I had Paragon partition manager move my 1TB system partition on my 2TB drive to the second half of the disk. After 3 hours of doing its work, near the very end it reported a bad sector and froze, so I restarted the computer. My partition was gone. I've now installed a temporary Windows XP installation on a different HDD to try and recover my 2TB one. I've ran testdisk which rewrote the partition tables so now at least there is the good old 1TB partition with a drive letter but it's marked as unformatted and the filesystem is damaged so its inaccessible. I don't want to format it because I'll then lose my files. How do I remedy this situation? I have over 200 GB worth of irreplaceable stuff on that drive.
