Seagate backup drive not working.

My K drive where i store most of my digital Media started becoming unaccessible after a few days of me not using it. I looked for tools to try and recover the data since windows simply wan't to format I decided to look in to recovery options. I tried Recuva from piriform and although it said it scanned a large number of files it said nothing was on the drive which lead me to Testdisk by a friend's recommendation.

I am dealing with a 4TB Seagate backup drive and it only had one main partition. I believe it was NTFS format. My main worry is that In Test disk the disk appears twice. The disk Dev sdc says its in intel partition table and drive K says its in none partition table. if I hit the P key on either of them they both seem to list all the files. i am just trying to figure out how to get the drive navigatable again now.

What should my next steps be? Worst possible solution would be to get a new drive and write the files to a new drive but screenshot feel like this should be recoverable.Is the duplicate listing the problem. Please send what ever support you can my way.

Use /dev/sdc
You should read https://www.cgsecurity.org/testdisk.pdf

I ran a chkdsk just to start and that seems to have dome some things. I then restarted and loaded up testdisk and followed the steps on page 20 in the pdf you linked me.

I am still not sure what the issue is since it says the boot sectors are okay and the back up is okay but it says a valid ntfs boot sector needs to be present still.

Here is my log and the latest screenshot.

UPDATE after a few more restarts and updating windows the drive appears to be functioning.

Thank you very much for your help.

I am not sure what the issue was but now when i check in TESTDISK it says the boot sectors are not identical and its working.
