External hard drive wont format can I safe the data

Hello,
I have a sea gate portable hard drive have it about 3 or so months now,
About too days ago a message popped up asking me too scan and fix before I can use it again.
At this stage I could still use it for saving stuff.
But I decided I would scan and fix it as I thought this was a good solution to the problem the stupid hard drive was apparently having lol.
So the scan and fix started was doing this for about 10 mintues when my 2 year old cousin came in and pulled out the wire.

(She also threw it across the room a few hours before this it was working but it started making a screeching beeping noise)

So that was cancelled the hard drive just showed up as like (Local Drive F) it was showing up like it had nothing on it at this point
and it said I didn't have acess to use it.
Then I rebooted the computer and it showed up again and it worked
and everything was on it and the scan and fix box popped up again.
So I tried scanning and fixing again and it
was doing so for a good 2 hours maybe longer and it was about half way through when I checked it.
So I stupidly thought it was a problem with it so I decided to reboot the computer
when I did that everything dissapeared on it again like before.
Then I got a a box pop up telling me to format the drive before you can use it again
so I tried that and it said then windows was unable to format the drive.
I have tried everything the last few days I also tried removing the drive letter
I deleted the current partition and deleted the volume renamed the volume still nothing.
Can anyone help me at all or have any clue what I can do
also is there anyway I could extract the data if the hard drive is knackered.

Thanks I tried to be as detailed as possible
I hope you can help me.
