I know what is IDE. I know what is SATA. But what is PATA??? How can I differentiate a PATA drive, let's say from a SATA drive? What is the physical distinction of a PATA hard drive? (I went on the Net, and they keep saying that PATA is IDE...well, no I am sure it's not physically like IDE...).
Also: Wasn't SATA supposed to have no Master/Slave configuration...so how come some ppl are setting jumpers on their SATA drives to make it Master or Slave (unless it's PATA!! Thanks for help.

I thought PATA hard discs and IDE hard discs were actually the same thing as regards the size, connectors and jumpers of the drives.
I had only recently come accross mention of PATA on some Dell machines.
I am certainly no expert. You say that the net keeps saying PATA is IDE and I had come to that conclusion when working friends modern Dell PCs

The only physical difference between a SATA drive and a PATA drive is the power and data cable connections.
PATA has a 40 pin IDE connection. SATA has 7 pin connector. PATA has a 4 pin molex power connector. SATA has a 15 pin power cable.
IDE refers to the type of interface for the drive. ATA either serial or parallel, refers to the method of transferring data along the cable.
There is no master/slave configuration on SATA drives.
PATA/SATA comparison.

"I know what is IDE. I know what is SATA. But what is PATA???"
After SATA (Serial ATA) drives were introduced, many people started referring to IDE drives as PATA (Parallell ATA). In other words, PATA & IDE are the same thing.
