Why is my hard drive clicking?

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.

// what it is

What that clicking actually is.

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.

// causes

Why drives start clicking.

A few mechanical faults cause that sound, and most trace back to wear, age or a knock.

01

Failed read/write heads

The heads degrade or fail and can no longer read the platter surface, so the drive keeps retrying.

02

A head crash

The heads have touched the platters — often after a drop — scattering debris that makes things worse with every spin.

03

Seized or stuck parts

A seized motor or stuck heads stop the drive initialising, and it clicks trying to get going.

04

A knock or drop

Physical shock, especially while powered on, is the most common trigger for sudden clicking.

// what to do

What to do — and what not to.

The first rule is simple: stop using the drive. Everything else follows from that.

Do

Switch it off now

Power the drive down and leave it off. Each extra minute running risks turning a recoverable drive into a lost one.

Note what happened

A drop, a power cut, a spill? Tell us — it helps us plan the recovery and source the right donor parts.

Do

Get it to a specialist

Clicking needs head-level work in a clean-air environment, not software. Drop it off or post it to us insured.

×Don't keep power-cycling it or rebooting hoping it'll catch — repeated attempts are the most common cause of permanent loss.
×Don't run recovery software on a clicking drive. It keeps the drive powered and reading, which is exactly what causes more damage.
×Don't freeze the drive. It's an old myth — condensation and contraction damage the platters and heads.
×Don't open the drive yourself. Opening it outside a clean-air environment contaminates the platters in seconds.
// faq

Common questions.

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.
