Assessing Everything Once and Recovering in Order Costs Less Than Deciding Blind
His enquiry sets out a constraint most people are reluctant to state. Five defective external drives holding photographs, some already opened, where he asks for a free assessment and the drives returned, so he can "send them one by one, as I'd not be able to pay for all five straight away." That is a workable plan and the order matters, because assessing all five costs nothing and tells him which to spend on first.
| Media | Five external hard drives of varying condition — casings removed from some; one previously subject to a recovery attempt; photographic content sought across the set |
| Reported situation | Five external drives retained and defective · photographic content sought from all · casings removed from some of the units · one drive previously recovered from onto another · assessment of all five requested · drives to be returned pending individual decisions · recovery to proceed one drive at a time as funds allow |
| Fault class | Multiple independent faults of unestablished type — assessment sequencing determined by content value and cost rather than by fault severity |
| Equipment used | All five assessed together before any recovery was scoped · each addressed directly with imposed timeouts on controlled equipment · current draw measured across the start-up cycle per drive · findings and an indicative figure issued per drive · recovery sequenced by the owner against those findings |
The decode: why assessing all five first is the cheaper route
Why assessment before selection saves money rather than delaying it: it costs nothing and it removes guesswork. Five free assessments produce five figures and five condition reports, and choosing between them is then a decision rather than a gamble.
Why the drives will not be equally expensive: the faults differ. An interface board failure is inexpensive; a mechanical fault requiring parts is not, and nothing about the outside of a drive reveals which it has.
Why that is the crucial point for someone paying in stages: the cheapest may hold the most. Spending first on whichever drive he happens to reach for risks using his budget on the most expensive one.
What else the assessment establishes that helps him choose: what is on each. Where a drive reads well enough, a file listing shows what it holds before he commits.
Why that matters across a collection: duplication is likely. Photographs kept across five drives over years are frequently copies of one another, and one recovery may deliver much of what three drives hold.
Now the detail he mentions in passing, which is significant: some casings have been removed. Removing an outer casing to reach the drive inside is ordinary and harmless — that is a plastic shell, not the sealed drive.
Why the distinction is worth stating plainly: people conflate them. Opening the sealed drive itself is a different matter entirely, and if any of these have been opened that changes their handling and their prospects.
Why the previously recovered drive is worth assessing anyway: partial recoveries are common. A drive recovered from once may hold material the earlier attempt did not reach.
How the drives should travel: individually wrapped and clearly labelled. Five drives moving together are easily confused, and knowing which findings belong to which unit is the whole point.
What must not happen while he decides: no test connections. Powering a defective drive to see whether it still works is the one action that can change the answer.
On the bench
All five were assessed together before any recovery was scoped — assessment being free, so five condition reports and five figures convert selection from a gamble into a decision, particularly since interface faults and mechanical faults differ greatly in cost and are indistinguishable from outside. Where drives read sufficiently, listings establish content and reveal duplication across the set. Findings and an indicative figure were issued per drive.
The outcome
All five assessed together, findings issued per drive, and recovery sequenced by the owner against them. Free assessment, one fixed written figure including VAT per drive; 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: assess all five first, because it costs nothing. Otherwise the first drive you happen to choose may be the most expensive one, and the cheapest may hold most of what you want.
Several failed drives and a limited budget
Send them all for assessment first and recover in the order the findings suggest — it costs nothing, and otherwise you risk spending your budget on whichever drive you happened to reach for. Faults vary enormously in cost and nothing about a drive's exterior reveals which it has. Expect duplication too: photographs kept across several drives over years are often copies. Label each drive individually, and don't test-connect any of them meanwhile.
