Fixed removable drive filesystem under Linux but Windows still won't mount it

I initially posted this as an issue on Gihub and was told to post it here.

I have a 4TB Seagate removable drive, whose USB connected has weakened at on-drive connection and eventually repeated disconnect/connect events resulted in the drive being no longer recognized by Windows. I immediately used TestDisk (the best utility even among the non-free ones in my experience) and may have made an incorrect choice, so it failed. I then used TestDisk under Linux, the issue was fixed, and now I have no issue mounting the drive under Linux. However, I still need to mount the drive under Windows and cannot do so.

TestDisk under Windows finds the drive, finds the partition, seems to restore it, but after a reboot Windows still won't recognize it, as if nothing happened.

I posted the error log in a Google Doc at https://j.mp/sg8tdsk and a more detailed (more links) at https://inbonobo.tumblr.com/post/624365 ... -partition

I think that this is a bug, but maybe I'm wrong?

LE: added 3 screenshots, which is maximum

Please specify what you did. Even Rasputin would't be able to foresee what "The issue was fixed" means.

TestDisk under Windows
If you repaired it already using Linux it stays repaired under Windows - no need to run Testdisk again!

Post screenshots of what you did in Testdisk and attach them directly to your posting here using the attachment tab on the bottom of the page so that all your information is here and readable for others in the future.

I rather suspect an user error. 8-)

This was done months ago. As I recall, started Testdisk, chose the disk, then followed default option (EFI/GPT), Analysed, pressed Enter to choose the found partition, Write partition structure to disk, confirm Y, reboot, and from then on Linux mounted the drive without an issue.
If you repaired it already using Linux it stays repaired under Windows - no need to run Testdisk again!
Again, this is not what is happening, which is why I reported this as an issue on GitHub and again here. Following the aforementioned path under Windows has no effect and the drive continues to not be recognized under Windows.

I did not take screenshots in Linux, nor in Windows. I cannot go back in time and take screenshots under Linux. I added the first 3 screenshots to my first post and the last 2 to this one.

Testdisk states in a picture above that the structure is OK.

With your unstable USB connector the obvious solution is to duplicate your drive under Linux either on file level or as a whole to another drive without any physical connection problems.
