Data Recovery Case File · Formatted & Logical Faults · What "Dead" Leaves Out
Knowing the Model Tells Us the Drive, Not What Happened to It
His enquiry is precise about the hardware and silent about the fault. Recovering data from an old computer where "the hard drive is dead", followed by a careful list of the drive's brand, capacity, interface and speed. A model number identifies the drive exactly and says nothing about why it stopped — and "dead" covers half a dozen entirely different faults, each needing a different first step.
| Media | Laptop hard drive of an earlier generation — reported non-functional; specification supplied without symptom detail |
| Reported situation | Data recovery sought from an old computer · drive described as dead · drive make, capacity, interface and rotational speed supplied · specific failure behaviour not described · contents required |
| Fault class | Undetermined behind a general description — the observable failure mode, not the model, governing the appropriate first step |
| Equipment used | Observable failure behaviour established before any conclusion · power and rotation confirmed by measurement and touch · current draw measured on a controlled bench supply · laminar flow bench inspection where rotation was absent · approach selected by symptom rather than specification |
The decode: why the specification is useful and insufficient
What the model number genuinely gives: everything about the drive as a device. Its interface, its internal design, its firmware family, the donor parts it would need — all of that is known precisely from the specification, and it is worth having.
What it cannot give: what went wrong. Two identical drives can fail in completely different ways, and the model tells us which drive we are looking at, not which fault we are solving.
Why "dead" is the least specific word available: it is what any non-working drive is called, and it spans a range of conditions with nothing in common. The response to each is different, and some of the differences are large.
What "dead" might actually mean — and each points somewhere else. No power and no response: a board or supply fault, electrical work with the mechanism untouched. Powers and spins but is not recognised: a firmware or service-area problem, addressed in the drive's own technological modes. Spins with a repeating sound: a head fault needing donor parts under filtered air. Powers, spins and is recognised but returns nothing: surface degradation, imaged under capped timeouts.
Why the distinction is not academic: the wrong assumption leads to the wrong action. Treating a surface fault as an electrical one wastes time; treating a mechanical fault as anything that involves powering it up risks the surfaces — so establishing which is the whole of the first step.
What settles it, and most of it costs nothing: a few observations. Does anything light up or is there any sound on power? Can rotation be felt through the casing? Does the machine's firmware detect a drive at all? Those three answers place the fault in one of the categories above.
Why this matters for the enquiry itself: the more precisely the behaviour is described, the more useful the first response. "Dead, and here is the model" is a good start that needs one more sentence — what it does, or fails to do, when power is applied.
What must not happen while establishing this: no repeated power-up if there is any sound suggesting a mechanical fault. The safe default, until the category is known, is to stop.
On the bench
Observable failure behaviour was established before any conclusion — a model number identifying the device, its interface, firmware family and donor requirements precisely while indicating nothing of the failure, and "dead" spanning electrical, firmware, mechanical and surface faults that require materially different first steps. Power and rotation were confirmed by measurement and touch, and the approach selected by symptom rather than specification.
The outcome
The failure behaviour established before any conclusion, power and rotation confirmed by measurement, and the approach selected by symptom. Free assessment, one fixed written figure including VAT; where a drive has to be opened, 50% of parts and labour is payable upfront with the balance only on success — otherwise no recovery, no fee. The decode: the model number identifies your drive and not your fault. "Dead" covers an electrical fault, a firmware fault, a head fault and a surface fault — and the response to each is different, so the behaviour is what decides the first step.
Describing a drive that has stopped working
Add what it does when you power it, because that decides the first step and the model number can't. A specification identifies the drive exactly — its interface, its internals, the parts it would need — but says nothing about why it stopped, and "dead" covers several unrelated faults. Note three things: whether anything lights up or makes a sound, whether you can feel rotation through the casing, and whether the machine detects a drive at all. Those place it as an electrical, firmware, mechanical or surface fault, which need different responses. And if there's any sound suggesting a mechanical problem, stop powering it.
