Internal hard drive - Read head not working anymore?

Hello,

I am using a WD20EADS internal hard drive (Western Digital Caviar Green 2TB) in a Cooler Master Xcraft enclosure to use it as an external hard drive.

On Thursday night, I put my laptop to sleep by closing the screen but forgot to disconnect and turn off the drive or the enclosure beforehand. This has happened to me before, so I turned off the enclosure with the switch, as usual, which had never caused any problems.

However, that night I had the video player paused on a file that is on the hard drive, and I feel like this caused a problem, probably (yes or no? I'll leave it to you to confirm or deny) because of this the read head was not at rest. Since then, when I try to turn my hard drive back on, you can hear the read head moving and the drive starting up (as usual), but then it eventually stops spinning.

What should I do? Have I correctly identified the cause of my problem? Is the read head dead? Is the only way to recover the data to go through a specialized (and very expensive) company that will do this in a clean room?
Thank you.

    Is it recognized by the disk manager?

      I am on Linux. It sees the file "/dev/sdb", but cannot read it. I think it's simply the disk's electronic circuit that works and allows it to be identified.
      In other words, it is partially recognized, or recognized but not read.

      What type of partition was present on the disk?

      A few gigabytes NTFS partition, and an ext3 partition (Linux file system) that takes up the rest of the 2 TB. It is on this last partition that the paused video file was located. MSDOS partition table.

      Have you checked your partitions with TestDisk?

      Impossible, since the disk cannot be read.
