Impossible to mount an external hard drive on mac after bug

Question

I made a mistake by plugging my external WD hard drive with my GoPro link (they look like the same). Everything was working, and, during a file transfer, my hard drive disappeared from my MacBook Pro, then, impossible to mount it.

I bought a new box to put my hard drive, nothing to do. It appears in the Disk utilities, it appears with the Terminal command diskutil list.

I tried diskutil info /dev/disk2 and the result is the following :

Device Identifier:        disk2
   Device Node:              /dev/disk2
   Part of Whole:            disk2
   Device / Media Name:      WDC WD75 00AAVS-00D7B1 Media

   Volume Name:              Not applicable (no file system)

   Mounted:                  Not applicable (no file system)

   File System:              None

   Content (IOContent):      FDisk_partition_scheme
   OS Can Be Installed:      No
   Media Type:               Generic
   Protocol:                 USB
   SMART Status:             Not Supported

   Total Size:               750.2 GB (750156374016 Bytes) (exactly 1465149168 512-Byte-Units)
   Volume Free Space:        Not applicable (no file system)
   Device Block Size:        512 Bytes

   Read-Only Media:          No
   Read-Only Volume:         Not applicable (no file system)
   Ejectable:                Yes

   Whole:                    Yes
   Internal:                 No
   OS 9 Drivers:             No
   Low Level Format:         Not supported

And the command diskutil list disk2 :

/dev/disk2
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *750.2 GB   disk2
   1:             Windows_FAT_32 My Book                 750.2 GB   disk2s1

I don't know what I can do... it's been 6 months I have this problem, I tried everything (everything I found out) but nothing worked. There are all my virtual life inside, and professional one, I would love to recover it.

Thanks by advance and sorry for my English ;)

@Techie007 thank you so much ! It worked very well ! So, here is my solution :

I went on http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step#Run_PhotoRec_executable, downloaded the software PhotoRec, followed the steps (simple, really well explained on the wiki) !

Now, I'm recovering everything. It's written 40 hours left, but for the moment, I already recovered 7000 files ! So good !!!

Thanks a lot one more time !
