External hard drive issue

[Pezdel1977]

Hi, I have recently had my Seagate Barracuda Green 2Tb hard drive fail. It comes up with the error saying it needs to be formatted before use. I have tried scanning for errors through windows explorer, at first it started scanning but then stopped and said the dive is unreadable. Now I can't even right-click on the drive, it crashed windows explorer if I do. I have searched through the forums a bit and there seems to be a few ways to try to recover this, and I don't want to go the wrong way and completely lose everything... I have some stuff on that drive which is irreplaceable.
I have tied using Seatools for windows, the scan did nothing after 3 hours.. was still on 0%, and now it can't even find the drive
I tried recover my files v5, but is stuck on a screen saying "scanning for logical drive G:"
Where should I go from here?

Ok update.. just tried Recover my files again.. It found the drive all of a sudden.. have tied this half a dozen times now, and is scanning now. I'll post a reply again with an update

Ok the scan is running... but everything is going to lost files, with jumbled numbers for file names. I'm guessing this could mean the MFT is corrupt?
