Western Digital 750GB Raptor failing?

How did you get a 750GB Raptor?

Reinstall the controller driver and try again.

Made a mistake, its actually a WD Caviar SE16. Same result if I uninstall it and let it install again.

Run manufacturer hard disk diagnostics.
Run Speedfan also and check their results.

If the drive is still working and you have some important info on it, get it off ASAP.
Once you've ran all of your test and you're sure that it working porperly, you can start storing data on it again. Until then I wouldn't take any chances.

i tried running a test using the WD diagnostics but it couldnt complete, here is the screenshot

In the image its the one which has the smart status displaying FAIL

those are the results im getting from diagnostics, else everything is fine, no bad sectors etc

Dying drive, it happens. Back up what you can, replace and keep going.

hmm ok   at least managed to backup the files
