It doesn't spin up. It's really dead. Suddenly, without warning. No noise or anything. The computer shops can do nothing with it. Strangely enough it happened with what seemed like a very orderly shutdown from Task Manager at a time when the system wasn't discernibly stressed or troubled. The shutdown was almost done when an Windows page comes up saying serious error, check your drivers, BIOS, and hard disk space. Then it goes into Operating system launch failed or something.
A drive that doesn't spin up, or sound as if it is trying to spin, will most probably have a dead PCB. In most cases this should cost you US$50 at most. Sometimes there may even be a zero cost DIY solution.
Can you upload a photo of the component side of the PCB?
If you're not comfortable with those DIY steps on how to revive your hard drive then your best option is to consult those professional data service providers. There is also a company called WeRecoverData.com in your area, they provide free consultation and evaluation on how to recover your important files since your drive is already inaccessible by an average user.
In my personal experiences, the lost or inaccessible emails, documents or videos often can be restored back from a hard drive or memory card by applying some data recovery tools, like Recuva, 4Card Recovery, Power Data Recovery, TestDisk and more.
No matter which one you prefer to use, you’d better scan your drive thoroughly and finds much more wanted data back.
Note: No matter what you’ve done to your drive data this time, I hope you can learn a lesson to back up all wanted data on different drives next time.
I will back up soon. Any suggestions on backup software? I've grabbed some on giveaways--Nero, Ocster, SuperEasy, EaseUS Todo Backup, Farstone RestoreIT, and Paragon Backup & Recovery 14 Compact. But I haven't yet decided which one to use.
