He Offered Two Details and Both of Them Matter
His enquiry supplies information nobody asked for, with an apology for not knowing whether it is relevant. A drive that will not load his files: "it might be bad sectors or something else, can't know. The disk frame has never been opened and it's not a solid-state disk. I don't know if it matters for the price." Both of those facts matter a great deal — and volunteering them is worth more than the symptom description he was apologising for.

The decode: why each of his two facts changes something
The first — never opened. This is the single most useful thing anybody can say about a mechanical drive. An assembly that has been opened in ordinary air is contaminated, and a drive known to be sealed is handled quite differently from one whose history is unknown: it can be inspected and worked on with the assumption that the interior is as the manufacturer left it.
Why it also affects the figure: a contaminated drive requires surface and particulate assessment before anything else, and carries a materially worse prognosis if debris has been struck. Sealed is cheaper and more likely to succeed, and he was right that it bears on price.
Why saying it unprompted is unusual: most people mention opening only if asked, and some do not mention it at all. Confirming a drive is sealed is a positive assertion rather than the absence of a confession, and it saves an assessment step.
The second — mechanical rather than solid-state. The two device types require opposite handling. A solid-state drive that misbehaves can be connected repeatedly at no physical cost; a mechanical one in a fault state is damaged by every attempt. Knowing which before anything is touched determines the very first instruction given.
Why it also determines the technique entirely: mechanical faults involve heads, motors, surfaces and donor parts. Solid-state faults involve controllers, translation layers and chip-level reading — different equipment, different specialisms, different prospects. Nothing about the two overlaps except the word "drive".
Why his uncertainty about the fault is fine: he says it might be bad regions or might be something else, and that is the correct posture. Diagnosing the fault is what an assessment is for — what he cannot supply from an assessment is history, and history is exactly what he did supply.
So the general point, worth carrying to any enquiry: describe what has happened to the device, not what you think is wrong with it. Whether it was opened, dropped, powered while wet, connected to anything unusual, or worked on by anybody — those are facts only the owner has, and they change the handling before anybody looks at it.
On the bench
Sealed status was accepted and the assembly handled as uncontaminated — a drive opened in ordinary air admitting particulate that is struck on rotation, so confirmed sealed status permits inspection on the assumption the interior is as manufactured and carries a materially better prognosis. Device class was confirmed physically before any handling decision, mechanical and solid-state devices requiring opposite handling: repeated connection being physically free on one and costly on the other.
The outcome
Sealed status accepted, device class confirmed before any handling decision, and error rates measured before any figure. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery. The decode: both of your facts matter. A drive confirmed never opened is handled as uncontaminated and carries better prospects — and mechanical versus solid-state decides the very first instruction, because one is damaged by repeated attempts and the other is not.
What to include in a recovery enquiry
Describe what has happened to the device rather than what you think is wrong with it — diagnosis is what an assessment is for, and history is the thing only you have. Two facts are worth stating every time. Whether the drive has ever been opened: a sealed assembly is handled as uncontaminated and carries materially better prospects, while an opened one needs particulate assessment before anything turns. And whether it's mechanical or solid-state: those require opposite handling, since repeated connection costs nothing physically on one and is damaging on the other. Add anything unusual — dropped, powered while wet, connected to an appliance, worked on by somebody.
