are ther other tools that may correct the partition error and recover the drive intact?
Yes. And it's from the same people who offer PhotoRec
re: Photrec It has a method to try and recover file content (but the file names are separate and it seems not able to recover that - thus none of the old file names)
For partition recovery, next try
TestDisk. It has a different drive naming convention. I suggest you run it the first WITHOUT the drive plugged in just to see names it assigns your existing drives. Then when you run it with drive plugged in,you can recognized which one it is.
There's a step by step guide
HERE but for a Windows machine you should be able to simply hit Enter each prompt and use default values. DO be sure to verify it recognizes the disk size correctly
before you proceed past that prompt screen.
