Shabby disc with MS project file

[IngiAntonsson]

Hi guys. I have an old scratched disc which contains corrupt MS project file 2000. The effect of the whole project or just part of it. I want to clean the disk from scratch, but I'm afraid the project is lost or I have to completely rebuild.
Secondly the project does not appear when I launch this .mpp file. How do I repair ms project file?
