A Fall Mid-Copy That Took the Plug With It.
The copy was still running — two years of interviews coming off an ageing laptop — when a Beaconsfield journalist caught the cable on a chair arm. The Canvio came off the desk in the middle of a copy
and the connector was pulled clean out as it fell
. It now grinds for a second or two, then stops
, and nothing will pick it up at all
. Her instinct about the timing was right.

In everyday terms.
The same fall can cost nothing or cost a great deal, and the difference is whether the drive was busy. Powered down, the heads rest on their ramp with the platters left alone, and a drop from desk height is very often survived without a mark. Mid-write there is no ramp involved: the heads are out over the surface, the arm is travelling, and the landing is over long before any retract command could run. This one fell at the wrong instant.
What the bench used here.
How a job is handled →| Tool | Why we used it | What it brings |
|---|---|---|
| DeepSpar Disk Imager 4 | Ranked the heads first, and the ranking set the order of the passes | Head map first, then head-by-head reads, holding resets, timeouts and the power line steady |
| PC-3000 Data Extractor | Ran the imaging, resolving each lock-up with a measured power cycle | The PC-3000's imaging module, working under firmware-level control |
| R-Studio Technician | Rebuilt the file system from the image, the interrupted folder included | Its file-system coverage is wide and its array rebuilds hold up |
The lab work.
Establish what the impact left before anything moves
Under laminar flow the stack told the usual story of an impact taken in flight: the harm is uneven. Two sliders were visibly disturbed, the rest almost unmarked. A thin band of contact scuffing followed the line along which the arm had been pressed against the platter — genuine harm, shallow though it was, and nothing like the ring-shaped gouging that ends a case.
Fresh heads, a surface survey, then an ordered read
A donor stack for the correct model was fitted, and the surfaces were then mapped. The order of work chose itself: healthy ground came off quickly while the mechanism was at its best, and the scuffed band was left deliberately until last, to be worked slowly with resets ready.
Handle the scuffed band as the loss it already is
The strip lying beneath the heads at the moment of landing was left until the end and crossed at walking pace, retry limits set generously. Most of it came back. No operating system was ever allowed near the drive; the imager asked for each sector once, gently, and never went back for a second try.
How the job closed.
The archive came back very nearly complete. What it cost was a small number of interviews that sat inside the scuffed band, each named in the report. The folder the laptop had been part-way through writing arrived intact in the end, lifted from the image with the drive powered down.

Does any of that match your case?
Nothing needs deciding until the diagnosis is back: switch the device off, send it in, and let the findings settle it.
