Connect your hard disk to a computer. Boot the computer and check whether the hard disk detect or not. If hard disk detected Install a data recovery software like for windows ( Recuva or Undelete Plus ) Remember, the less you work with the drive you want to recover data from, the better. As you read from the drive, you run the risk of exacerbating any damage it may have. The more you write to the drive, the more likely you are to overwrite something you want to recover. Bootable linux distros—many of which have tools like TestDisk pre-installed (among other, more advanced tools)—are the best way to go if you're familiar with the method and if you're interested in recovering entire partitions, or making a non-bootable drive bootable again. If you're just looking for files and you know the drive was in a Windows system or a Mac, a stand-alone app is an easier way to go. you can find original source of this document by clicking here
