    Hard Drive Not Detected


    Hello all,

    I've got an issue during post installation. One of my hard drive is never given a drive letter, but it does show up as a possible install drive during setup.

    I always have to go into Drive Management and assign that drive a letter (and moving my DVD drive down a letter to keep the letters in order).

    Under Drive Management the drive has the Properties (System, Active, Primary Partition), so I'm wondering if that is the issue.

    Is there a way to change Drive Properties (if that is the case)?

    Thanks

    For some reason, maybe to prevent people from messing up their system, Windows sometimes hides the "system" partition. The system partition is the partition that holds the files necessary to boot (which is also why it is set "active"). If your system partition is only 100MB you might as well leave it alone. Do not assign it a drive letter.

    In my case Windows XP is on the system drive. but once I assigned it a letter in disk management, all is fine.

    Yes. By installing/moving the boot manager to another partition and setting that new partition as active. You could use the bcdboot and diskpart tools for that (both are included in Windows and on the recovery/install discs).

    What you may be detecting is the OEM restore partition. This will house the factory backup file if you use the OEM restore program (for example PC Angel). You will only be able to alter the partition using the advanced repair options when booting from the Windows 7 DVD.

    Doubtful since this is a homemade system with store bought drives.

    Did you attempt this or not? Do you understand it?
