Congratulations! You got by with it. It has generally been possiblt to replace files on NTFS with files approximately the same size for some time. It has been problematic to create or append to NTFS files. The new drivers are supposed to take care of this.

I would ensure I am fully backed up and run every consistencey check possible on the file system. I never fully trust a system which has been through a recovery.

Enjoy your defense!
