He Has Convicted Himself on a Word That Describes Two Completely Different Actions

The last case in this collection is about a sentence someone wrote about himself. An external drive with a problem, where he "tried opening" it, and then "as I researched more, I shouldn't have opened the case because the dust would damage the drive" — and so, "now I'm cross with myself." Before any of that stands, one thing needs establishing: an external drive has two cases, and opening one of them is what everybody does.

The decode: five things this case establishes, at the close of a collection

The first — the word case describes two different objects, and he has not said which he opened. An external drive is a plastic or metal shell containing an ordinary drive, and that drive has its own sealed metal body. Opening the outer shell is routine, harmless and extremely common — it is how anyone gets a drive out of a failed enclosure, and a great many of the drives that arrive here have been through exactly that. Opening the inner body is the one the warnings are about. His sentence covers both, and the more likely of the two by a wide margin is the harmless one.

The second — the material he found was almost certainly written about the other action. Warnings about dust and contamination concern the sealed assembly, where heads fly above the surface at a height smaller than a particle of household dust. He read something accurate and applied it to himself without checking that it described what he did. That is the ordinary way research goes wrong: not by finding poor information, but by matching correct information to the wrong situation.

The third — even on the harsher reading, opening is not the moment of damage. Suppose he did open the sealed body. Particles that settle on a stationary platter do nothing at all. Harm requires the drive to be running: the platters must spin and the heads must fly for contamination to be dragged into contact. A drive opened briefly in ordinary room air and then left alone is frequently recoverable, and the decisive question is not whether it was opened but whether it was powered afterwards. He does not say that he powered it — and by his own account, what he did next was read.

The fourth — the sequence he describes is better than most. He attempted something reasonable, then educated himself, then stopped, then asked. The far commoner sequence is to attempt something, get no result, attempt it again, and keep going until nothing works. Learning mid-way and halting is precisely the behaviour that preserves drives, and he is treating it as evidence against himself.

The fifth, and it is what the self-reproach actually costs. People who feel they have ruined something often delay asking, or do not ask at all. The drives that arrive in the worst condition are rarely the ones whose owners made a mistake — they are the ones whose owners kept trying. Feeling cross with himself is the sentiment most likely to have kept this drive in a drawer, and he sent the enquiry anyway, which is the part worth crediting.

The principle, for the last file in this collection: every case here has turned on what a single observation establishes, and this one turns on an observation someone made about himself. His own account of his own action is ambiguous between something ordinary and something serious, and he has resolved that ambiguity against himself without noticing there was one. The discipline this collection has been describing — ask what was actually observed, what was inferred from it, and whether the reading is the only one available — is not reserved for reports from other people. It applies just as much to the account you give of yourself, and that is the version most people never think to question.

On the bench

The extent of the opening was established before any consequence was assumed — an external unit comprising a shell around a drive with its own sealed body, where opening the shell is routine and harmless while contamination warnings concern the sealed assembly, in which heads fly at a height below that of a dust particle. Even there, settled particles on a stationary platter do nothing; harm requires rotation to drag them into contact. No power was applied at any stage, and surfaces were assessed under filtered air.

The outcome

The extent of the opening established before any consequence was assumed, no power applied at any stage, and surfaces assessed under filtered air before rotation. 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, for the last file in this collection: an external drive has two cases and you have not said which you opened. The likelier one is the one everybody opens — and even on the other reading, what causes harm is running it afterwards, which you did not do.
