    Hard drive full capacity not recognized


    Only in Windows 7 at the install screen. Even after a fresh install and adding updates, it won't see it. However, if I plug drive in as slave, xp sp3 will recognize the full capacity. Bios recognizes full capacity and all the partitioning softwares recognize the full 320GB. Ironically, I can only access 137 gb. This makes me wonder about the 48bit LBA. But this can't be the case since everything else sees it, right? Why won't windows 7 see the hard drive's full capacity but other OS, partitioning softwares, and the bios recognize the full 320gb? Trying to install Windows 7 x86 Ultimate.

    Welcome Jaunty!

    I would recommend doing a Google search for 137gb limit. I have found one page that looks promising, 137GB limit on 200GB disk?, but there are loads of them out there!

    Good luck!

    I have done several google searches on this issue. Everything I have read so far relates to a bios/motherboard issue. My problem is not a bios/motherboard issue.

    Usually that problem is caused by a jumper on the drive. Check the documentation of your drive; see if you have the jumpers configured correctly.

    Drive jumpered as cable select. I always jumper drives as cable select, as I am always swapping out drives. For kicks, I did try changing the jumper to master. I also tried other IDE cables, with/without any other drives attached.

    What is the Brand & Model of the HD & of the MB you are trying to install this with. I remember some older MB's had a HD size limit they would accept.
