    Hi

    Couple of years ago i bought an ide to usb converter cable which i used to convert my internal harddrives into external devices.

    I have an old ATA 2.5" 44pin laptop internal hdd whose pin layout i found here...

    When I see this i got confused as there are so many data pins....... But as its evident the usb has only 4 pins of which 2 are power and the other 2 are data.

    Can some one tell me which two pins should i use if i want to make my own ide to usb conversion device...

    I need this coz
    1. i left my converter cable back in india
    2. i dont need the full length wire and all the other stuff that comes along with a converter that i buy int he market.

    shyam

    Here is the USB pinout - http://pinouts.ws/usb-pinout.html

    It's a bit more complicated than that, though. The IDE interface is for parallel data (all bits present at the same time). Usb is a serial interface, and also requires a protocol to be followed to transfer data - www.usb.com
