That repetitive click — often called the 'click of death' — almost always means a mechanical problem inside the drive. The good news: your data is usually still there. The bad news: every minute it stays powered on, you risk losing it.
Clicking means physical failure. Powering down immediately, then sending it to a specialist, gives you the best chance of a full recovery.
Inside every hard drive, read/write heads float a hair's breadth above spinning platters. The clicking is those heads failing to find their position and resetting against the limiter, over and over. The platters may still spin perfectly — it's the heads, or the parts that move them, that have failed. Your data is almost always still on the platters; the drive just can't read it.
A few mechanical faults cause that sound, and most trace back to wear, age or a knock.
The heads degrade or fail and can no longer read the platter surface, so the drive keeps retrying.
The heads have touched the platters — often after a drop — scattering debris that makes things worse with every spin.
A seized motor or stuck heads stop the drive initialising, and it clicks trying to get going.
Physical shock, especially while powered on, is the most common trigger for sudden clicking.
The first rule is simple: stop using the drive. Everything else follows from that.
Power the drive down and leave it off. Each extra minute running risks turning a recoverable drive into a lost one.

Clicking needs head-level work in a clean-air environment, not software. Drop it off or post it to us insured.
Quick answers to what people ask most.
Usually, yes. Clicking means a mechanical fault, not erased data — the files are typically intact on the platters. Recovery means repairing or bypassing the failed part in a clean-air environment to read the data off. The key is not running the drive any further before it reaches a specialist.
No. Clicking won't resolve on its own, and every power-on risks a head touching the platter and causing permanent damage. Repeatedly trying it is the single most common way a recoverable drive becomes unrecoverable.
No — it's a myth that does more harm than good. Condensation and thermal contraction can damage the platters and heads. Switch the drive off and send it to a recovery specialist instead.
Single hard drives start at £300 + VAT, with a free diagnostic first and no fix, no fee on most jobs. Clicking drives usually need physical, head-level work, which takes a 50% deposit toward donor parts and bench time.
Switch it off and get it to us. We'll diagnose it free and tell you exactly what's recoverable — most clicking drives still have every file intact.
