F11 startup recovery manager mbr corrupted - hdd not detected

Is there a way to detect my hdd and fix sector 0 or mbr?
Here's my ordeal.
After upgrading from ATI2010 to 2011 plus pack with F11 still activated, I decided to create a ATI2011 bootable media to see what was inside on my win7. After browsing the software I did a shutdown. A few minutes later I heard a clicking noise coming from my sata hdd. My win7 screen was stuck at shutting down screen. So I did a manual shutdown and reboot the pc. The screen came up with a dos prompt saying disk error, not detected.
I can hear the armature inside the hdd clicking back and forth. After a few minutes it stopped. When rebooted again, same thing happens.
Still hdd not detected. Searched the net for reason, and someone said if sector 0 is missing, which I think is where Acronis F11 over written the mbr, the hdd arm would swing back and forth trying to find sector 0. I don't know if that is correct.
I concluded that might be the case. And that Acronis Startup and Recovery Manager has made my hdd a door stopper and all my data unrecoverable. I have tried to detect it using an external usb to sata adapter and slaving it as a second drive. No success. Can't get hdd detected.
Are there other solution to get pc to detect it again, so I can backup the data?
Acronis 2011 has been a nightmare.
