Drive needs formating after recovered files on it

Hi,

Last week Used Recuva to recover files from an accidently formated drive. I Restored all those files on a 2tb drive. After that I can not acces the drive anymore.

The drive is visisble but when I click to open the drive it says that formating is needed to acces is. The drive was almost full and I am afraid to lose everything on it with a format. I dont have enough space on another drive to do a recovery from this 2tb drive to.

What should and can I do?
