Western Digital external drive plugged directly to motherboard issue.

[Frieken]

WD external drive power circuit board failed, dissasembled unit and plugged drive directly into computer, the computer recognizes the drive is there but won't let me assign a drive letter without formatting it, I have a lot if info on the drive but I'm afraid if I format the disc I will lose all of my data. Right now it is RAW and says I have no data on the drive. If I format to NSTF will I lose everything or will it now show what I have on it?
