Power and Data Cable for 3.5-inch hard disk drive (For Desktop Computer or External Enclosure)
Any desktop computer hard drive has two connectors, one for power cable and other for data cable.
Power cable connects a hard drive PCB (Printed Circuit Board) with computer's power supply.
Data cable connects the hard drive with a computer's motherboard.
Depending on the drive model, it may be
- ATA connectors (other notations : PATA, IDE / EIDE, or Parallel ATA) or
- SATA connectors (Serial ATA or S-ATA interface).
SATA Hard drive connectors (S-ATA)
The wide connector is for the cable to power supply. The smaller one is for data cable to the motherboard.
WARNING: Some SATA connectors must be squeezed to disconnect them.
ATA Hard drive connectors (PATA / Parallel ATA / IDE)
IDE/ATA hard drives can be still found in the old computers. Those are easily identifiable by wide ATA bus cable for data lines and 4-pin peripheral Molex connector for the thick colored wires from power supply (+12 V).
