Nobody Backs Up the Putting-Right
Her enquiry describes a loss that happened twice and the second one cost more than the first. Photographs overwritten when a family member installed something over them: "I paid to rescue it and it was recovered in jumbled form. I bought a second external drive, spent a year sorting through and ordering photos and videos, then that co"llapsed too. The first recovery worked. What it returned was unnamed and unordered, and the year she spent repairing that was itself irreplaceable work — held, like the photographs before it, on a single drive.
| Media | Second external hard drive holding a manually reorganised photograph and video collection assembled over approximately a year from a prior carved recovery — now failed |
| Reported situation | Original collection overwritten on an external drive · recovery commissioned and completed, output returned without names or folder structure · second external drive purchased · approximately a year spent manually identifying, naming and ordering the recovered material · second drive subsequently failing · no further copy held |
| Fault class | Failure of a sole copy holding both recovered content and the manual reconstruction applied to it |
| Equipment used | Second drive assessed and imaged write-blocked with folder structure preservation prioritised · directory and naming metadata treated as primary deliverable alongside content · original recovery output located as a fallback source · results delivered to two independent destinations |
The decode: why the first recovery came back jumbled, and what she then created
Why the output had no names: where a filesystem's index cannot be rebuilt, files are identified by their own internal signatures and written out — which returns the content and none of the description. Photographs come back as sequentially numbered files, organised by type and date if the metadata survived, in no folders. That is a successful recovery and a poor experience, and it is the trade-off this archive describes repeatedly. Nothing went wrong.
What the year actually produced: not a tidier copy of the same thing. She created new information — which photograph is which, what belongs with what, what each one is called, what order events happened in. That knowledge existed nowhere but in her head until she wrote it into folder names and file names, and at that point it became data. Data that had never been backed up, because nobody thinks of their own organising as a thing that could be lost.
Why that is the point worth making: the photographs were recoverable a second time in principle — they came back once and could come back again. The year of work could not. A carve returns pixels; it does not return the knowledge of whose birthday that was. So the more valuable half of what was on that second drive was the part nobody would have described as data.
What follows practically, and it applies to anybody restoring anything: the moment you start repairing a loss, the repair needs protecting from the start. Not at the end, when it is finished — from the first session. A second copy of the work in progress costs nothing and is the only thing standing between a year of effort and doing it again.
Why this failure is worse than the first: the first was an overwrite by somebody who did not understand what they were doing, which is bad luck. The second was a single drive holding the only copy of a year's work, which is a structural exposure — and it is the one this archive keeps returning to.
What is prioritised in the work now: the folder structure and filenames, explicitly, as a deliverable equal to the content. A recovery of that drive that returned the images again without her organisation would repeat the original outcome and waste the year a second time.
On the bench
The second drive was assessed and imaged write-blocked with folder structure preservation prioritised — the manual organisation representing information created over a year and existing nowhere else, so directory and naming metadata were treated as a primary deliverable alongside content rather than as incidental. The original recovery output was located as a fallback source for content, since images could be re-carved where the organisation could not. Results were delivered to two independent destinations.
The outcome
The folder structure and naming treated as a deliverable in their own right, with the earlier output held as a content fallback and results delivered to two destinations. 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: a carved recovery returns content without names or folders, which is a real outcome and a poor experience. What you built afterwards was new information — which photograph is which, what belongs together — and that is data. Protect the repair from the first session, not the last.
Reorganising a recovery that came back without names
Back up the work as you do it, from the first session rather than when you finish. A recovery that returns files without names or folders is a real outcome rather than a botched one: where the filesystem's index can't be rebuilt, files are identified by their internal signatures and written out, which returns the content and none of the description. But the sorting you then do isn't tidying — it's new information. Which photograph is which, what belongs with what, whose birthday that was. None of that existed anywhere until you wrote it into names and folders, and at that moment it became data with no copy. The pictures could be recovered twice. The knowledge couldn't.
