Primary hard disk not accessible

My main Harddisk has just packed it up. It contains some important information. I have removed the hhd and and installed it in my external casing and using to connect through my usb port.When i try to explore the hhd i get HHD is not accessible. i have used GETBACKDATA by Runtime to recover my data but how can i carry out repairs so i can make this drive accesible without losing my information. This drive i don't think is physically damaged. I was originally cleaning my start up registery and when i tried to reboot windows xp never came to the party.. What are some starting procedures i need to perform to make this drive accessible?

 

I think CRJ posted this recently or another moderator. Interesting info and lots of it. Jazz

Okay thanks for your reply?? is there any other option avalable?

 

If this is a system partition that cannot be accessed in any other way to recover from a fatal registry error, bdub2 found a method that worked in the following thread;
