External Drive Not Showing Up? How To Avoid Making Recovery Harder
A drive that suddenly disappears is not a good place for random trial-and-error. These first steps protect the best recovery options.

Carshalton is one of the leafier corners of our patch — the ponds and conservation area around the Village, the quieter avenues of Carshalton Beeches, the more mixed streets toward the Wrythe — and a good share of our SM5 calls are settled households with a machine that has been in the family for years and quietly slowed. We come to your door for data recovery rather than have you drive a fragile machine into Sutton, drives that won't mount, accidentally deleted files, failed SSDs and clicking hard drives included.
There is no callout charge either way, a fixed quote before we start, and no fix, no fee on every job.
Data recovery starts with working out which kind of problem you actually have, because the two kinds are not remotely alike. A logical failure — deleted files, a formatted card, a corrupted partition, a drive that mounts but shows nothing — leaves the hardware intact and the data usually still physically present. A physical failure — clicking, grinding, a drive that never spins up, an SSD the Mac no longer sees at all — is a hardware problem, and no amount of software will fix it. Diagnosis is free, and we tell you which one you are dealing with before you commit to anything.
Logical recoveries are often done in front of you. We work from a copy wherever we can rather than the original drive, so nothing we do makes the situation worse, and you can see the files reappearing as they are found. Where the drive is healthy enough, this is frequently finished in a single visit and your files come back onto a drive or a machine you already have.
This is our dedicated data recovery page for Carshalton. For the full picture of everything we repair here, see our Carshalton repair page, or our London-wide Data Recovery service.
Across Carshalton, the data recovery calls we get most often involve drives that won't mount, accidentally deleted files, failed SSDs and clicking hard drives — though we are called out for plenty more besides.
Because so many Carshalton machines are long-owned and well cared for, the everyday job here is revival rather than resurrection: SSD and memory upgrades on iMacs and MacBooks that have got sluggish, clean reinstalls to clear years of software clutter, and battery replacements on machines that no longer last a working day. It's the cheapest thing you can do to a slow computer, and we'd rather fit one than sell you a repair you don't need. Cracked screens and worn keyboards on family and student MacBooks are steady too, and we carry the common Air and Pro panels so most of those are done in front of you. The home-office side around the Beeches brings more backup and data-recovery work than average — people running everything off a single machine — and checking that your backup actually runs is free advice we give on every visit. Liquid spills at a kitchen-table desk come up now and then, and there the speed of the call decides how much survives.
Agreed upfront before we touch your device. No surprises.
Carshalton is a short run from our New Malden base, so same-day is usually straightforward if you call before 2pm. Parking is generally easy on the residential avenues around the Beeches and tighter near the ponds and the Village conservation area, so for those we'll check access with you when you book rather than circling. There's no callout charge anywhere in the borough, evenings and weekends cost the same as any weekday slot, and every repair carries our 90-day parts-and-labour warranty — with nothing to pay at all if we can't fix the fault.
No shop drop-off. We travel to your home or office in Carshalton at no extra charge.
Most repairs done on-site within the hour. Book before 2pm and we aim to visit the same day.
Quality replacement parts, backed by a 90-day parts and labour warranty.
If we cannot fix it, you pay absolutely nothing — no diagnostic or callout fee.
