My 500GB Western Digital WD5000KS-00MNB0 hard drive suddenly died. No warnings, no SMART impending failure alerts, nothing. It was working without a hitch the last time I used it. Then I powered on the computer a day later and it simply disappeared from the face of this earth.
It doesn’t show in the BIOS and it doesn’t appear in Windows. It doesn’t work on another rig and it doesn’t even work with an external casing. When I put my ear to the device when powered on with the external casing, there’s no activity going on. The platters don’t turn neither are there any sort of ticks or other noises.
This led me to believe that there’s some issue with the power circuitry as the platters aren’t getting any power. So I took a STAR screwdriver and proceeded to remove the hard drive controller. Here’s what I found: ImageShack Album - 8 images (http://img830.imageshack.us/i/dsc02281r.jpg/)](http://img830.imageshack.us/i/dsc02282f.jpg/)](http://img140.imageshack.us/i/dsc02280ms.jpg/)]
If you look at the pictures, it appears that some logic controller on the circuit board is dead, probably burnt from bad power from a faulty PSU(?) or from overheating. If I can replace the controller board, I should hopefully have my poor baby back in the groove
I am willing to go to any lengths as this 500GB hard drive had all my preciously collected music (~80GB of my best music as I only keep what I listen to and discard the rest), lots of HD and non-HD movies, lots of downloads and lots and lots of photos. Someone please shoot me in the head because I don’t have a backup of any of this data Pros, here’s a question: What are the chances that my data is intact on the platters and retrieveable?
I found a couple of places online that sell the PCB of my WD5000KS-00MNB0. Here are a couple of links: PCB for WD5000KS-00MNB0 00MNBO 2060-701383-001 REV A For Sale and PCB for WD5000KS-00MNB0 500gb 7200rpm SATA Hard Drive - eBay (item 170552024447 end time Nov-11-10 13:33:44 PST)
Should I go ahead and order one and replace it myself? Are there any other factors that need to be looked in? Also, all of the WD5000KS-00MNB0 controller boards I’ve found online have different DCM IDs. Take the ebay one for instance - it mentions DCM: HBACAJAAB while my drive’s DCM is HCHCAJAH. Is it required that the DCM IDs need to be exactly the same? If anyone here has tried this with success do respond here.
Thanks in advance.
