Welcome to TechSpot

Take that HD out and insert it (set as a slave-drive) in another computer.
Copy the known 7GB data of that HD onto another HD.
Then re-partition the disk in 2 x 35GB and fully format it in NTFS.
If the 63GB unknown data is corrupt, but the 7GB data is still OK but perhaps inaccessible, have a look at www.dposoft.com for their HDD-Regenerator program.
The best there is....
