All of the additional wires in the new cable are ground wires, interleaved with the previously defined wires to reduce the effects of capacitive coupling between neighboring signal wires, reducing crosstalk. Although they are in extremely common use, the terms “master” and “slave” do not actually appear in current versions of the ATA specifications. There are 2 IDE ports on my motherboard. This is what my computer looks like: However, if the computer was booted in some other manner without loading the special utility, the invalid BIOS settings would be used and the drive could either be inaccessible or appear to the operating system to be damaged. All of these low-level details of the mechanical operation of the drive were now handled by the controller on the drive itself. Views Read Edit View history.

If there is a single device on a cable, it should be configured as master. Let me know if that doesn’t make sense and I’ll put a picture up on the blog. AT Attachment Computer storage buses Computer connectors.

I have a EIDE/ATAPI DVD drive. How do I install it?

Initially, the second drive interface was not well defined. In practice, of course, protocol overhead reduces this value.

On the gray connector, note that socket 28 is completely missing, so that pin 28 of the drive attached to the gray connector will be open. Did this solve your problem? For many years, ATA provided the most common and the least expensive interface for this application.

Sorry this didn’t help.

Parallel ATA

All of the additional wires in the new cable are ground wires, interleaved with the previously defined wires to reduce the effects of capacitive coupling between neighboring signal wires, reducing crosstalk. In some systems, a third and fourth motherboard interface was provided, allowing up to eight ATA devices to be attached to the motherboard. The ATA connector specification does not include pins for supplying power to a CF device, so power is inserted into the connector from a separate source.


How satisfied are you with this response? Promote cracked software, or other illegal content Offensive: The bottom row of contacts are the odd-numbered sockets of the connector mating with the odd-numbered pins of the receptacle and attach to the remaining even-numbered conductors of the cable.

This has long been seen as a major advantage of SCSI. The top row of contacts are the even-numbered sockets of the connector mating with the even-numbered pins of the receptacle and attach to every other even-numbered conductor of the cable. The following table shows the names of the versions of the ATA standards and the transfer modes and rates supported by each. Flaming or offending other users Illegal activities: I assume it has prongs, since it’s plugged into what I assume is another 4-holed molex cable, connected to another, connected to another tiny 4-holed plug thing.

The gray center connector omits the connection to pin 28 but connects pin 34 normally, while the black end connector connects both pins 28 and 34 normally. However, most modern devices will report write operations as complete once the data is stored in their onboard cache memory, before the data is written to the slow magnetic storage.

Tech support scams are an industry-wide issue where scammers attempt to trick you into paying for unnecessary technical support services. You are reporting the following post: 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 eidde standard. Follow this lead away from the hard drive. It can’t write anything.

The Information for Your Computer Questions. It is attached normally on the black master drive end and blue motherboard end connectors. 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 SATA 1 port connects to the hard drive. Please help improve this section by adding citations to reliable sources. It specifies provisions in the BIOS of eids personal computer to allow the computer to be bootstrapped from devices such as Zip ztapiJaz drivesSuperDisk LS drives, and similar devices.

The connector is an insulation-displacement connector —in other words, each contact comprises a pair of points which together pierce the insulation of the ribbon cable with such precision that they side a connection to the desired conductor without harming the insulation on the neighboring wires.

Parallel ATA – Wikipedia

It was first introduced with interfaces specific to certain CD-ROM drives such as Mitsumi, Sony or Panasonic drives, [20] and it was common to find early sound cards with two or three separate connectors each designed to match a certain brand of CD-ROM drive. The blue host connector has the socket for pin 34 connected to ground inside the connector but not attached to any conductor of the cable.

Usually an ARMD device is configured earlier in the boot order than the hard drive.
