Probably, the new operating system cannot recognize your Seagate external hard drive. You can connect the Seagate external hard drive to another computer to copy data to another device. If the problem still exists, you might need to perform data recovery. You can free download the data recovery software: http://www.icare-recovery.com/seagate-recovery/seagate-external-cannot-be-recognized.html
Switch off and on your Freeagent, that should cause a driver to be loaded. If no change reset your Laptop. You should also upgrade to Windows 10, since WINDOWS 7 IS NO LONGER SUPPORTED.
First off....8 is not an upgrade, Win 10 is an upgrade.
Forget looking for any data from your old hard drive as it has been written over and you cannot retrieve it any longer. Just obtain a copy of Windows Ten or pay for a new updated disc. Let Windows format the hard drive and install itself for you.
Go to the Seagate site and under support you should find some tools to check the condition of your hard drive. If your drive is old it may not be able to deliver the movie fast enough.
Are you able to see the drive here in disk management?
If so you can right click on the drive and create a new volume and take all the default setting. I’m happy to help further over the phone at https://www.6ya.com/expert/joshua_ac64e182ed26f66d
You have an issue. The part number you gave is for a 12V power supply for an external hard drive. Since a typical USB puts out 5V, it cannot possibly drive your hard drive. There is a possibly..albeit low...where you can get a plug that plugs into 2 USB ports and provide 10V but I am not sure that will be enough to drive it. If this external unit is already in a case, look for a plug that would accept the power supply pin (pix attached)

Okay the problem could be either with your computer or the external drive the first thing you need to do is try the external drive on another computer a friend's or someone's and see if it shows the files if it does not show the files on an another computer as well as your current computer then I suspect the problem is with the drive this is common especially if these drives have dropped or taking a file or gotten old if the drive is clicking and not spinning that's a big problem if the drive is spinning and you can hear it spin but it's not showing up on the computer there may be a different issue you may need to look towards data recovery for that external drive that's the best I can tell you at this time and based on the information you've given best of luck
Don't know if you still need it but I have one that I pulled from a Seagate backup drive that I just scrapped.
I've listed it on eBay, search for:
Seagate 100FC02 USB/AC ADAPTER INPUT To SATA PCB
The usb port probably needs to be re-attached to the board, it would likely with have to be soldered.
You may also be able to remove the actual drive from the external enclosure, look online for info on that.
if you don't have a backup as a precaution I would do a full back up and get a new hard disk because the one you're referring to might be slowly on his way out
