Hi!
Yesterday my Samsung r780 laptop crashed and when I restarted it, the bios could't detect HDD anymore.
I did a little research and I found out that the HDD doesn't start up (motor doesn't spin).
I look up on the internet and found that it might be broken PCB.
I tried to order a new one or buy same HDD but I could found one.
Can you please help me?
Thank you!
Laptop's HDD:
Samsung
Model: HM641JI
HDD P/N: HM641JI/SCC
Rev. A
F/W: 2AJ10001
PCB Specification:
ZZ REV.7
20100507
C3B 3188
Mercury REV.07
R00

I think you should post in a different section.

If you have a multimeter, we could do a little troubleshooting before you spend any money.

I bought one today. How do I do troubleshooting?
Probably I should do a voltage check, but I don't know where to start.

Disconnect the board from the drive and power it up on its own. Then measure the voltages at the Vcore and Vio test points:
