WD head crash case study explains a Western Digital external hard drive that failed after being dropped while connected to a laptop. The drive was sent from Perth, Western Australia to our Sydney lab, and it contained years of photos and videos that the client wanted back.
Case Study Summary
- Client: David (Perth, Western Australia)
- Device: Western Digital external hard drive
- Problem: Dropped while connected, drive no longer worked
- Faults found: Destroyed heads, USB controller encryption, translator issue causing blank sectors
- Outcome: Over 600,000 files recovered, including 50,000+ photos and 3,000+ videos
WD head crash case study diagnosis
The drive was opened in a dust-free environment and the damage was immediately obvious. The read and write heads were completely destroyed from the impact. With mechanical failures like this, powering the drive on repeatedly can increase the chance of platter damage and reduce the chance of recovery.
Head swap and stabilisation
A head swap was performed using a matching donor drive. This is a delicate process because incorrect handling can scratch the platters and cause additional data loss. Once the head assembly was replaced, the drive was able to spin up and become accessible for controlled recovery work.
USB controller encryption complication
This Western Digital external hard drive used controller encryption. Because of this, the recovery specialist could not simply swap the USB circuit board. Instead, a SATA port was soldered directly onto the original board so the drive could be connected safely to professional recovery equipment (PC-3000) while preserving the original encryption characteristics.
External USB hard drives often use on-board encryption as part of their USB bridge design. For background, see Western Digital’s official website.
Fixing blank sectors by rebuilding the translator
After the drive came to life, some sectors initially appeared blank, showing zero values where data should have been. The specialist addressed this by reading the second level translator, recreating it in specialised software, and refreshing the affected areas so the data could be extracted more reliably.
Recovery results
The recovery was successful. The video states that over 600,000 files were saved, including over 50,000 photos and over 3,000 videos. The client received a file listing and report by email.
- 600,000+ files recovered
- 50,000+ photos recovered

Frequently Asked Questions
My external drive was dropped and stopped working. Should I try plugging it in again?
No. When the read and write heads are damaged, every power on risks scratching the platters and reducing what can be recovered. In this case the heads were completely destroyed by the impact.
What is a head swap?
The damaged read and write heads are replaced with a matching set from a donor drive, in a dust free environment. It is delicate work, because mishandling can scratch the platters and cause further loss.
My external drive is encrypted. Does that stop the recovery?
No, but it rules out the quick approach. This drive used USB controller encryption, so the circuit board could not simply be swapped. A SATA port was soldered directly onto the original board so the drive could be read on professional equipment while preserving the original encryption.
Why did some files come back blank at first?
Some sectors initially read as zeros. The second level translator was read, recreated in specialist software, and the affected areas refreshed so the data could be extracted properly.
How will I know what was recovered?
You receive a complete file list and a video preview before the final payment, so you can check the quality of the recovery first. In this job that covered over 600,000 files, including more than 50,000 photos and 3,000 videos.
What does hard drive recovery cost, and when do I pay?
Every hard drive starts with a free assessment, then a written quote with Economy, Priority and Emergency service levels. Where an attempt fee applies, it is part of the total price: you pay it when you approve the quote, and it covers the data recovery engineer’s time, donor parts and technical work. If the recovery succeeds you pay the balance to reach the total price. If we cannot recover your data you owe nothing more, and the attempt fee is your only cost. Prices include GST. If we recover your data and you pay, return delivery is free, including to New Zealand.
