Drives Stored Together Do Not Fail Together, or in the Same Way

His enquiry describes a pair of drives with a shared history and separate problems. Two 500GB drives unused for around seven years, where "one clicked and ticked, and the other made a number of bleeping sounds", with one machine reporting it cannot read them and another asking for a disk to be inserted. Those are two different faults — the sounds are not interchangeable descriptions of failure, and each drive needs assessing on its own terms.

MediaTwo 500GB hard drives stored unused for approximately seven years — one producing a repeating mechanical sound, the other a tone; neither presenting content to either platform
Reported situationTwo drives unused for about seven years · connected through a drive reader · first drive producing a repeating mechanical sound · second drive producing a tone · Mac reporting it cannot read them · Windows machine detecting connection but requesting a disk be inserted · photographs and videos of sentimental value held
Fault classTwo distinct mechanical faults after extended storage — repeating sound indicating failed positioning, tone indicating stalled rotation; component ageing likely in both

The decode: two sounds, two faults, one shared cause

Why the different sounds matter: people describe any failing drive as clicking, and the distinction is real. A repeating mechanical sound is heads attempting to find their position and failing — a physical action retried because it did not succeed, audible each time.

What the tone on the second drive means instead: a motor energised and struggling to turn. A drive that cannot bring its platters to speed produces a tone rather than the smooth sound of a spin-up, which is a stall rather than a positioning failure.

Why that distinction changes the assessment: one drive is reaching speed and cannot read; the other is not reaching speed at all. The commonest cause of a stall is heads adhered to the platter surface, holding the mechanism — a different intervention from replacing a head assembly that has failed mechanically.

What the two of them share: seven years unpowered. Board components age chemically whether or not a device is used, and equipment that worked when put away frequently does not work when brought out — which is why two drives from the same drawer can both fail on first use.

Why adhesion in particular fits long storage: heads resting against a platter for years in close contact can bond to the surface. Time at rest is precisely the condition that produces it, and it explains a drive that will not turn after a long interval better than any wear explanation.

Why the photographs themselves are unaffected by the years: magnetic recordings are stable for decades. What has aged is the hardware, not the content — so the material is intact and the problem is entirely one of reaching it.

What the two computers were telling him: the same thing in different words. The Mac declining to read and the Windows machine asking for a disk both mean a device is present and returning nothing usable — neither is a fault report, and neither distinguishes the two drives.

Why each drive must be treated as a separate job: different faults, different parts, different prospects. They arrived together and share nothing beyond their storage history, and assessing them as a pair would obscure that one may be considerably more recoverable than the other.

What must not happen: no further attempts on either. On the drive producing a tone especially, each connection applies turning force against whatever is holding the platters — which is the recorded surface itself.

On the bench

Each drive was assessed separately with sounds interpreted as distinct faults — a repeating mechanical sound indicating positioning attempts failing and retrying, whereas a tone indicates a motor energised and unable to rotate, most commonly through head adhesion to the platter surface, which extended storage at rest particularly favours. Board components age chemically irrespective of use, accounting for simultaneous failure on first connection. Inspection ran under the laminar flow bench before any spin attempt, with imaging in separate supervised sessions.

The outcome

Each drive assessed separately, the two sounds read as distinct faults, and both inspected under filtered air before any rotation. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery. The decode: those are two different faults. A repeating sound is positioning failing; a tone is a motor unable to turn, usually heads adhered to the surface — which years at rest particularly encourages. Your photographs have not aged; the hardware has.

Old drives that fail when you bring them out

Stop connecting them, and treat each one as its own job — the sounds tell you they've failed differently. A repeating mechanical sound is heads trying to find position and failing; a tone is a motor energised and unable to turn, which usually means heads have adhered to the platter surface, and years at rest is exactly what causes that. Both drives failing at once isn't coincidence: board components age chemically whether or not equipment is used, so things that worked when stored often don't when retrieved. Your photographs are unaffected, since magnetic recordings are stable for decades. It's the hardware that aged.
