Nearly every hard drive fault is mechanical, electronic, firmware or logical — and the category decides everything: the route, the price, and whether the drive is deteriorating while you read this. Only one of the four gets worse with power, and that is the one that makes a noise.

Clicking, ticking, grinding or beeping all mean the mechanism, and all get worse with every minute of power. That single decision affects the outcome more than anything else you can do — more than cables, software, or which lab you choose.
Nearly every hard drive fault falls into one of these, and the category determines the route, the price and the urgency.
Drives arrive here from machines built last year and from machines built before some of the software running today.
SATA, SAS, IDE and PATA, SCSI, and 2.5-inch laptop drives through to 3.5-inch desktop and enterprise units. Every major manufacturer — Seagate, Western Digital, Toshiba, Hitachi and HGST, Samsung, Maxtor, Fujitsu, and the legacy names that predate them.
Elderly drives are a genuine speciality rather than an afterthought. A twenty-year-old Maxtor or an IDE drive from a machine long since scrapped presents its own problem — donors are scarce — but the recovery itself is well understood. If you have a drive you assumed was too old to bother with, it is worth asking. See also hard drive advantages and disadvantages.
The whole method rests on one principle: a failing drive may only have a single good read left, so it is spent on a copy.
The fault is classified before anything else, because mechanical, electronic, firmware and logical faults need entirely different handling.
Donor heads, board repair with the original ROM adaptives migrated, or service-area work — enough to make the drive readable, not to make it usable again.
Cloned on hardware built for failing media, with per-head timeouts and unreadable sectors logged rather than allowed to stall the process.
File system repair, extraction and carving all happen against the clone. The original is never written to.
Recovered data is checked by opening it in its applications, and anything unreadable is reported by name rather than returned as a file that opens to nothing.
One price for a single drive, whatever the fault turns out to be.
A single hard drive — internal, external or from a laptop — is from £300 +VAT, confirmed in a written quote after the free 48-hour diagnostic. Where the drive is part of a RAID, NAS or server, that work starts from £500 +VAT. Most jobs are no fix, no fee; clean-air and donor-part work carries a 50% deposit with the balance payable only on success.
Send the bare drive rather than the whole machine where you can — cheaper to post and quicker to start. External units are the exception and should come complete with the enclosure.

Send the drive in for its free diagnostic with a brief fault description; an engineer evaluates it and confirms the exact quote in writing before any work starts.
Getting your data back begins with getting the device to us. Pack it up safely, pop your contact details inside, and send it over — once we’ve run the free diagnostic, we’ll confirm your exact price in writing before any work starts.
Posting it? A tracked, insured service is what we’d recommend. Rather drop it in? You’re welcome Monday to Friday, 9am to 5:30pm — just package the device up as above first.
Need a scoped quote first? Describe the drive and fault on the form and an engineer will assess it and reply with a tailored quote.
We’ll be in touch shortly. If it’s urgent, call 01865 593000.
Because we work at platform and firmware level rather than through consumer brand utilities, the label on the enclosure rarely sets the method: Western Digital (Blue, Black, Red, Gold, Ultrastar), Seagate (Barracuda, IronWolf, Exos and Rescue-bundled drives), Toshiba, Hitachi/HGST, Samsung and legacy Maxtor all get the same discipline — stabilise the mechanics, carry the adaptives across, rebuild the service area, image read-only. Firmware families vary; the imaging-first approach doesn’t.
The technical questions we get most about failed hard drives.
Usually, but power it off now. Clicking means the heads cannot find their servo data, and every rotation risks scoring the surface holding your files. Recovery means fitting a matched donor head-stack under filtered clean air, then imaging in short passes.
Typically firmware rather than mechanics. Drives load their operating code from a reserved service area, and if a module is unreadable the drive cannot describe itself — so it reports no capacity or a blank model while sounding perfectly healthy. The data is generally untouched.
Yes, and often. Elderly drives are a speciality rather than a problem — the recovery is well understood, though donor parts can be scarce for unusual models, which sometimes affects timescales rather than feasibility.
The drive on its own where possible — cheaper to post, less to go astray, and faster to begin work on. Any local computer shop will remove it in minutes. External units should be sent complete with their enclosure.
Not repairing, no. A drive that has started retiring sectors will keep doing so. Recover what matters and replace the drive — repair tools aim at a consistent file system rather than preserving your files.
