This thing just happened today, I have two HDs, c:17G, D:40G, I was extracting files in d:, and system resource ran out and the machine hung, after I reboot, C: starts to run real slow and making major noises, I think it's physcially damaged. But the data on C: is accessible and can be copied out (17G)

my D:, which I assume is not damaged, has major file structure problem, all 40G of data are not accessible, it has everything I need to function as a normal person, contains digital address book of 150 contacts, and all of my works

I am seeking data recovery software, please lend a hand

any advice is greatly appreciated
