Do now
- Switch off the hard drive and affected device completely.
- Disconnect USB and power cables from external drives.
- Record the clicking sound and the event preceding it.
- Keep the medium protected against shock and static electricity.
Data loss guidance
Hard drive clicking? Switch it off immediately.
Repeated clicking or clattering may indicate a mechanical or internal control fault. Every further start can put the surface and remaining accessible data at additional risk.
Further attempts may worsen damage or change recoverable data.
Immediate precautions
Protect the remaining options.
Avoid
- Repeatedly starting or reconnecting the hard drive.
- Opening the enclosure or hard drive yourself.
- Running diagnostic, cloning or recovery software.
- Shaking, cooling or heating the drive.
Possible causes
Similar symptoms can have different causes.
A reliable assessment requires examination of the actual medium.
Read/write head damage
Damaged or incorrectly positioned heads can cause typical repeated clicking.
Damaged surface
A fall or continued operation may damage platter tracks and cause further secondary damage.
Firmware or servo-data fault
Internal management or positioning information may prevent the drive from becoming ready.
Electronics and power supply
Faulty components or an unsuitable power supply may cause startup and initialisation problems.
Professional diagnosis
Isolate the fault before reconstructing data.
Storage technology, damage and data priorities determine the route, not a one-size-fits-all software solution.
01 · Record symptoms and history
Noise, falls, power failures, previous damage and attempts are documented.
02 · Check the condition under control
Electronics, startup behaviour and technical identification are assessed without unnecessary writes.
03 · Select an appropriate recovery route
Imaging, firmware access or mechanical measures are planned according to the findings.
04 · Define the result and costs
Before work starts, you receive the prospects, defined recovery objective and binding fixed price.

Frequently asked questions
Hard drive clicking? Switch it off immediately.
What does clicking mean?
Clicking may indicate a mechanical, internal management or electronic fault. Sound alone does not identify a definite cause.
May I connect the clicking drive once more?
No. A drive with repeated clicking should stay switched off because further starts may worsen existing damage.
Will recovery software help a clicking HDD?
If mechanical damage is suspected, further software load is risky. The drive should first be technically assessed.
What does the assessment cost?
Without a follow-up recovery order, technical diagnosis costs €89.00 including VAT. If you accept the fixed-price offer, diagnosis is included in the total and is not charged separately.
Can I send the drive from anywhere in Germany?
Yes. After case registration, you receive a case number and the agreed shipment route to DataDoc in Cologne.
Switch off and have the case assessed.
