    Ok, got a question for ya's..

    I have 3 HD's in my computer. 2 are the same make, Western digital 500G.. the 3rd is a Toshiba 1TB.

    Windows 7 only sees the first drive (boot), and the 1 TB it does not see the 2nd one..
    The bios sees all 3 of them, with 2 with names like W0003AJC and W000A2S (not sure if thats the exact names).. but the main difference is the last 3 letter/numbers.

    I have these installed as SATA 1 SATA2 and SATA4. Is there a jumper on the HD's that I need to set so that Windows sees the 2nd one as a slave drive or data drive, verses a boot drive?

    Is there anything on the missing drive?
    Have you tried disconnecting the Toshiba and plugging in the 2nd WD in it's place?
    Have you looked for it in diskmgmt.msc?
    There are no jumpers to play with on SATA drives.

    mm well, think i got this figured out.. I need to run the bios every time I change drives.
    This 1TB is the broken one. don't want to do much with it until the new drive comes in and I can copy stuff over.. Then the 2nd drive will be gone back to a backup drive, just in case.. Took me the long way around the problem and the want for all 3 drives to work at the same time..

    Decided to upgrade the mother board. This one is from 2008. Time for a new one.

    Thanks for the replies.
