Data Recovery Case File · Portable Drives · A Boundary He Can Name
Knowing Exactly When It Last Worked Bounds Everything That Follows
His enquiry supplies a detail most people cannot. A drive he saves everything to, about a year old, that "over the weekend just stopped working. I saved some new files to it on Saturday night" — and then it did not work again. He can name the last moment the drive functioned, which fixes one end of the window in which whatever happened, happened.

The decode: what a dated last write establishes
Why the timestamp is worth more than it appears: a drive that accepted a write on Saturday evening was, at that moment, spinning, positioning its heads, reading its own configuration and committing data. Everything about it was working hours before it stopped, which excludes the slow deteriorations that announce themselves over weeks.
What that suggests about the fault: something that happens rather than something that develops. A board component failing, a supply stage giving way, an enclosure bridge dying — the abrupt category rather than the progressive one.
Why the distinction matters practically: abrupt electrical faults leave the mechanism and surfaces untouched, and the data is intact behind a component that has stopped working. Progressive surface faults are a different proposition, and the absence of any warning is evidence against the second.
The one thing worth being careful about, and it concerns those Saturday files specifically: they were the last things written. A file written shortly before a failure is the one most likely to be structurally incomplete — not because of the failure itself, but because recent writes are the ones whose supporting structures were most recently updated.
Why that is worth stating rather than assuming it will be noticed: people check the oldest and most precious material first and assume the recent additions are fine because they were just put there. The opposite is more often true.
What the drive's age contributes: a year is early-life territory, where manufacturing variation surfaces. Nothing he did caused this, and a drive that works for a year and then stops is behaving like a component that had a flaw rather than one that wore out.
Why the arrangement is the underlying problem rather than the drive: he saves everything to it. A single external drive holding the only copy is the arrangement this archive meets more than any other, and the drive being a year old made it feel safe.
What must not happen meanwhile: repeated connection to check. If the fault is electrical, attempts change nothing; if it is not, they cost something.
On the bench
The last successful write was treated as the reference point for volume state — a drive accepting a write hours before failing having been spinning, positioning, reading its configuration and committing data, which excludes progressive deterioration and indicates an abrupt fault. Most recent files were assessed for completion separately, files written shortly before a failure being those whose supporting structures were most recently updated and therefore least likely to be complete.
The outcome
The dated last write used as a reference, recent files assessed separately for completion, and the drive imaged under capped timeouts. 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: knowing exactly when it last worked is worth having. A drive accepting writes on Saturday evening was entirely functional hours before it stopped, which points at an abrupt fault rather than a developing one.
Noting when a drive last worked
Write down the last thing you did with it and when — that timestamp fixes one end of the window and it tells a technician more than most descriptions of symptoms. A drive that accepted a write hours before failing was spinning, positioning and committing data at that point, which argues against the slow deteriorations that announce themselves over weeks and points at something abrupt instead, usually electrical and usually leaving the surfaces untouched. One caution about the files you saved most recently: those are the likeliest to be structurally incomplete, since their supporting structures were the last to be updated. Stop reconnecting it meanwhile.
