Backup drive used on old computer, appears not to be partitioned on new 8.1 computer.

Had an old machine running Win Ultimate 7. Did a completely new build. Bought a new Seagate 3TB and backed up a ton of stuff from the old computer to move to the new one. Backup was verified. All information was/is still there.

Installed in new computer and it just doesn't show up. When going into Disk Management, it's there, but says "unallocated" and when right-clicking, the only options are to make it "a new Simple Volume"?

I'm afraid to choose this for fear it'll format the drive or re-partition it or something. It does this when installed IN the machine, OR when used in a dock plugged into the USB3 port.

HELP!

Just as you suspected a "New Simple Volume" will wreck your existing data. Don't do that!

Does the new 3 TB show up in the BIOS of the new machine?

specs of the old & new system. Im looking for the mothebd make & model #'s to see if they are compatible with 3tb drives. I suspect 1 is not fully.

The old was a gateway fx6803-3. It wrote to, and read from 3tb disk with no previous problems. Back ups were verified to be good.

This is the new build info from the order sheet.

Corsair RM750 750w PSU 1
Intel i7 4770K Boxed 1

===================================

I shouldn't be having any issues.

Is this an internal or external drive?
does the drive still work properly in the old system?
Are you still using win7 on the new system?
Was Windows installed in Uefi mode ?

The old computer has 2 hot swap bays in it. This is where the drive was. The hot swap bays now seem not to work with any drive. I put the old computer back together with a new restored c drive. Supposedly with all the required drivers but I think I'm missing some.

I'm pulling what hair I have left on my head, out with this.
