[Not detecting files from External Hard Drive used for windows 10 install]

3 hours ago, Andavari said:

It needs to have a file system, such as NTFS which the drive would've had by default.

Of course there are other recovery tools if you search the Internet which can read and restore from an unformatted or RAW drive without a file system however those are often not freeware.

So there's nothing Recuva can do? 
If i were to format the drive would that make it recoverable or just (as i would suspect) delete all of the info on it?
Thanks alot

Hey, I accidently formatted my drive by installing the windows 10 stuff onto it, when i try to use Recuva to restore these files, it doesn't find most of them - the whole 1.5TB of them
Can anyone help me with how to restore them all? Other programs can detect them but i dont want to spend 70$ just for that. THanks     Looks like this ^
