Yesterday while watching movie on my PC it appeared as black on the screen and stopped working. After restarting the PC it was not responding as the BIOS was unable to recognize the hard disk. It creates an unusual sound while BIOS searches drives.

1. I tried by booting the PC using another hard disk but this HD does not appear in the windows.
2. I also tried to boot using Ubuntu live CD but failed to find my HD on it.

As it is not recognized by BIOS, I can't use data recovery software to recover the data. I'm badly in need of all data in it.
