You wont need a screwdriver to recover data or a corrupted partition. You wont need anything but software dedicated to hard disk and data recovery. You probably encountered partition and file system recovery tools built into Windows, namely "checkdisk". Using ckeckdisk can fix partition errors by removing inconsistencies in the file system, but it does not do anything good to your data. Lost files will remain lost, and corrupted data will remain corrupted unless you use software data recovery tools more sophisticated than checkdisk.

Dedicated data recovery tools such as Disk Recovery offered take care of your data first, and repair system structures later. Unlike ckeckdisk, dedicated data recovery software can use a separate hard disk or partition to hold the files and data you recover from the corrupted partition. In particular, Disk Recovery scans the disks and partitions in order to locate data that it considers to be of most importance such as Office documents and digital pictures.

Disk Recovery wont leave you with an inaccessible hard drive or corrupted volumes. It finds and corrects damaged partition tables and corrupted file system structures, repairing logical inconsistencies in the disk structures.

All-in-all, Disk Recovery is a highly regarded data recovery tool.
