Ooh talk nerdy to me. LOL

I worked through this problem on a couple of laptops from Dell and HP in the last month.
The 2.5" hard drive in most laptops has a connector on it that needs to be removed using a small flat screwdriver. Be careful not to bend any pins.
I found that the easiest way was to drop the drive into a USB enclosure and hook up to an XP system. No muss, no fuss and I don't have to open my bench system (not that it has a case). Copy away to CDs or DVDs and you have a permanent backup.
CompUSA and Fry's both provide the devices you need. Just find a knowledgeable salesperson ...
If you are in the D/FW area, FReepmail me and I will be able to provide assistance.
I got 'this' with the conversion kit. It came with 40 (not 44 IDE standard) pins!.
I found a cable company which should get me the right stuff.
BTW, Fry's referred me to the manufacturer; THEY referred me to Radio Shack, which did not have any idea what I was talking about!
The IDE cable for 3.5" drives is 40 pins, not 44.
The IDE cable for 2.5" drives is 44 pins: the same for as the large form factor, plus two pins for the drive light and two pins for power.
Just ordered one as a back-up solution. Thanks.
I thought of that but I am going the internal route.

The adapter supplied with the initial kit I got is identical but has a power connector. As others pointed out, the pin pitch (spacing) does not match a standard IDE cable. There is no indication on either drive or adapter as to which pin is "pin 1".
I am still researching the problem.

I was thinking they were CLOSE and open.
I have a specimen sitting in front of me that you describe. I have also learned about these issues through a course of events similar to yours.
If you like, ask whatever question you want, I believe I can help.
I meant to say:
I have a specimen sitting in front of me of every item that you describe....
Put it back in a laptop case and hook it up to a network. Then access the harddrive...
The laptop is dead; someone gave a 32-ounce Coke. We saved the HD...that's all.
Pin 1 is found as follows:
Desktop 40-pin IDE ribbon cables will have a red stripe on the Pin 1 side.
A laptop harddrive probably has pin one labeled, but a label is not necessary. Pin 1 is on the jumper side of the drive (which will be the right side if one is facing the pins with label side up).
A laptop-to-desktop IDE adapter will have a power cable dangling from it. This power cable is on the OPPOSITE side of Pin 1.
Line this all up and it will work fine. If there is a problem, it is probably with the jumper settings, which will depend on the desktop computer. As a rule, though, if the laptop drive is connected to the same IDE cable as the CD-ROM, the laptop drive can be left jumperless (primary), since most IDE CD-ROM drives expect to be slave.
find a compatible laptop.
