Ten Years of Files, and No Parts Left.
A grey screen, then a blinking folder with a question mark on it, and the MacBook Pro was finished. The shop told her straight: we swap parts here, we do not read them
. Nothing has been offered for a 2011 machine in years. It had run a letting agency from a spare room in Chepstow for a decade — properties on both sides of the Wye — and the disk held a photograph of every place we have ever managed
along with all the tenancy agreements, right back to the start
. There was no copy anywhere.

Why that happens.
Age worked both ways on this job. On one side, no supplier has carried parts for a 2011 drive in a very long time, and no amount of asking changes it. On the other, magnetism does not expire the way a spares catalogue does. Whatever was written to those platters is still written there, and a mechanism coaxed into one carefully planned run will usually give it up. That is why the shop was right rather than unhelpful. A repair counter is there to identify a fault and sell the part that fixes it, and she got both, honestly. Pulling readable files off a dead mechanism is a different trade altogether — donor stock, filtered air, imaging hardware no shop floor has space for. An ageing disk tends to allow one go and punish the second, so everything rides on not wasting the first.
What we used on this one.
Every step, in order →| The tools | What it did here | Why it helps |
|---|---|---|
| DeepSpar Disk Imager 4 | Ranked every head with the donor stack fitted, and took the strong surfaces first | Maps the heads first, works surface by surface, and keeps resets, timeouts and power in hand |
| PC-3000 Data Extractor | Held the read rate to what a drive of that vintage could tolerate | Imaging driven from inside the drive's own firmware, by the PC-3000 |
| UFS Explorer Professional Recovery | Rebuilt the HFS+ volume from the image, with folders and dates intact | Reads the volume formats that defeat most software: APFS, ReFS, XFS, ZFS, Btrfs |
How it went.
Take stock before anything is disturbed
It took minutes to establish that the heads were gone, and the survey ran to the end regardless — spindle bearing, surface condition, and ten years of defect history from a disk that had lived in a warm room beneath a printer. Every reading said the same thing: go gently. No powering it up to see. Nothing attempted on instinct. If there was a single run left in that mechanism, it would be worked out on paper first.
Finding a donor that matched on more than a label
You cannot order parts for a drive of this age; you hunt for them. This one came off our own shelves, and it had to match the patient in three respects — family, firmware generation and preamp — the number on the label marking the start of that check, not the end of it. Fitted under laminar flow, the disk woke up, though unevenly: one head trailed the others from the very first pass.
Slow passes, then everything else on the image
Imaging went in passes at a deliberately gentle rate. The weak head was left until last and rested between its turns; a faint band of contact damage on that platter explained why it trailed. From then on every operation ran against the image and none against the drive. The HFS+ volume returned as a proper structure — one folder per property, dates as recorded — rather than a pile of numbered files.
Signing it off.
The property photographs and ten years of tenancy paperwork went back verified, in order, and opening as they should — bar a handful of pictures that were sitting on the weakest surface. Rather than quietly dropping those, we listed them by filename, and most are exteriors she can go out and shoot again. Everything went home on a fresh disk, and a second copy went with it. The MacBook now sits in a drawer, honourably retired.
