That is what I meant! He has 44 pins - 40 for the IDE and 4 extra for
jumpers

44 pins is the standard for a 2.5" drive. Center to center pin spacing is 2mm.
40 of the pins are the "normal" interface pins. 4 pins are used for power. For
a total of 44 pins (two rows of 22 pins).

In this document, a 4 pin block is next to the 44 pin main connector. It
is used to set master, slave, or cable select on the 2.5" drive.

Here is a picture of a 44 pin drive, with the 4 pin master/slave/CS block on the right.
Total number of pins in this picture is 48 pins (minus the one removed for keying).

*******
40 pins is the standard for a 3.5" drive. Center to center pin spacing is 0.1"
There are no power pins on the 40 pin type. A separate Molex power connector
is used, to bring in +12V and +5V.
