My hdd external turned into RAW system!! Help!!!

[rainyew7892]

Well, it started few days ago after I bought a new keyboard for my netbook. Then suddenly, one of my harddisk's partition turned in to RAW and cannot accessed!!! When I clicked and tried to explore in 'My Computer', it said: " K:\ is not accessible. Data error (cyclic redundancy check)."
And when I checked it using disk management, the file system is RAW and its status is healthy....

What should I do?
Is any possible way to turn it back no NTFS and save the data? Cause the data is very important to me... Hellppp!!

And sorry for my bad english...

You can try something like EaseUS ( http://www.easeus.com/landing/raw-drive-recovery.htm?gclid=CL2K1YrL2rUCFQWxnQodKVAADg ) or TestDisk ( http://www.cgsecurity.org/wiki/TestDisk ) to attempt to recover the data. You should seriously consider finding a way to backup the data on all of your drives. If you can add a second external drive then get one and dedicate it as a backup drive.
