WD 10TMVV-11TK7S1, due to PCB failure I replaced it with a donor PCB with same part number(which used to recover another HDD by bypassing USB & wired SATA connector, worked fine in that case) and transplanted U12. The problem is, windows 7 detects the drive correctly , visible the drive without contents in "Computer", after 2 minutes drive disappears from device manager(we can hear a single click at that time). If we disconnected and reconnected the scenario continues. Please help me. Thanks in advance.

Once it showed the volume label & storage usage in "Computer", but after that single clicking sound drive disappeared(after around 2 minutes...

Thanks lindakoft...tried it but nothing wrong with its contacts...

Arent those hard drives using SMARTWARE? U12 change is not solving problem in case its only a PCB failure. Do you have pc3000 ? I recommend to test heads.

Sounds like there are other issues, firmware, likely bad sectors.
How did the native PCB fail? What was wrong with it?

@DRforensic ,SMARTWARE didnt installed in it...I don't have PC3000...

@labtech , somebody else tried to repair the native PCB, I got it in tampered condition. My donor board working fine in another HDD, part number & everything same, after U12 replacement through SATA wiring now its detecting correctly, displays the drive in "Computer" with storage usage information along with the drive letter(530GB free of nine hundred something). If we clicked on that drive to open it, after waiting around 2 minutes drive disappears from device manager.

Thanks.

Mhhh, since native PCB was tampered with, then I can't tell with a lot of certainty what the original problem may have been, but for me, I tend to believe the PCB was not the real/main problem, rather something else, internal, like bad heads, possible firmware, likely bad sectors, etc.

Needs to have better drive control and as is, with wiring, don't think that can be maximized.

Thanks labtech..But the drive detects correctly for a while and the volume label & drive size displayed is ok, so no chance of head failure I think, is it correct? Any firmware update for this model?

95% not.

You are going about this the wrong way.
IF

THEN why would the drive need a firmware update?

Thank you labtech..So ur opinion is head failure...
Anybody having PC3000 here in Kerala state of south India? Pls help..

Did you make an image of that drive?

The partition table or the data the operating system needs to mount the drive and read it might be on a bad sector, so the hard drive loads as normal, then when you click on computer to read the drive, it crashes on a bad sector and the drive becomes unstable...

harddrivespecialist , No, without mount my partition how can I do image?

ShaneWard, So what to do...?

Thanks.

A 2 minute delay before a single click would be consistent with the drive autoparking its heads after an APM idle timeout. That said, I would think that the drive should not disappear from Device Manager when this happens.

Try reading the drive's firmware modules with SeDiv:

I would also examine the SMART report with a tool such as CrystalDiskInfo.

http://crystalmark.info/software/Crysta ... dex-e.html

Look for reallocated, pending, or uncorrectable sectors.

Does the raw value of the SMART Load/Unload Cycle Count increment after each click?
