The owner of our company had his personal home computer crash last week. Upon examination, the hard drive was not showing up in bios and was not even spinning up...no movement or vibration at all. I did the typical troubleshooting things like putting a new hard drive into the computer to make sure the cable or motherboard or power supply were good (which worked just fine) and then taking the suspect hard drive and placing it in a know good PC, only to find it still won't even spin up.
I found an identical hard drive on Ebay and purchased it. My hope was that the circuit board on the bottom of the hard drive was bad. There are simply 5 screws that need to be removed, and a small data cable in order to replace the circuit board. I got the new hard drive in this morning and verified it worked properly. I then replaced the circuit board on the old drive with the new, know good board. The hard drive still won't even spin up or show up in the bios. So, my guess is that the hard drive motor, or some other internal component is bad. Since I have an identical hard drive that is good, is there even a remote possibility that I could simply replace the disk platters in the bad hard drive into the new drive? The owner doesn't want to spend the $800 - $1000 and send the hard drive off to some clean room and have them try to recover the data on disk platters. So, at this point, since the person is pretty much out of luck and unwilling to spend the big dollars for a professional recovery company, I thought I would give it a try, but I wanted to see if anyone else has ever performed a similar proceedure with any success. Am I just having wishful thinking that disk platters can simply be replaced?
Thanks for any advice.
