Powered and Spinning, Yet Nowhere on the Desktop.
A Theale photographer had imported Saturday's job and copied it across. By Tuesday the drive had stopped cooperating: the icon turns grey and no volume ever appears
. The assistant's MacBook said what the studio iMac said. Throughout it, it has power, it turns, the light behaves exactly as normal
. The orange bumper held a year's worth of client RAW, and with it the Lightroom catalogue carrying every crop, correction and rating those files had been given. Lose the database and you are left with unedited frames. That Rugged Mini had lived in a working bag through two seasons, and plenty of jobs had ended with a cable tugged out of it late in the day.

What actually caused it.
Spin and a lit LED clear one obstacle out of four. Above the motor sit the USB bridge, the firmware, and the volume structures themselves — and macOS will not put an icon on the desktop until it has worked through all of them. Break any single layer and a mechanically sound disk is as good as missing. The catalogue is what made this more than a disk job. Adjustments in Lightroom are never written into the pictures; they sit in a database alongside. Hand back only the RAW files and a year of decisions has quietly gone.
What this one needed on the bench.
How every job runs →| Bench tools | Its part in this job | Why it is here |
|---|---|---|
| ACE Lab PC-3000 Express | Pushed the motor, the heads and the firmware; every one of them behaved | Gets into the manufacturer's own service mode, which plain ATA never reaches |
| PC-3000 Data Extractor | Took the whole disk, with the small structural areas queued ahead of the terabytes | Copies at firmware level, through the drive's own controller rather than around it |
| UFS Explorer Professional Recovery | Rebuilt the damaged Mac volume, then realigned the catalogue's folder tree | Opens volumes other tools refuse: APFS, ReFS, XFS, ZFS and Btrfs |
What the bench did.
Rule out the hardware first
Nothing was physically wrong with this disk, and four checks said so: no damage worth recording, firmware answering every question put to it, a defect list with nothing unusual on it, and clean test reads off each head in turn. That puts the fault higher up — in the bookkeeping a Mac works through before it will show you a volume.
The catalogue comes off before the pictures
Nothing was copied until the order had been decided. First out were the volume descriptors and the catalogue database; the terabytes of RAW came afterwards. Those few gigabytes at the front are the difference between an archive that opens and works, and several thousand unsorted images.
Then run it as she would
A library can shed every adjustment it holds and still hand back the right number of files, so a count proves nothing here. The recovered catalogue went into Lightroom instead, the collections came up as they should, and edited frames were compared against the originals underneath them. Nothing goes home from this bench on the strength of a listing.
What went back.
Both went home together — database and images, edits still bound to the pictures — after being opened and tested in her own copy of Lightroom rather than in ours. There was one loss, and the report puts it in the first line instead of burying it further down: Saturday's import had been only half written when the volume structures failed, and no platter hands back data that never reached it.

Post it in as it is, switched off. Looking costs nothing, and you get one fixed figure in writing before any chargeable work begins — £250 + VAT for a card or stick, £300 + VAT for a single drive, from £500 + VAT for RAID and NAS. On most jobs, nothing is charged unless your data comes back.
