External hard drive stuck on Mounting filesystem in Ubuntu

[ytcracker]

Hello,

I have a USB external hard drive which isn't recognized anymore in Windows anymore.

Symptoms:
- In win10, when I connect the drive, the devices icon (you know the one you use to eject your drives) keeps appearing and disappearing in the bottom right corner of the screen. At the same time, when the icon appears and disappears, it makes a sound each time, the sound you hear when a drive is connected in Windows. I tried with a cable I know works, same problem.
- The drive is not in Disk Management, not even unallocated. It's as if it wasn't connected at all to the PC.
- In Ubuntu, the drive appeared in Disks as unallocated. It did not have that issue of constantly appearing and disappearing. I tried to format it with NTFS in Ubuntu's Disks application, at the end of formatting I got an error (can't remember what it was). I tried mounting the drive anyway using the same Disks utility, and since then it's stuck on an endless "Mounting filesysyem" (see screenshots in attachment).

Questions:
- How can I repair the drive so I can use it again?
- When and if repaired, how can I recover the data from the drive which I have quickly formatted? (for information, I tried photorec but it was too slow and it didn't seem to really work; Recuva is not an option since the drive cannot even connect to Windows; I was thinking of trying StellarInfo, what do you think? But for that, I guess the drive should be usable under Windows).

Thank you in advance

I don't know man why... and nobody it seems
Perhaps a defective drive...

Some ideas:
- try another main USB port
- try on another PC
- try plug by SATA if possible
- look for the SMART attributes

Eventually the partition cannot be finished because of bad sectors.

Be careful if you want recover the data...
