The Dr.Freeware will rename literally everything so you would need to sift through files recovered in tons of new folders! It's a bit too awkward and specifically is a last resort when no other data or partition recovery program will work. It's actually easier going through the expense of a professional data recovery service rather then the dentist's office this will put you through!
The one thing you can try is a look in the disk management tool to see if the drive's partition is showing in there. It may have ended up "offline" where you would need to restore use in there by clicking on the left square and reassigning a new drive letter to see Windows will then mount the partition on it as a new logical drive.
The image shows how to turn a drive from being online to offline while you would doing the reverse of turning the drive back online and made available once a drive letter is seen. The three windows in the image direct you into the "Control Panel>Administrative Tools>Computer Management>Storage>Disk Management" as seen there.
Once you see the drive is online open up a Windows Explorer or Computer Windows after right clicking on the volume to the right of the square to use the add new drive or change drive letter option to see if the volume has been mounted. If the drive is working normally and hasn't failed on you the partition should become available right away.
