pin 1 on 44-pin 2.5 inch pata hard drives

on 44-pin 2.5 inch pata hard drives, is pin 1 always on the end of the 44-pin array that's closest to the master/slave/cable_select jumpers?

I'd expect it would be the same as on a 3.5 inch drive (we're talking about the humongous ribbon cables, right?) and I would simply refer to the pinless point for my 1 or my 44... but I'm just a kid, so I'm not sure I know what I'm talking about... ???

Aaaah I was thinking of IDE... :o

Excellent pictures of the connector, jumper pinnings, and pin numbering:

For info on the special "Reduced Power Spinup" mode in Western Digital 2.5" drives, see:

RPS mode can be used in external USB drive enclosures and other applications when power is tight.
