A Bent Read/Write Head, They Said.
The verdict travelled ahead of the parcel. His computer shop had heard the ticking, kept the lid on, and said it straight — the read/write head's bent
and that's a clean-room job, not ours
. The Seagate was second-hand, part of a job lot from a Yeovil builder packing it in, and it went over mid-copy, dragged from the cabin bench by its own lead. On it: every before-and-after photo since I went out on my own

In plain English.
Credit the shop twice: once for the diagnosis, once for knowing where their job ended. Nobody straightens a bent head — the gap it flies above the platter is set at the factory to tolerances no bench in the land can put back, so the cure is a matched donor stack, full stop. The honest unknown after any fall is what lies beneath. A drive knocked over while working may have let a head meet the surface, and marks of that sort are worked around, never read through. Anyone quoting you a total before opening it is selling confidence, not knowledge.

|---|---|---|
| DeepSpar Disk Imager 4 | Graded each surface once the donor stack was in and reading | Images by head map — timeouts, resets and power-cycling managed per head |
| PC-3000 Data Extractor | Ordered the passes so the scuffed band waited until everything else was safe | The PC-3000's imager, taking its orders from the firmware side |

On the bench.
Open it, and let the platters set the terms
Under magnification the shop's call held up: the stack sat visibly out of true, useless as an instrument. What counted more lay underneath. The touchdown had scuffed a narrow band on one surface — real harm, yet shallow, nothing like the circular scoring that closes a case — while the firmware's log filled in the drive's past: a hard-worked unit long before it became his.
A matched donor for a slim mechanism
Seagate builds these portables slim, and slim mechanisms are fussy about transplants: donor and patient had to match on family and firmware generation, the label's model number only the start. The stack from our donor stock went in under clean air, the drive spun up steady, and a head-by-head grading set the plan before bulk copying began.
Sound ground first; the scuffed band at the end
While the drive was freshest, the untouched surfaces were copied to the last sector. The marked band came last and got economy rather than heroics — short visits, few retries, rests in between — and gave up a worthwhile share of itself before the point of diminishing returns arrived.
How it ended.
He got back nearly the whole record — years of before-and-after photographs, checked and set out job by job — along with a straight account of the gap: one folder of site photographs sat under the scuffed band and stayed there. For a used drive dropped live, holding the only copy in existence, the ledger closed well in his favour.
