Hello to all,
                           Very nice to meet you. I believe you can really help me.
  (Note:SORRY -  Why i write these much is to give the  clear idea about my    
                                                                                                                                         problem).
                                            I've an 1TB HITACHI SATA INTERNAL HDD. But 'm using it as external (put it in an external case,connect via usb). 5 days back it accidently fell from the chair. But the thing is, the hdd didn't hit the ground- before hitting I caught it (at that time it was in running condition). But the hdd is well shaked. After that when I connect it to  my pc/lap,the hdd is running but it is not accessible by the system. After 1 minute system will show either 'not accessible' or 'format drive'. Not showing its properties also (ie: hdd is running but I can't enter to it). A small creepy noise also appear after this incident (this noise occur only when I connect it to pc/lap, other time no unwanted noises). I think the noise is from the board of the hdd or near from it. I tried directly in pc- no effect.  
                   My valuable data, movies & music collection around 600gb is in this hdd. If the files are missing its equal to killing me. So please please please help me with your valuable ideas to come out of this tragedy. I want to 
correct the hdd or recover the files from it. (Another one thing is my pc is IDE not SATA).
