Can anyone tell me what's wrong with this HDD

[MrKingD]

I have a Seagate ultra slim portable drive 2TB. When I was transferring data I accidentally clicked reboot immediately when system prompts automatically update complete. After that the drive stopped working, It's showing up in the device manager, but not disc management. I could only hear and feel it's spinning and clicking. Using 'Seatools' will only halts on scanning for drives.
Eventually I decided to open the drive... I know it's very unprofessional and should be done in a dust free environment, but I did it anyway. I recorded a few seconds video of how the actuator is behaving

Drive has physical issues (bad heads at least) and most likely some media issues, more so now you've opened it and let the it run without the lid on

I agree with pcimage. May still be recoverable, but it will likely cost you more after you opened it.
