Check for the interface that is used to connect it to the motherboard using the IDE cables. If it is a 40 pin or 34 pin cable, then it will be an IDE interface device
EIDE cable uses a 40-pin connector at the end of the cable to interface with the drive.
EIDE
7-pin connector
It depends, ones for hard drive are i think, about 40 pins, an less for the floppy IDE cable Desktop hard drives have "40" pin connectors; however, the actual number of pins is 39. There is one pin missing in the upper row, middle. I believe the reason for this is so the ribbon won't be connected upside down, it can only go one way.
DB-25
4 pin and 6 pin. 6 pin provides power for the external device.
An mpp-1150 interface is used with the Atari computer serial interface that connects to a printer 36-pin Centronics connector.
Notebook's use 2.5 hard drives and they have 44 pin connections 3.5 hard drives used 40 pin connections BUT they make adapters to use either or
40 pins but 39 pin working
PATA stands for Parallel AT Attachement. It typically uses an 80-pin connector (ATA-5 cable) with 40 pins as the signals and the other 40 pins as grounds. Its also uses a 4-pin molex power connector. This drive is identical to the ATA IDE we used to rememeber, nothing changed other than the name. However, with the advent of the SATA drives, we needed change to avoid confusion. The things to rememebr is that PATA uses a wide flat parallel interface cable, 80-pins, 4-pin power cable, whereas, the SATA (Serial AT Attachement) uses a 7-pin interface connector, and a 15-pin power conector. The SATA drives are much faster, lower temperatures and lower voltages. The IDE in the drives are identical as well. It means Integrated Drive Electronics. This is the actual electronics within the drive to make it spin/control the read and write access times.
