A Drive With an Unknown History Has to Be Assessed Before It Is Approached
This enquiry is made on a father's behalf and turns on a gap in the record. A damaged drive holding photographs, "sent somewhere else a couple of years ago", held by that provider for nearly two years, and recently retrieved. What matters most is not the two years but the not knowing: whether the drive was opened, powered or worked on changes both the approach and the prospects, and nobody has said.
| Media | Hard drive with reported damage — held by a third-party provider for approximately two years and returned; intervention history unrecorded |
| Reported situation | Hard drive damaged and inaccessible · drive sent to another provider approximately two years previously · drive retained by that provider for the intervening period · drive retrieved by the family · no account given of work performed · photographic content sought · assistance requested |
| Fault class | Original fault unestablished with possible prior intervention — seal integrity, contamination and head condition to be verified before any power is applied |
| Equipment used | Intervention history established by physical inspection before any assumption was made · seal, screw and label condition examined for evidence of opening · no power-up permitted pending inspection · laminar flow bench inspection with platter surfaces assessed for contamination and scoring · current draw measured on a controlled bench supply before any rotation |
The decode: what has to be established, and why it comes first
Why the elapsed time itself costs little: a drive stored unpowered and unopened does not deteriorate meaningfully over two years. Magnetic recording is stable for far longer than that, and the platters almost certainly hold what was written to them.
Why the unknown history costs a great deal: the possibilities are very different. A drive that was never touched is in its original condition; a drive that was opened and spun is potentially damaged in a way nothing can undo.
Why that must be settled before anything else: the approach depends on it. Powering a drive that has been opened and contaminated drives particles into the surfaces at speed, which is the single worst thing that could be done to it now.
How opening is detected: by inspection. Seals, screw heads and labels carry evidence of having been disturbed, and a drive that has been opened rarely conceals it from someone looking for the signs.
What is looked for inside where opening is indicated: contamination and scoring on the platter surfaces. Both are visible under filtered air with the right lighting, and both determine whether the recording survived any spin that followed.
Why a provider holding a drive for two years is not itself alarming: jobs are sometimes set aside pending a decision that never comes. A drive that sat in a drawer awaiting authorisation has had nothing done to it, which is the commonest explanation and the best one.
Why it should still be asked about: the previous provider can answer in one message. Whether the drive was opened, and whether donor parts were fitted, are questions they can settle — and it costs nothing to ask before spending anything.
What the answer changes: if the drive was never opened, this is an ordinary assessment of the original fault. If it was opened, the assessment includes whether the surfaces survived, and the honest prospects differ substantially.
Why the original fault is still unknown: nothing in the account describes a symptom. Damaged covers everything from a board fault to a head failure, and those differ by a wide margin in both cost and outcome.
What must not happen meanwhile: no connecting it to see what it does. Until the drive's history is known, powering it is a decision taken without information — and that is the whole of what this case is about.
On the bench
Intervention history was established by physical inspection before any assumption was made — a drive stored unpowered and unopened not deteriorating meaningfully across two years, magnetic recording remaining stable far longer, whereas a drive opened and subsequently spun may carry contamination driven into the surfaces. Seal, screw and label condition were examined for evidence of opening, with platter surfaces assessed for contamination and scoring under the laminar flow bench. No power-up was permitted pending inspection.
The outcome
Intervention history established by inspection, no powering permitted pending it, and surfaces assessed under filtered air where opening was indicated. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery where the drive is opened. The decode: the two years cost little and the not knowing costs a lot. A drive never opened is in its original condition — one opened and then spun may not be, and powering it now would be a decision made without information.
A drive returned from somewhere else
Ask the previous provider two specific questions before you spend anything: whether the drive was opened, and whether any donor parts were fitted. They can answer in one message, and the answers change both the approach and the honest prospects. Don't connect it meanwhile — if it was opened and contaminated, powering it drives particles into the surfaces at speed, which is the worst thing that could happen to it now. Take reassurance about the interval itself: a drive stored unpowered and unopened doesn't deteriorate meaningfully across a couple of years.
