WD 2TB HDD's not recognized by windows 7/8 x64

Hi all,

I have two WD HDD's one is 2TB elements and the other one is 2TB passport.

Both are not recognized by windows 7/8 x64. but works well on XP x86 and windows 7 x86.

I have checked both for bad sectors or faults but both are perfectly OK.

How can it be?
What can i try to make them work?

P.S- I even checked the HDD's with a bran new out of the box VAIO with windows 8 x64 but it also didn't shows.

Thanks,
Guy.

    What motherboard to you have? Some motherboards don't recognize large HDDs...
  2. I'm using a Lenovo X1 i7 win7 x64 fully updated.
    I have tried it on my home laptop Asus UX32VD-DH71 win8 x64
    I even checked it with a new VAIO (out of the box) SVP13215PXB.

    On a Lenovo T420 with win7 x86 and on any XP x86 that i checked it is working perfectly well.

    its not the processor architecture and its not the motherboard especially with a USB drive it doesn't matter what motherboard, the size limitation is dictated by the usb controller its self, software limitations come down to file system - NOT motherboard, boot device maybe a limitation but USB handover is all down to the controller

    your seeing coincidences here

    in device manager are you seeing a WD SES driver missing when the drives are present?

    also - if you plugging them into a desktop machine is it via front USB ports or rear USB ports, if its connecting to a laptop try the other side
  4. Just so you know, x86 is an instruction set architecture. It has nothing to do with bits which today is usually 32 bit or 64 bit.
