    2.5" harddrive adapter issue

    Howdy, Folks!

    I'm workin' on my little carputer, and have a couple old(ish) 2.5" notebook drives that I want to use. I have two of these adapters, but they don't need to be working.

    When I power up the computer, the drive(s) don't even seem to spin up. I know the drives are perfectly functional, so what gives?

    Anyone else had trouble with these adapters? I'm waiting to get my $2.99 multimeter from here (well, looks like they raised the price a bit) to test the leads, but this is such a simple device, I can't imagine it being bad. I've tried both adapters on both drives, together and one at a time, on both drops of my IDE cable. Nada.

    Thanks for any help!

    Is the drive getting power? Are both connectors the right way around (there are three ways of getting this wrong and one way of getting it right if they are not keyed)?

    funny you should mention this. i have the *exact* adapter connected to a toshiba 2.1gig drive. the bios doesn't recognize the drive at all, but i can access it from windows just fine. that is, as long as its connected to house power. while in the car, it doesn't work at all.

    I had problem with them too. They appear to work fine initially, but when I transfer large data, the transfer seem to occur in bursts, with periods of very long waits in between.

    silly that these things should have issues. It's purely a passthru device, no logic, no components even.

    I'll hack up a couple of IDE cables and make my own adapter to see if I can remedy this.

    Thanks for your feedback!

    that's the adapter I bought back in March 2001.. kind of pricy for the part, but it's now over 2 years later and I've never had a problem with it.

    i had the same poblem when i bought an 2.5" adapter like that, i couldn't figure out what it was. I thought i'd fried the harddrive so i flipped over the adapter as a thought that it can't get any worse scenario and low and behold the drive booted up and continues to work fine.
    Just double & triple check that you have it the right way.

    notebook drive pinout

    yeah - I'm a twit!

    After putzing with this for a while last night, I found that it was a combination of things: master/slave/cs jumper , and connecting the thing upside down. My IDE cables are keyed (pin 20 must be missing to use the connector), so I had to remove the 20th pin on the larger side of my adapter. This allowed me to plug it in, and required this bit to be correct. Then, I verified the drive's pinout:



    xxoooooooooooooooooooo ca
    xxooooooooo oooooooooo db

    with a-d being jumpers, 'o' normal IDE pins, and 'x' being the power and ground pins

    For Jumpering:
    all open = Master
    a-b = Slave
    b-d = Cable Select
    c-a and c-d will cause the drive not to spin up

    The way I had it, it was jumpered to not spin up - 'c-d' is how my desktop drive sets 'cable select'.

    Hope this helps others!
