deleted partition on freeagent Desk

I stupidly left the external usb drive plugged into the computer that I was reloading after moving all the family photos and files to the external drive.

I then proceeded to delete the partition on both the internal and external drive... will your product be able to get the partition back so i can access the information again?

As far as i can tell the data should all be there, windows just cant see the drive with out the partition in place?

Thanks
