Glossary

A

ACCESS – (v) Read, write, or update information on some storage medium, such as a disk. (n) One of these operations.

ACCESS TIME – The interval between the time a request for data is made by the system and the time the data is available from the drive. Access time includes the actual seek time, rotational latency, and command processing overhead time. See also seek, rotational latency, and overhead.

ACTUATOR – Also known as the positioner. The internal mechanism that moves the read/write head to the proper track. The Maxtor actuator consists of a rotary voice coil and the head mounting arms. One end of each head mounting arm attaches to the rotor with the read/write heads attached at the opposite end of each arm. As current is applied to the rotor, it rotates, positioning the heads over the desired cylinder on the media.

ALLOCATION – The process of assigning particular areas of the disk to particular files. See also allocation unit.

ALLOCATION UNIT – An allocation unit, also known as a cluster, is a group of sectors on the disk that can be reserved for the use of a particular file.

AVERAGE SEEK TIME – The average time it takes for the read/write head to move to a specific location. To compute the average seek time, you divide the time it takes to complete a large number of random seeks all over the disk by the number of seeks performed.

B

BACKUP – A copy of a file, directory, or volume on a separate storage device from the original, for the purpose of retrieval in case the original is accidentally erased, damaged, or destroyed.

BAD BLOCK – A block (usually the size of a sector) that cannot reliably hold data because of a media flaw or damaged format markings.

BAD TRACK TABLE – A label affixed to the casing of a hard disk drive that tells which tracks are flawed and cannot hold data. The listing is typed into the low-level formatting program when the drive is being installed.

Because Maxtor disk drive’s defect-management scheme handles all such flaws automatically, there is no need to concern yourself with bad track tables.

BIT – Abbreviation for binary digit. A binary digit may have one of two values—1 or 0. This contrasts with a decimal digit, which may have a value from 0 to 9. A bit is one of the logic 1or logic 0 binary settings that make up a byte of data. See also byte.

BLOCK – A sector or group of sectors.

BPI – Abbreviation for bits per inch. A measure of how densely information is packed on a storage medium. Flux changes per inch is also a term commonly used in describing storage density on a magnetic surface.

BUFFER – An area of RAM reserved for temporary storage of data that is waiting to be sent to a device that is not yet ready to receive it. The data is usually on its way to or from the disk drive or some other peripheral device.

BUS – The part of a chip, circuit board, or interface designed to send and receive data.

BYTE – The basic unit of computer memory, large enough to hold one character of alphanumeric data. Comprised of eight bits. See also bit.

C

CACHE – Random-access memory used as a buffer between the CPU and a hard disk. Information more likely to be read or changed is placed in the cache, where it can be accessed more quickly to speed up general data flow.

ATA specifications

Maxtor ATA drives have played a significant role in the evolution of data storage technology, particularly during the late 20th and early 21st centuries. Known for their reliability and performance, these drives became a popular choice for consumers and businesses alike.

One of the main features of Maxtor ATA (Advanced Technology Attachment) drives is their interface. The ATA standard, which later evolved into the Parallel ATA (PATA) and Serial ATA (SATA) interfaces, allowed for the easy connection of hard drives to computers. This ensured broad compatibility across various systems, making it easier for users to upgrade their storage without facing compatibility issues.

The performance of Maxtor ATA drives was also a notable characteristic. With spinning speeds typically around 5400 RPM and 7200 RPM, these drives provided competitive read and write speeds compared to their contemporaries. The utilization of larger cache memory, often up to 8 MB or more, helped improve data transfer rates, ensuring quick access to files and applications.

Maxtor also deployed various technologies to enhance the reliability and longevity of their drives. One such innovation was the use of Shock Protection technologies, which minimized the risk of data loss due to physical shocks or impacts. This was particularly important for portable storage devices, where movement and jostling are common.

The drives were also designed with data integrity in mind. Maxtor incorporated features like S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) to help predict drive failures by monitoring various parameters. This proactive approach greatly assisted users in taking precautions against data loss.

Capacity-wise, Maxtor ATA drives varied significantly over the years, from a few gigabytes in the early 1990s to several terabytes by the time the brand was phased out. This scalability made Maxtor products suitable for both casual users and enterprises needing to store vast amounts of data.

In conclusion, the Maxtor ATA drives represented a significant step forward in storage technology, combining reliability, performance, and innovation. Their legacy continues to influence modern storage solutions, as many of the underlying principles and technologies have persisted into the current era of data storage. Though the brand is no longer in active development, its impact remains a noteworthy chapter in the history of computing.
