7.Standby is the condition at which the microprocessor is powered, but not the HDA. When the host sends the drive a shutdown command, the drive parks the heads away from the data zone, and spins down to a complete stop.

8.After this time it is safe to move the disk drive

9.Average random seek is defined as the average seek time between random logical block addresses (LBAs).

￿￿￿219'4The Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB AT hard disk drives operate from two supply voltages:

•+12V ±10%

•+5V ±5%

The allowable ripple and noise is 250 mV peak-to-peak for the +12 Volt supply and

150 mV peak-to-peak for the +5 Volt supply. The allowable ripple noise for each voltage is measured at the power supply with the drive not attached to it.

￿￿￿￿￿2QYGTYou￿5GSWGPEKPImay apply the power in any order, or open either the power or power return line with no loss of data or damage to the disk drive. The drive can withstand transient voltages of +10% to -100% from nominal when powering up or down. However, data may be lost in the sector being written at the time of power loss. Also if power voltage dwells in the range around reset (9.2 - 9.7 V at 12 V or 3.4 - 4.0 at 5 V) for several seconds, the drive may disable itself. These voltages are outside expected operational limits. However, they will occur during testing. To avoid this event during the testing of reset limits, increase line voltages in 200 mV increments.

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.
