Data Recovery On An Hp 1.0Tb WD10EADS External Hard Drive

The hard drive was dropped on the floor and the data was not accessible. After that incident, when the customer tried to access the hard drive, there was an error reading “the hard drive needs to be formatted. “

Immediately the customer took the hard drive to a local data recovery company in Bellevue WA, but after few attempts the only few files that were recovered ware completely corrupted and inaccessible.
I personally had a look at these recovered files. There were less than 100 documents and pictures and when I tried to access one of this retrieved files, there was an error message that this file is corrupted and will not open.
One of our data recovery partners in Bellevue referred the customer to our lab.
As soon the external hard drive arrived at our lab we completely removed it from the enclosure and did the visual inspection as well as the hardware test.

We noticed after the head test was done that the head #4 was damaged, so before we started the head replacement procedure, we started the cloning procedure with the head #4 disabled.
After the cloning procedure was completed and all sectors ware read, we replaced the heads assembly and started to read the rest of the sectors after enabling the head #4.
The hard drive had about 480 bad sectors, which in my book it was pretty good after all these attempts to recover the data with a bad head after the hard drive was drooped.
Please be aware that dropping the hard drive can create a lot more damage than in this particular case. Most common consequences are stuck or sized spindle motor, damaged heads, scratched media platters.
Now back to our particular case. After cloning all sectors from the Western Digital 1.0Tb WD10EADS to the new destination drive we noticed that every single sector was affected by same type of encryption or a damaged translator.
We started running different utilities but there was no success in retrieving the data at this time.
We did couple more tests and we discovered the root of the problem, which was in the actual controller of the external hard drive.

So we connected the cloned Western Digital hard drive to the external enclosure and after scanning the cloned hard drive for data we were able to recover 100% of the data.
We recovered over 35,000 pictures and videos all accessible with no translation error or any type of corruption.
