I had a 1Tb external hard disk, it actually doesn't store anything beyond around 380GB, it all started when a kid in our house (not me) unplugged the disk when there was copy-pasting going on (not sure but maybe a 1080p film, around 4-5 GB) since then it hasn't worked properly, ever.

Searching for an online solution, i ran a disk check function on Minitool partition wizard, basically only some beginning sectors are fine, after that every other sector came 'bad', chkdsk didn't find any error in usual check but chkdsk /f /r /x comes to a point at when it says around 80 hours ETA at the step 3 of the process (probably something regarding fixing bad sectors) and works very slowly indeed.

Is there some thing I could do to repair the HDD? I don't remember exact model but i do remember it was from Seagate.

There are different kinds of bad sectors.
Some are hardware bad sectors - physical damage on spinning platters of the drive.
Some are software bad sectors - drive for some reason could not read them and has marked them as bad.

First kind - not possible to fix.
Second kind - sometimes can be fixed.

What is the make/model of the hdd?
There are diagnostic and repair apps that can be run which may address your issue.
WD is data lifeguard, Seagate is seatools.
You could probably re initialize the whole drive if you do not want to preserve it's current contents.
I would not count on the drive as it is today to hold anything you do not care to lose.

it's a
Seagate Expansion 1 TB External HDD - USB 3.0 for PC Laptop, Portable Hard Drive (STEA1000400)
it says it has 3 years of data recovery services, but my hdd is empty so i don't need to recover anything.

I used the HDD Regenerator several times and most of them worked, giving the drive an extra life. But if a new HDD is no longer reliable due to its various mechanical components, imagine a fixed one.
All HDD I had with problems similar to your description were Seagate. Today I don't trust this brand anymore, because part of their business is "recovering data from HDDs" that fail. Ironic, isn't it?
As HDDs haven't evolved much, the program hasn't been updated since 2011, but apparently it's still working. It costs the equivalent of a 1TB external HDD. You can get more information from their website (http://www.dposoft.net/hdd.html)
