Straight-talking guides on failing drives, lost files and what to do before you make things worse — written by the engineers who recover this stuff every day, in-house.
The single best thing you can do for a clicking or failing drive is stop using it and get in touch. Powering on a failing drive is what usually turns recoverable into lost.
Clicking, vanishing, dying or dead — the most common drive symptoms, and what to do about each.
Mac recovery software has to handle APFS containers, snapshots and SIP — and on Apple Silicon it often cannot reach the disk at all. What to try, in order.
What BitLocker recovery means, why Windows asks for a key, how long it takes, and every place the 48-digit key is stored.
Buffalo LinkStation and TeraStation units run standard Linux RAID under a closed interface. Why EM mode isn’t fatal and what a firmware restore costs.
SSD recovery splits in two — a failed drive holding your data is usually recoverable, deleted files on a working one usually aren’t. Why, and what decides it.
Hard drives fail in four distinct ways — mechanical, electronic, firmware and logical. What each looks like, what it sounds like, and which are recoverable.
A corrupt SD card is usually a damaged file system or a failing controller, not lost photos. What to try safely, and the one prompt you must never accept.
UK data recovery prices vary from £250 to several thousand. What actually drives the difference, which pricing models to be wary of, and typical figures.
Whether software will work is decided before you download anything. Four questions that tell you which route you are on.
An honest look at Disk Drill from a recovery lab — where it genuinely works, where the free tier stops, and the situations no software should be pointed at.
Apple replaces hardware; it doesn’t recover data, and some of what it does will erase yours. What the Genius Bar offers and where a lab takes over.
On encrypted devices a reset destroys the key and the data is gone. On others it just marks space free. Which is which, and what it means for recovery.
Most free recovery software scans for nothing and charges to save. Which tools are genuinely free, what the limits are, and the risk nobody mentions.
An external drive that won’t appear is usually a cable, bridge board or partition problem, not a dead disk. The checks in order, and when to stop.
Hitachi and HGST drives carry IBM’s Deskstar lineage and now sit under WD. What that means for donor parts, helium Ultrastars and stuck-head failures.
Data recovery is imaging first, everything else second. What happens to a drive in a lab, why the original is never written to, and what decides the outcome.
Forensic recovery has to prove nothing changed. Write blockers, hashing, chain of custody and the ACPO principles, explained plainly.
How to tell whether a hard drive is failing — the five SMART attributes that actually predict failure, what the noises mean, and when to stop testing.
How to read an SSD’s real health — which SMART attributes matter, what percentage used and wear levelling actually mean, and the warnings worth acting on.
What to do when a RAID fails — the rules for every level, what changes between 0, 1, 5, 6 and 10, and the one action that ends it.
Deleted files usually still exist until something overwrites them. The order to try things in, why SSDs differ, and when software stops helping.
If your external drive still connects but the data has gone, some steps are safe and some are not. What to attempt yourself, and the point to stop.
Iomega externals, eGo, StorCenter and the Zip click of death — what each failure means and when the drive should be read professionally.
LaCie makes enclosures, not drives — which changes how these fail. Rugged, d2, 2big and Thunderbolt, and why the disk is usually fine.
Maxtor DiamondMax, OneTouch and Basics drives are now 15–25 years old. Why they fail when powered up after storage, and how the data is read off safely.
A NAS is a computer, not a disk, so “not accessible” means four different things. How to tell network from share from volume from array.
“No bootable device” means the firmware can’t find a bootloader — which has four causes, from a changed boot order to a dead drive. How to tell them apart.
RAID 10 mirrors then stripes, giving speed and redundancy without parity. How many disks it survives, how it compares to RAID 5, and what recovery involves.
Why RAID rebuilds fail, what “data corrupted after rebuild” actually means, and whether an array can still be recovered once a rebuild has already been run.
“Dead” covers four very different faults, and only one is genuinely bad news. How to tell which you have before spending anything on it.
Deleted photos usually sit on the card until something overwrites them. Where they hide, why RAW carves well, and what to do before shooting again.
Samsung SSD recovery across the range — 970 and 980 NVMe, SATA EVO and PRO, and T5/T7 portables where encryption is on by default and changes everything.
SanDisk media fails in predictable ways — monolithic cards, Extreme portable SSDs and counterfeit stock. What each needs and what to avoid doing first.
Seagate recovery across the range — Barracuda, IronWolf, Exos and Expansion. Firmware-module faults, SMR complications and what each failure sounds like.
Drives usually warn you before they go. The signs that mean act today, the ones that mean act now, and the ones that are probably something else entirely.
Toshiba supplies the drive in many laptops carrying another badge. Why laptop repair and data recovery are different jobs, and what Canvio units need.
Repairing a USB stick and recovering its data are opposite operations — one writes, one doesn’t. Snapped connectors, format prompts and monolithic chips.
Why a WD My Passport disk is unreadable outside its own enclosure, what the bridge board actually does, and how WD internal and external drives are recovered.
A Data Recovery Agent is a Windows account that can decrypt EFS files when the original user cannot. What it is, why it exists, and what happens without one.
Crypto recovery means finding the seed phrase or wallet file, not breaking the device. What’s genuinely recoverable from failed media, and what isn’t.
A clicking drive is the heads failing to find their bearings, and every retry costs data. What the different rhythms mean and why it can’t be fixed at a desk.
A CRC error means the drive read data that failed its own checksum. What causes it, why chkdsk is usually the wrong response, and how the data is read back.
This NTFS error means the index entry for a file or folder can’t be read, usually from bad sectors or a bad ejection. Why chkdsk is the risk, not the fix.
Access denied, parameter incorrect, not formatted — one Windows error with different endings, each pointing somewhere different. What not to click.
This chkdsk message means part of the NTFS file table can’t be read. A few is repairable; hundreds means a failing drive and chkdsk is the wrong response.
Hard drives still win on cost per terabyte and cold storage; SSDs win on everything involving speed. Which to use for what, and how each fails.
RAID 1 data recovery explained — why mirrors fail together, how two degraded copies are merged into one good image, and why rebuilding is the risk.
RAID 0 data recovery — why one failed disk takes the whole stripe offline, how the array is reassembled from read-only images, and what comes back.
What to do when a backup fails or disaster takes your data out — emergency recovery for servers, RAID and NAS across Oxfordshire.
QNAP NAS data recovery — volumes that won’t mount, failed RAID members, thin pools and lost snapshots, rebuilt outside the unit.
Samsung 860 EVO signature failure, controller and firmware corruption explained — what each fault means and how the data is read back off the V-NAND.
When you can safely DIY, and how to get deleted files back without making things worse.
Higher-stakes recoveries — failed arrays and solid-state drives — explained simply.
Seagate, WD, Toshiba, Samsung and SanDisk — the makes we see most, and what to do when yours fails.
