Testdisk might be able to help you. The key word here is might.

TestDisk can

  • Fix partition table, recover deleted partition
  • Recover FAT32 boot sector from its backup
  • Rebuild FAT12/FAT16/FAT32 boot sector
  • Fix FAT tables
  • Rebuild NTFS boot sector
  • Recover NTFS boot sector from its backup
  • Fix MFT using MFT mirror
  • Locate ext2/ext3/ext4 Backup SuperBlock
  • Undelete files from FAT, exFAT, NTFS and ext2 filesystem
  • Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.

Find a LiveCD that contains TestDisk on their LiveCD page

Should I format that disk before proceed? Currently it shows unknown partition – Tachyons Jun 7 '12 at 15:30
    
I have not used TestDisk before but I would not carry on a format as it may make it harder to recover any data. If you are wanting to restore the drive to its prior state to try and recover data then I would try Testdisk from a LiveCD without formatting first. In theory TestDisk might be able to restore the partition(s). – Mokubai Jun 7 '12 at 15:33
    
do not format the disk!! boot your system with a livecd of sorts and run testdisk from there. Make sure the HD you want to recover is unmounted. – Bruno9779 Jun 7 '12 at 16:42
