    Hello Tyler,

    First open Start>Run
    Type diskpart.exe
    Once diskpart is open type as I have written below...

    Type DISKPART> list disk and press enter
    This will give you the disks that are available
    You will find that one of your disk will be stated as OFFLINE

    If that happens check which disk number is that and type as below

    DISKPART> select disk *num* and press enter

    *num*=it is number of the disk

    now after that 

    Type DISKPART> ONLINE DISK and press enter

    Your disk will be activated and shown**
    thats it...

    You can take help here also for more explained instructions

    I hope it helped..

    Hello, did you assemble the computer yourself?  Is this the main drive or a second one?  Did windows 7 recognized the drive with no problem?  If windows 7 recognized the drive and installed there, you should not need to initialized the disk.  If it was a second drive you would have to.  You could try using the seagate tools to analize the drive.


    Does the drive show in disk management or device manager?

    1) Right-click on “My Computer” then Click on “Manage”
     2) Double-click “Disk Management” You will probably see Seagate Disk
     3) Right-click in the left portion of that drive box seagate Disk
     4) Click “Initialize” and “OK” in the next dialog box. Wait  few seconds and it should now say “Online” in the box.
    5) If there is no assigned drive letter, right click on the big space of your seagate hard drive then choose Assign  drive letter or Change Driver Letter and Path
