My drive failed few days ago. Still under warranty …
Any way can i get back my data , before im sendig back for replacement?
Symptoms:
SMART error during boot
Another pc did not reconizing the drive
drive spinning up after turn on , the reading head position in the inner center of the disk until get probably the right RPM , then the reading head jumping to the firs quarter of the disk diameter , the to the outside edge , then sounds its turning off , rpm going down ,and everything starting again…
i can see the reading head , bc this drive have a clear plastic cover…
Any way i can fix this drive by myself? Changing the circuit board maybe ?
I checked the R64 and it measures 0 ohm only… NOt sure why still the hdd is not working. Please help me getting my hard disk alive… Anything else I need to check?
pradhan4u, it appears that the 12V TVS diode has not been able to contain the damage.
A board swap will most likely fail because the Marvell MCU (big “M”, 88i6745-TFJ1) contains unique drive specific calibration data. These data would need to be transferred from patient to donor. There is a vacant location at U12, below the MCU, which is wired for an 8-pin serial EEPROM chip that stores the same data on those versions of the board where the ROM is external to the MCU. Because your drive’s adaptive data are internal to the MCU, I can’t see how you could avoid professional data recovery.
If you wish to check other components, I would focus on the DC-DC converters below the motor controller chip. These supply the Vcore (1.2V) and Vio (2.5V or 3.3V) voltages for the MCU and SDRAM. Check D1, D2, Q3, Q2, R47, R45.
Joshi_Hun, your drive most probably has a head or media fault.
Try cleaning any oxidation from the 20-pin (?) preamp connection points on the PCB with a soft, white pencil eraser. Otherwise, I can’t see any way for you to recover your data.
very unfortunate on my part… But still is there a way ?
Is there a way to buy the same model hard disc and then swap the logic board out of it to my old one…?
Or what is the best suggestion…? Is there any way out…?? I can’t afford the price demanded by the prof data recovery, its **bleep** expensive, Was hoping that I will get the hard disc alive, but really unfortunate…
pradhan4u, believe me, if I knew how to help you, I would tell the whole world, not just you.
Unfortunately, if what the data recovery people tell me is to be believed, the chances of a replacement PCB working without a ROM transfer is extremely low. The symptom will be that the drive will spin up, but it will click when the MCU attempts to locate the firmware zone on the platters.
If the drive were mine, I would remove the PCB and troubleshoot the DC-DC converters. Unfortunately, even if you do succeed in repairing these onboard power supplies, there is still a real chance that other components may have been damaged.
I have been following this thread for a few days, and have been unsuccessful in getting my drive to work.
It is a model WD5000AAKB-00UKA0 made on 31 Mar 2007.
When I apply power to the drive it makes a “mmmmm-meep” sound 5 times at approx. 2 second intervals.
It will not spin up.
As suggested by others, i have removed the diode at D4 and have bridged the R64 resistor. When that made no difference, I removed D3 and bridged R67… still no difference.
People have been talking about swapping boards, but needing to swap out the chip attached to U12 in order to make it work, but this drive has no chip attached to U12.
mybookisdead, the noise you are hearing *may* be a seized spindle motor bearing. Replacing the motor is a major job. If, OTOH, the failure to spin up is due to stiction, then a little percussive maintenance may dislodge the stuck heads just enough for the motor to overcome the adhesion.
Thank you very much for the amazing amount of information. I have learned a lot about how disk drives work.
It would appear that my drive has a stuck spindle. The sound it makes is very similar to the one at http://datacent.com/hard_drive_sounds.php labeled " Western Digital laptop hard drive with stuck spindle trying to spin up with siren." except there are only two parts to the sound sequence instead of the three in the example.
Before I came here to ask for advice I tried doing the “stiction cure” and “percussive maintenance” but was not successful.
It looks like fixing this drive is just not going to happen. (at least I learned something!) Maybe I’ll just open it up over the weekend and see the internal components up close and personal before disposing of it.
I have 500GB WD my book desktop. This is the bulky old version (with the green light indicator) I bought 4-5 years ago. I rarely use this and use this for backup once a month, but it has all of my important docs in it. Suddenly when I hookup to my PC, it ran autoplay but then its not responding. It makes sound like “rrrrr” (not clicking), but thats about it.
Can anyone tell me what causes it and how to fix it?
