ISTM that your drive may have a media or head fault. :frowning:

When your drive powers up, it attempts to load its firmware from a hidden System Area on the platters. If it is unable to do so, then it powers up in safe mode with 0GB capacity.

One thing you could try is to gently remove any oxide from the preamp connections at J1 on the component side of the PCB:

BTW, does your drive spin up?

Hello,

           Yes the drive spins up & one more thing it shows me before BIOS "error auto-sensing hard disk secondary drive 0 , i’ve changed the SATA & Power Cables even i’ve changed the system too. If i replace the PCB Card of the same Hard Drive Model , does this helps ? or any other way for data recovery . i really badly want my data back . please help

ISTM that your drive is beyond DIY repair. You probably need a professional data recovery service. :frowning:

I doubt that the problem is in the PCB. In any case, replacing the PCB will probably not work. This is because the MCU chip at location U5 contains unique drive specific calibration data. You need to transfer these data from patient to donor.

Hello,

           fzabkar , what if i replace the PCB with the same Model & Of same PCB Card Number . ? does this helps ? is there any Western Digital Data Recovery Services Provided In Pakistan ?

You would need to be very lucky with a board swap.

I don’t know of any data recovery service in Pakistan, but if India is OK for you, try Amarbir S Dhillon at www.chandigarhdatarecovery.com
