[not recognized] WD5000BEVT-22ZAT0

Hi,

My HDD is not recognized in BIOS.

I want to tell you the whole story how it is happened. I had around 50Gb files on my desktop and my HDD was 99% full. I moved them all to a new created folder on desktop. After I moved explorer.exe was hanging and crashed. My laptop is directly connected by power supply [I don't have a laptop battery].

I restarted my laptop by unplugging the powersupply, OS (win7) tried to load... very slowly and chkdsk started. I didn't wanted to wait, so I unplugged the power supply again. From that moment computer freezed and even bios couldn't get loaded. I removed the HDD and tried to get my files using an other system, I have a SATA to USB cable but hdd didn't got recognized. The disk is spinning, no weard sounds. But when I unplug the usb cable (power off) I hear a clear "shut down" sound of the motor inside it.

I ordered a new PCB from ebay. same ML, sticker serial + PCB serial. After I swapped the PCB the laptop gives ERROR 0200: Failure Fixed Disk 0. There is no 8 pin smd chip on the PCB that I could transfer, does anyone got cheap diy tips that I can try?

More than likely it is not a PCB issue.
Try MHDD and report if drive IDs correctly.

Check SMART.
Then probably you have to clone it to another HDD and after than recover data from the clone.
