Clicking or grinding
Repeated mechanical sounds can indicate head, surface, motor or internal positioning damage.
Hard drive data recovery
A failing hard drive should not receive another test run.
DataDoc assesses internal and external HDDs with mechanical, electronic, firmware and logical damage. Clicking, impact and unstable access require a controlled route before the media deteriorates further.
Important: Switch the affected device off. Do not initialise, format, repair or repeatedly restart the storage medium.
Specialist services
Different HDD symptoms require different methods.
A missing drive letter, clicking sound and deleted partition are not the same failure and must not be treated with the same procedure.
Drive not detected
Electronics, firmware, mechanics, enclosure or interface problems can prevent identification.
Logical damage
Deleted partitions, damaged file systems and accidental formatting require write-protected analysis.
Impact damage
After a fall or impact, stop all power-on attempts and protect the drive against further movement.
Controlled process
Clear steps, documented decisions.
The technical route depends on the device, failure mode, data priority and any previous attempts.
- 01
Stop and document
Switch the drive off and record sounds, errors, impact events and previous attempts.
- 02
Technical diagnosis
Electronics, firmware, mechanics and identification are assessed without unnecessary writes.
- 03
Controlled imaging
Where technically possible, sectors are acquired to a separate working medium before reconstruction.
- 04
File reconstruction
Data structures and required files are assessed on the working image against the agreed result.

Frequently asked questions
What you should know before sending a device.
What should I do if a hard drive clicks?
Switch it off immediately and do not reconnect it. Repeated starts can worsen mechanical damage.
Should I run recovery software?
Not when the drive clicks, disconnects, runs slowly or suffered impact. Software can add damaging load to unstable hardware.
Can a formatted hard drive be recovered?
Possibly, depending on overwriting, drive technology, encryption and subsequent use. Stop using the drive immediately.
Can I ship a hard drive from another European country?
International cases can be reviewed. Contact DataDoc before dispatch to agree packaging, carrier and return arrangements.
