Seagate Drive Spins and Stops

I have a Seagate 2TB drive (Model: ST2000DM001 | FW: CC44) which was part of Seagate Backup Plus external drive. The drive spins and stops, the PC doesn't recognize it, I tried using it as an internal drive, the result is same.

I have recorded the sound, here it is:

Is this issue fixable or I just lost everything in the drive?

Examining the sound you provided, I conclude that the drive is physically broken, so only professional recovery services may be able to extract the data from it.

If this would occur while powered via an USB connection, there could of been a chance of the HDD having insufficient power, but since the drive was connected internally, there is no chance of that.
