recover deleted data

You mean from day one that the drive was first used? That's not very likely since some files will have been overwritten by new data but it really depends how much the drive has been written to since new. As files are overwritten several times they become damaged so cannot be recovered intact.

If you need to recover files you can try data recovery software: http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm
