We Recovered a Western Digital Hard Drive That Others Couldn’t

Case Study

Drive: WD3200AAJS-40RYA0
Problem: Clicking. Diagnosed by multiple third parties as unrecoverable.

This hard drive has travelled the globe and had been looked at by various data recovery companies, eventually landing on the desk of our data recovery partner in Amsterdam. Our partner then asked us if we were up for a challenge and explained to us that the last data recovery company to look at the drive in Portugal had given up with no success.

Third Party Feedback

We got in contact with the company in Portugal and they explained to us that they had tried mechanical and firmware repair, but both did not overcome the problem.

Booking In

Once the drive was booked into our process, it was clear that the warranty seals had been removed and the top cover had been previously opened. Therefore we needed to take the hard drive straight into our clean room to check for any media damage and also to confirm that the mechanics of the drive had been rebuilt correctly.

Findings

We found no cause for concern in the clean room examination. The drive appeared to be clean and was correctly rebuilt. We replaced the internal heads with a new set as a matter of course and rebuilt the drive and then moved to the next stage of our process. The drive was then powered up on our proprietary equipment and an extensive firmware check and fix process was carried out. Perseverance was the key to overcoming the firmware corruption. It was apparent that a lot of the original firmware had been totally overwritten and a lot of painstaking work was done over the next few weeks to rebuild the firmware to eventually allow the drive to come ready.

Imaging

Once it was established that we could access the data area of the drive, it was put into a block level head map imaging process. This allowed us to control the drive and to further stabilise it by imaging each disk surface individually. Once this process was complete a file extraction was carried out on the image to reveal the original folder and file structure.

Result

The image process was a complete success and resulted in over 190GB of data recovered. A  folder and file structure list was sent to the customer, who acknowledged saying that all the data had been recovered.

Once again we were able to test ourselves against our competition, all be it in Portugal.  In this case the customer was fortunate to seek advice from our data recovery partner in Amsterdam who recommended us. We can’t help but wonder how many people are told that their data is lost for ever, without the thought of getting a second opinion.
