Performed no bus error correction. The ATA-1 specification was released in , and was withdrawn in With a maximum of 4 devices on the bus. Using PIO Modes 0, 1, 2, 3, or 4. The ATA-2 specification was released in and was withdrawn in Runs with nS Strobes rising edge to rising edge.
Includes CRC. It uses the same connector as ATA, and adds 1 for analog and 1 for digital audio. The ATA-3 specification was released in and was withdrawn in Runs with nS Strobes rising edge to rising edge , but used both edges of the Strobe producing an effective 60nS Strobe rate. Where nS cycle time is 4 clock periods at 30nS each.
Added CRC checking. The ATA-4 standard was released in Runs with 60nS Strobes rising edge to rising edge , but uses both edges of the Strobe producing an effective 30nS Strobe rate. Where 60nS cycle time is 2 clock periods at 30nS each. The ATA-5 standard was released in Where 40nS cycle time is 2 clock periods at 20nS each. The ATA-6 standard was released in Where 30nS cycle time is 2 clock periods at 15nS each. The ATA-7 standard was released in They are the reason the newer motherboards have only one pin IDE connector.
The two long blue connectors are the memory slots. SCSI is capable of supporting up to 7 or 15 devices. The master is the first or primary, hard drive and the slave is the second, or secondary drive.

This should explain it. Hope it helps. Oh, thank you, that makes sense now. It seems the pin may or may not be absent on some IDE drives, and it doesn't really matter because it never carries any power. It is just for orientation if it is absent based on that link.
That link brought me to another question. Shouldn't this cheap thing power a 2. I was going to buy it but was told it would not be able to power a 2. But if the first 44 IDE pins include power, and the adapter has 44 slots, shouldn't it work fine? I have one of those but mine includes a power brick and SATA cables for powering 3.
For a laptop hard drive, the adapter you show is all you need. The power for the hard drive is through the USB port. This connector was designed to replace the older connectors, pin, pin, etc. This connection type is designed to communicate at much higher speeds than what were possible with the older connection styles.
Shop SATA. Shop eSATA. A less common 4-pin power connector is the 3. This connector is smaller in size than the 5. It can be found mainly on 3. Shop 4-pin power 3.
This is a pin interface that supplies power to a computer's motherboard. It has two rows of 10 pins, with a locking tab that holds it firmly in place after connection. Shop ATX pin. The 3-pin Fan power connector is found on power supplies within a computer case. This connector provides power to cooling fans. Shop 3-pin Fan.
The 4-pin Fan power connector is found on motherboards within a computer case. This connector provides power to cooling fans and is typically used on the fan that cools the CPU.
This connector uses the same power arrangement as the 3-pin connector, therefore, a 3-pin connector can be used on a 4-pin fan. The 4th pin is a sensor that allows the fan to be controlled for speed and may give the ability to turn the fan on or off. If you use a 3-pin connector in a 4-pin slot, you will not be able to control the fan as it will always be powered on. Shop 4-pin Fan. This connector is used for auxiliary power.
