"It No Longer Powers Up" — Are You Sure?
His enquiry made a confident statement about a device that gives almost no outward sign of anything. An old 2TB internal SATA disk that "no longer powers up. I believe the data to be OK and not corrupted. I'm looking for a quote on how much it would be to get the data from this drive." The belief about the data is probably sound. The statement about power deserves gentle examination, because a bare internal drive has no light, no display and no sound it is obliged to make — so "it doesn't power up" is almost always inferred from "the computer doesn't see it". Those are two genuinely different faults with different costs, and telling them apart takes about ten seconds.
| Media | 2TB internal SATA hard drive — reported as failing to power; contents believed intact |
| Reported situation | Drive reported as not powering up · no detection by host · data believed uncorrupted · no noise or symptom described |
| Fault class | To be distinguished between absence of spin-up and failure to be detected while spinning — different faults with markedly different routes |
| Equipment used | Spin-up confirmed by current signature rather than inference (Atola Insight Forensic) · board and motor assessed where no rotation occurred · service-area assessment where rotation was normal · imaging under strict timeouts |
The decode: what powering up looks like, and why the distinction matters
Why a bare drive tells you almost nothing: internal drives have no indicator lamps. Connected to power, a healthy one spins up — which produces a faint but distinct vibration you can feel through the casing with a fingertip, and usually a soft whirr as it reaches speed, sometimes followed by quiet ticking as the heads calibrate. That is the entire external evidence available. Nothing on the drive announces that it has power, so unless somebody deliberately felt for that vibration, "it doesn't power up" is a conclusion drawn from the computer's silence rather than an observation of the drive.
Why the two are different faults: a drive that does not spin at all has a power-side or motor problem — a failed board, a dead motor, a seized spindle. A drive that spins normally and is not detected has completed the mechanical part and is failing later: head calibration, or the reserved firmware region that must be read before it can identify itself. Those need different work, carry different costs and have different prospects, and they present identically to anyone watching a computer that shows nothing.
The ten-second test: connect power only, rest a fingertip on the metal casing, and feel. A drive that is spinning is unmistakable once you know to look for it, and reporting which it is transforms an enquiry from "it doesn't work" into something a bench can plan around. Listening matters too — a beep, a click or a squeal each means something specific, and silence-plus-stillness means something else again.
Why his belief about the data is probably right: both of those faults leave the platters untouched. Neither a failed board nor a firmware-area problem alters what is written, which is why a drive that cannot be reached is so often a drive whose contents are entirely intact. His instinct is sound.
What not to do while establishing it: repeatedly power-cycling to see whether it catches, and — on an old drive that has sat unused — treating the first power-up casually. After long storage the next spin-up is the most demanding moment in a drive's life, so it is worth making that attempt count rather than spending it on a test.
On the bench
Spin-up was confirmed by current signature rather than inferred, using the Atola Insight Forensic to read what the drive actually drew at power-on — which distinguishes a motor that never turns from one that spins normally while the drive fails later, and does so without repeated power cycling. Where no rotation occurred, the board and motor were assessed. Where rotation proved normal, the readiness sequence and service area were assessed instead through the PC-3000 Express in technological mode. Imaging followed under strict timeouts.
The outcome
The actual behaviour established by measurement rather than inference, the correct fault addressed and the contents imaged. 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, for anyone with a bare drive: it has no lights and makes no sound it is obliged to make, so "it doesn't power up" is nearly always inferred from a computer showing nothing — and those are different faults; connect power alone and rest a fingertip on the casing, because a spinning drive produces an unmistakable vibration; a drive that never spins has a board or motor problem, while one that spins and isn't detected is failing at calibration or its firmware region; both leave your data untouched.
Bare drive you think has no power
Check whether it's spinning before you describe it, because a bare drive has no lights and gives you nothing to go on otherwise. Connect power only — no data cable needed — and rest a fingertip on the metal casing. A drive that's spinning produces a distinct faint vibration and usually a soft whirr, sometimes followed by quiet ticking as the heads calibrate. That's the whole test, and it separates two different faults that look identical from the computer's side: a drive that never turns has a board or motor problem, while one that spins normally and still isn't detected is failing later, at head calibration or its own firmware region. Note any beep, click or squeal too, since each means something specific. Both faults leave your data completely intact — and if the drive has been unused for years, make the first power-up count rather than repeating it.
