Data Recovery Case File · Apple Mac · Failing Internal Drive

The beachball, decoded: a 2015 iMac dying in slow motion — and the missing Safari its owner thought we'd never believe

The enquiry apologised for its own strangest symptom. The iMac took an age to switch on, beachballed at every click, restarted itself unbidden — and Safari had vanished from Applications, which the owner offered with a disarming "I know this will be hardly credible to you." It was entirely credible. Every symptom on her list, including that one, was the same patient: a hard drive failing by degrees underneath everything she could see.

The enquiry

“It has become virtually unresponsive when turned on — which takes an age — with a rainbow spinning wheel coming up each time I click, then not always opening, or restarting without my choosing. I also seem to have 'lost' Safari, as it doesn't appear in Apps either, which I know will be hardly credible to you. I have a lot of photos and other data I'd like to preserve, and of course I haven't backed up for a while. Could you give me a rough estimate by email — e.g. an hourly rate?”

One drive, wearing five disguises

iMacs of this vintage run on a conventional spinning hard drive, and when that drive begins failing, the whole computer becomes its symptom. The beachball is the drive: macOS waiting, click after click, on reads that stall against weakening sectors. The endless startup is the same wait at scale; the restarts are the system losing patience with a disk that stops answering. And the vanished Safari — far from incredible — was the most diagnostic clue of all: the filesystem's records were themselves being damaged as the drive decayed beneath them, and entries were falling out of the catalogue. Applications go missing this way; so, given time, do photo libraries. Which is why our first advice, delivered the same day, was the urgent kind: stop turning it on. Every beachballing session was hours of grinding reads on a drive with a shrinking number left in it.

The recovery

An iMac gives up its drive reluctantly — the display is sealed on with adhesive and must be lifted and later re-bonded properly, a genuine reason this is bench work and not a kitchen-table job. With the drive out, it went nowhere near another boot: imaged write-blocked on the Insight Forensic with error-tolerant discipline, the healthy majority read swiftly, the stalling regions — the beachball's home turf — worked last with bounded patience. From the image, the damaged catalogue was reconciled from its redundant structures in Data Extractor, orphaned entries (Safari had company) reunited with the tree, and the thing that actually mattered extracted whole: the photo library, years deep, verified album by album, alongside her documents and mail.

Outcome — and the answer to "what's your hourly rate?"

The photos and personal data recovered essentially complete, delivered on an external drive her next Mac could import in an afternoon. As for the pricing question in her enquiry: we don't do hourly, precisely because a customer shouldn't bear the meter-risk of how stubborn her own drive turns out to be — assessment free, then one fixed written figure for the fault, by email as requested, decision entirely hers. A machine can be worth fixing or not; that arithmetic changes house to house. The photos' arithmetic never does.
