Case Study Summary
- Client: Samuel (business owner, Australia)
- Device: DVR internal hard drive
- Problem: Clicking drive with motor stalling caused by failed read and write heads
- Solution: Cleanroom head replacement and controlled imaging
- Outcome: Full recovery of critical surveillance footage
This DVR internal hard drive head failure case study documents how Payam Data Recovery recovered critical surveillance footage from a DVR that stopped functioning after a break-in at a business premises. The DVR contained the only copy of the footage required for insurance and investigation purposes.
The problem: mechanical failure in a DVR hard drive
When the DVR arrived at the lab, the internal hard drive was clicking repeatedly and shutting down. These symptoms are consistent with a failed read and write head assembly.
Hard drive heads operate extremely close to the platter surface. Once they fail, continued power-on attempts can cause permanent platter damage. This type of fault requires physical intervention in a controlled environment.
This DVR internal hard drive head failure case study involved opening the drive inside a cleanroom to prevent contamination during inspection and repair.
DVR internal hard drive head failure case study process
Step by step recovery
- Cleanroom opening and confirmation of head failure
- Initial head replacement using compatible donor parts
- Controlled imaging of accessible data areas
- Second head replacement to stabilise weaker regions
- Verification of required surveillance footage
Multiple head replacements were required to safely image all usable sectors. This approach is common in mechanical failures where head damage progresses during operation.
Recovery results
The recovery was successful. All required surveillance footage was copied and verified.
This DVR internal hard drive head failure case study allowed the client to proceed with insurance and investigation processes without further delay.

Frequently asked questions
Can data be recovered from a clicking DVR hard drive?
In many cases, yes. Clicking usually indicates head failure. Recovery depends on platter condition and must be performed in a cleanroom.
Why must DVR hard drives be opened in a cleanroom?
Dust contamination can permanently damage platters. Cleanroom conditions reduce risk during mechanical repairs.
Is DIY recovery possible for DVR hard drives?
No. Powering on a clicking drive can cause additional platter damage and significantly reduce recovery chances.
How long does DVR hard drive data recovery take?
Turnaround time depends on the service level selected and the severity of mechanical damage.
