Data Recovery Case File · Trust, Practice & Honest Limits · A Question Worth Asking

Would Your Test Be the Same Test?

His enquiry asked something almost nobody asks out loud, and it deserves a straight answer rather than a sales one. An internal 2.5-inch drive he had been told was "damaged beyond a simple data recovery" and would need to go to a lab: "I'm pretty sure that the initial test you offer would be identical to the one I've already had on the drive. Is the cost for a more advanced method of retrieving the data? The chap did say it wasn't impossible to retrieve." He is right to be suspicious of paying twice for the same thing. The answer has three parts, and the first one removes most of the problem: here the assessment is free, so the question of buying the same test twice does not arise at all.

The decode: what a second assessment actually does differently

Why assessments are not all the same test: the phrase covers very different things. A general shop's assessment is usually connect it and observe — does it spin, does it appear, does the filesystem mount. That is a legitimate and useful triage, and it is what most people have had before they arrive here. A recovery bench assessment is a different activity: the drive is brought up on equipment that reads its behaviour electrically rather than through a host, measures what it draws at power-on, reads its internal health and error rates directly, and where necessary addresses it in the manufacturer's own service modes. Those establish which fault it is rather than that there is one, and they produce a category and a figure rather than a recommendation to go elsewhere.

What the previous assessor actually told him, read carefully: two useful things. That the drive is beyond what they can do — an honest statement of a real limit rather than a verdict on the data. And, importantly, that it is not impossible to retrieve. That second remark is worth weight: somebody who had the drive in front of them, with no commercial interest in the outcome, thought it was recoverable. That is a better starting position than most enquiries arrive with.

Where a fee legitimately sits, and where it does not: the distinction he is groping towards. Paying for an assessment that duplicates what has already been established is poor value. Paying for the work — mechanical intervention, donor parts, imaging under supervision — is buying something new. A fee charged before anyone has told you what is wrong is worth questioning; a fixed figure quoted after a free assessment, explicable in terms of the fault, is not.

What he should do to avoid genuine duplication: pass on the previous findings. Whatever the earlier assessor established — noises, behaviour, what was tried — is a starting position rather than something to be discovered again, and it saves time and spares the drive an unnecessary pass. A firm that ignores existing findings and insists on starting from scratch is doing exactly what he is worried about.

The one thing worth doing regardless: stop connecting the drive. If it has already been assessed twice and told to go to a lab, further attempts at home add nothing and cost margin on a drive that is evidently unwell.

On the bench

The prior findings were requested and used as a starting position rather than rediscovered, which avoids exactly the duplication he was concerned about and spares the drive an unnecessary full pass. The assessment was conducted free of charge, so no fee was payable before anything had been established. The drive was brought up on native equipment and its behaviour read electrically rather than through a host — establishing which fault it was rather than that a fault existed — and the fault was characterised and one fixed written figure issued before any chargeable work began.

The outcome

The existing findings built upon, the fault characterised at no cost and a fixed figure issued before commitment. 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, and the answers to his questions: no, they are not the same test — a shop's assessment connects the drive and observes, while a bench assessment reads its behaviour electrically, measures its draw and health directly, and addresses it in service modes to establish which fault it is; the fee, where one exists elsewhere, should buy work rather than a repeat of what is known; and pass on the previous findings, because that is what prevents duplication.
