ATA (44) internal connector pinout
This connector is mostly used for 2.5 IDE HDD of notebooks and so on. Pins 1-40 are the same as the IDE/ATA 40 pin connector, but the spacing between pins is smaller and they are therefore electronically, but not physically compatible.
Note: Direction is Controller relative Devices (harddisks).
Special Note: Pin 1 is closes to the 4-pin selector. Pin 20 may be missing, this is normal, and allows for cable polarity.
On some motherboards, pin 1 is usually indicated by a Square or Triangle, either on the solder pad, above label, or silkscreen markings.
