    Sorry... the last one I bought was $75. Been a while tho.

    It may well be that we will have to explore that dark and treacherous valley of custom-built HDD cables?

    So, anyone care to take a look at the URL's and share their expertise as to the correct pin-outs?

    Also, anyone have a source of the correct gender 50-pin connector?

    I thought I read in a couple of places that Toshiba used them on CD drives.

    I am pretty good with a small soldering iron and just bought a neat little workbench magnifier w/LED's at Harbor Freight today ... and I know how to verify correct pin-outs if I have the correct data ... besides it is all fun!
    Thanks! doc

    The connector part has been touched on in some other threads - part no. here

    CF-28 HD Caddy

    It apparently is same as the ATAPI. Pinout should match the normal notebook HD pinout, the last few aren't used, and I'm not sure how the temp sensors would work out on a homemade plug. JAE will send samples out - I got a pair to comfirm the plugs match.

    Until my soldering skills get a lot better, or I find a suitable breakout board someplace, this is past me. But good luck with it.

    I have followed your suggestion and requested some samples from JAE.

    I have a neat little Antex Precision soldering iron for which I will rig a tiny-tip and use silver solder.

    Since we will soon have a pair of unusable CF-28's here I am highly motivated to cobble together a cable!

    I have found someone who builds cables professionally and who will build me the CF-28 HDD cables if I provide him with the right connector for the motherboard and the correct pin-outs.

    Is the pin-out information on pages 70, 71, & 72 of the CF-28 service manual here: http://amd751.ru/files/cf-28techmanual.pdf correct?
    Thanks! doc

    Dude -

    If you're asking have any of us actually tried pinning out the wiring on one of these connectors and compared that to the MFR's schematic, then no, not bloody likely. Evidently you simply don't understand what is involved - the header connector is SMD with a solder terminal spacing of .5mm - this translates to approx. 0.018" from center to center of each pin; the connector is shrouded, making it very difficult to touch just one pin at a time. Now... If I had one of the correct connectors to use as a template, I sure wouldn't be spending time doing that tedious kind of pinout work trying to make another for testing... I'd just use the known good one I have.

    OK, permit me to rephrase my question ...

    Is there any reason to believe that the pin-outs for the HDD-to-CF-28 motherboard connector might vary from the Service Manual or between the 600, 800, and 1GHz models?

    The guy who will build these does so professionally and does not see this as an unusual challenge. I take him at his word. Besides, all I will be out is the free sample connectors! :-)
    Thanks! doc
