Solved Seagate 500gb External Harddrive, Windows 7 Will Not Read?

[Custardx]

I have Windows 7 Home premium 64bit as I recently got a new computer, and to my surprise my seagate external Harddisk did not work. If I go to the Devices section, it is listed as Desktop. I have tried many things such as, rebooting, trying different USB, Assigning A letter to the Expansion and a few others as you will see in my screenshots. Just before I forget my old PC 32bit Windows 7 Ultimate, automatically detected my 500gb Seagate 500gb External Harddisk so I cannot see a problem with the Harddrive or with my computer as it is brand new and fully functioning. Below are my screenshots.

As you can see from these images non of the fixes on the fourm, or on seagate work. If you have any fix please reply to this post as soon as you can, or on the other hand any questions. I will be very grateful.

Sorry about the thumbnail, Not sure what happened there.

SATA or PATA????

Have you tried to remove it from the ext case and installed it into the computer...to check if any of the electronics in the external case failed.
could be something with the usb drivers in the new machine... might try unstalling from the device manager the usb controllers, maybe the composite device then turn the machine off and let windows reinstall 'em again and see if the drive is picked up.
At this point I'd be asking just how important is the data on this HD... I'd even go so far as see if I could put the HD into a friends machine,(or old 'puter), to see if it could be picked up???? Be sure and copy the data off the HD while you continue to trouble shoot the drive.
From experience..... the only drive I've not been able to finally detect ended up as a dead drive, "bfh"
luk to you.....

I think it is SATA as its a pretty new drive no older then 1 year old, and i cant be seeing the electrioncs failing as they worked just before i swapped the EHDD to my new computer. The data on the EHDD is moderately important theres a few things that i wouldn't like to lose but nothing life threatening. The EHDD can be picked up on any 3 machines in my house. Windows XP Professional, Windows 7 32bit PC, Windows 7 32bit laptop. There was no drivers for it as it was built it. They advertised it as "plug nd go".

How do I reset the USB drives?
