Parallel ATA (PATA), originally AT Attachment, is an interfacestandard for the connection of storage devices such as hard disk drives, floppy disk drives, and optical disc drives in computers. The standard is maintained by the X3/INCITS committee.[1] It uses the underlying AT Attachment (ATA) and AT Attachment Packet Interface (ATAPI) standards. The Parallel ATA standard is the result of a long history of incremental technical development, which began with the original AT Attachment interface, developed for use in early PC AT equipment. The ATA interface itself evolved in several stages from Western Digital's original Integrated Drive Electronics (IDE) interface. As a result, many near- synonyms for ATA/ATAPI and its previous incarnations are still in common informal use, in particular Extended IDE (EIDE) and Ultra ATA (UATA). After the introduction of Serial ATA (SATA) in 2. ATA was renamed to Parallel ATA, or PATA for short. Parallel ATA cables have a maximum allowable length of 1. Because of this limit, the technology normally appears as an internal computer storage interface. For many years, ATA provided the most common and the least expensive interface for this application. ![]() It has largely been replaced by SATA in newer systems. History and terminology[edit]The standard was originally conceived as the "AT Bus Attachment," officially called "AT Attachment" and abbreviated "ATA"[4][5] because its primary feature was a direct connection to the 1. ISA bus introduced with the IBM PC/AT.[6] The original ATA specifications published by the standards committees use the name "AT Attachment".[7][8][9] The "AT" in the IBM PC/AT referred to "Advanced Technology" so ATA has also been referred to as "Advanced Technology Attachment".[1. When a newer Serial ATA Serial ATA (SATA) was introduced in 2. ATA was renamed to Parallel ATA, or PATA for short.[1. IDE and ATA- 1[edit]. Example of a 1. 99. PC motherboard with nothing built in other than memory, keyboard, processor, cache, realtime clock, and slots. Such basic motherboards could have been outfitted with either the ST- 5. Well now, I have managed to uninstall the NVIDIA ATA driver, and now after several Windows 7 restarts the Device Manager is showing up as “Standard AHCI 1.0 Serial. ATA interface, but usually not both. A single 2- drive ATA interface and a floppy interface was added to this system via the 1. ISA card. The first version of what is now called the ATA/ATAPI interface was developed by Western Digital under the name Integrated Drive Electronics (IDE). Together with Control Data Corporation (the hard drive manufacturer) and Compaq Computer (the initial customer), they developed the connector, the signaling protocols and so on, with the goal of remaining software compatible with the existing ST- 5. The first such drives appeared in Compaq PCs in 1. The term Integrated Drive Electronics refers not just to the connector and interface definition, but also to the fact that the drive controller is integrated into the drive, as opposed to a separate controller on or connected to the motherboard. The interface cards used to connect a parallel ATA drive to, for example, a PCI slot are not drive controllers: they are merely bridges between the host bus and the ATA interface. Since the original ATA interface is essentially just a 1. ISA bus in disguise, the bridge was especially simple in case of an ATA connector being located on an ISA interface card. The integrated controller presented the drive to the host computer as an array of 5. This relieved the mainboard and interface cards in the host computer of the chores of stepping the disk head arm, moving the head arm in and out, and so on, as had to be done with earlier ST- 5. ESDI hard drives. All of these low- level details of the mechanical operation of the drive were now handled by the controller on the drive itself. This also eliminated the need to design a single controller that could handle many different types of drives, since the controller could be unique for the drive. The host need only to ask for a particular sector, or block, to be read or written, and either accept the data from the drive or send the data to it. The interface used by these drives was standardized in 1. ANSI standard X3. AT Attachment Interface for Disk Drives. After later versions of the standard were developed, this became known as "ATA- 1".[1. A short- lived, seldom- used implementation of ATA was created for the IBM XT and similar machines that used the 8- bit version of the ISA bus. It has been referred to as "XT- IDE", "XTA" or "XT Attachment".[2. Second ATA interface[edit]. An Oak Technology. Mozart 1. 6 1. 6- bit ISA sound card, from when the CDROM drive interface had not yet been standardized. This card offers four separate interface connectors for IDE, Panasonic, Mitsumi, and Sony CDROM drives, but only one connector could be used since they all shared the same interface wiring. A Sound. Blaster 3. ISA sound card, from after connector standardization had occurred, with an IDE interface for the CDROM drive. When PC motherboard makers started to include onboard ATA interfaces in place of the earlier ISA plug- in cards, there was usually only one ATA connector on the board, which could support up to two hard drives. At the time, in combination with the floppy drive, this was sufficient for most users. When the CD- ROM was developed, many computers would have been unable to accept these drives if they had been ATA devices, due to already having two hard drives installed. Adding the CD- ROM drive would have required removal of one of the drives.[dubious– discuss]SCSI was available as a CD- ROM expansion option at the time, but devices with SCSI were more expensive than ATA devices due to the need for a smart interface that is capable of bus arbitration. SCSI typically added US$1. SCSI host adapter. The less expensive solution was the addition of a dedicated CD- ROM interface, which was typically included as an expansion option on a sound card. PC motherboards initially did not come with support for more than simple beeps from internal speakers; thus, sound cards (such as the Sound Blaster Pro) were available for use with games, operating system and software event sounds, or to listen to audio CDs. Also, sound cards commonly included a gameport joystick/gamepad port along with interfaces to control a CD- ROM and transmit CD audio to the system. Initially, the second drive interface was not well defined. It was first introduced with interfaces specific to certain CD- ROM drives such as Mitsumi, Sony or Panasonic drives,[2. CD- ROM drive. This evolved into the standard ATA interface for ease of cross- compatibility, though the sound card ATA interface still usually supported only a single CD- ROM and not hard drives. This second ATA interface on the sound card eventually evolved into the second motherboard ATA interface which was long included as a standard component in all PCs. Called the "primary" and "secondary" ATA interfaces, they were assigned to base addresses 0x. F0 and 0x. 17. 0 on ISA bus systems. EIDE and ATA- 2[edit]In 1. ATA- 1 standard was adopted, Western Digital introduced drives under a newer name, Enhanced IDE (EIDE). These included most of the features of the forthcoming ATA- 2 specification and several additional enhancements. Other manufacturers introduced their own variations of ATA- 1 such as "Fast ATA" and "Fast ATA- 2". The new version of the ANSI standard, AT Attachment Interface with Extensions ATA- 2 (X3. It included most of the features of the manufacturer- specific variants.[2. ATA- 2 also was the first to note that devices other than hard drives could be attached to the interface: 3. Device: Device is a storage peripheral. Traditionally, a device on the ATA interface has been a hard disk drive, but any form of storage device may be placed on the ATA interface provided it adheres to this standard.— AT Attachment Interface with Extensions (ATA- 2), page 2[2. As mentioned in the previous sections, ATA was originally designed for, and worked only with hard disk drives and devices that could emulate them. The introduction of ATAPI (ATA Packet Interface) by a group called the Small Form Factor committee (SFF) allowed ATA to be used for a variety of other devices that require functions beyond those necessary for hard disk drives. For example, any removable media device needs a "media eject" command, and a way for the host to determine whether the media is present, and these were not provided in the ATA protocol. The Small Form Factor committee approached this problem by defining ATAPI, the "ATA Packet Interface". Download - Update. Star - Update. Star. Download the. free trial version below to get started.
