you must write the pattern shown in Table 6-7to the Command Block Registers. The first byte, 01h, is a subcode to the extended command code, F0h.

In Table 6-7:

0QVG￿Only the value in address 1F2h of the Command Block Registers is different from the SET CONFIGURATION command.

A 512-byte data field is associated with the READ CONFIGURATION command. A 512-byte read sequence sends this data from the drive to the host. The information in this data field represents the current settings of the configuration parameters. The format of the READ CONFIGURATION command data field is similar to that for the data field of the SET CONFIGURATION command, shown in Table 6-8.

However, in the READ CONFIGURATION command, bytes 0 through 31 of the data field are not KEY information, as they are in the SET CONFIGURATION command. The drive reads these bytes as Maxtor CONFIGURATION, followed by eleven spaces. Users can read the configuration into a buffer, then alter the configuration parameter settings.

D540X-4K specifications

The Maxtor D540X-4K is a notable hard disk drive that has made its mark in the world of computer storage solutions. Launched in the early 2000s, this drive was known for its high capacity and reliable performance, making it a popular choice among consumers and businesses alike.

One of the main features of the D540X-4K is its generous storage capacity. With a range of models available, users could select from configurations starting at 40GB to larger sizes, accommodating a wide variety of storage needs. This capacity was particularly advantageous during an era when digital media was rapidly expanding, allowing users to store everything from documents and photos to videos and applications without running out of space.

The D540X-4K utilizes an IDE (Integrated Drive Electronics) interface, also known as PATA (Parallel ATA), which ensures compatibility with a broad spectrum of computers. This interface was standard at the time, making the drive accessible to a wide user base. The drive also supports ATA-100, providing data transfer rates of up to 100 MB/s, which was impressive for its time.

In terms of performance, the drive operates at a speed of 5400 RPM, which, while not the fastest in comparison to modern solid-state drives, provided a suitable balance of speed and efficiency for the average user’s needs. This rotational speed ensured decent read and write times for everyday applications, making it a reliable option for personal computing.

Another characteristic of the D540X-4K is its advanced data protection features. The drive was equipped with Maxtor's unique Shock Protection Technology, which helps protect the drive’s internal components from damage due to shocks or drops. This feature contributed to increased reliability, especially for users in mobile or high-traffic environments.

The Maxtor D540X-4K also incorporates a Cache Buffer, which enhances performance by temporarily storing frequently accessed data. The cache sizes varied across models, with options of 2MB or more, aiding in quicker data retrieval and overall improved system responsiveness.

In summary, the Maxtor D540X-4K is a hard drive that stands out for its storage capacity, compatibility, and protective features. Even today, it serves as a reminder of the evolution of data storage technologies, as it laid the groundwork for the high-capacity drives we utilize in modern computing. Its legacy continues to influence new technologies while reflecting the needs of the early digital era.
