Hard drive problems.

Clicking, vanishing, dying or dead — the most common drive symptoms, and what to do about each.

Mac Recovery Software: What Works on APFS

APFS changed what recovery tools can do. Snapshots, containers and encryption — what to check before buying anything, and when software cannot help.

BitLocker Recovery Key: Six Places It Is Stored

Work machine or personal? That question resolves most BitLocker lockouts. Six places the 48-digit key lives, and what happens if it is truly gone.

Buffalo Data Recovery: LinkStation, TeraStation, Drives

Buffalo NAS units run standard Linux storage with the OS on the member disks. What that means when one fails, and why the box is often the…

04

Can Data Be Recovered From a Failed SSD? Usually

SSDs fail without warning because SMART reports wear, not controller health. What actually fails, and why a dead SSD beats a working one.

05

Types of Hard Drive Failure: Which One Do You Have?

Mechanical, electronic, firmware or logical — four failure classes, how to tell them apart yourself, and which two get worse while you decide.

06

Corrupted SD Card? Take It Out and Stop Shooting

A corrupted card is not deteriorating — only writing destroys it. What corruption usually means, why exFAT is fragile, and three free checks first.

07

Data Recovery Cost UK: What Actually Sets the Price

Four things determine cost and data volume is not one of them. Published UK figures, four questions to ask any firm, and no-fix-no-fee…

08

Recovery Software or a Lab? One Question Decides

Software reads the drive — brilliant on healthy hardware, harmful on a failing one. Four questions, three cases where software wins, and…

09

Disk Drill and Tools Like It: What to Check First

Rather than a star rating, the four things that decide whether any recovery tool helps your case — and the situations where none of them do.

10

Does Apple Do Data Recovery? No

The Genius Bar diagnoses and replaces hardware, and the failed drive leaves with the old parts. Recover first, repair second — plus three…

11

Does a Factory Reset Delete Everything? It Depends

Reset options differ enormously in what they actually do — and on an SSD, one of them is irreversible within minutes.

12

Free Data Recovery Software: What the Tiers Cover

Free tools genuinely work on the right cases. What the limits usually are, what to check before installing, and the cases where none of them help.

13

External Hard Drive Not Showing Up? Start Here

Four free checks before you assume the drive is dead, what each Windows symptom means, and why you should never shuck a WD external.

14

Hitachi & HGST Recovery: From Deskstar to Helium

Hitachi inherited IBM’s drive business and became HGST before Western Digital acquired it. What that lineage means when one of these arrives.

15

How Data Recovery Works: Read Once, Work on the Copy

A failing device may have few good reads left. The four stages, the four layers that can break, and four honest limits on what is possible.

16

Forensic Data Recovery: Proving Nothing Changed

Recovery returns files. Forensic work proves nothing changed. Write blockers, SHA-256 hashing and chain of custody explained.

17

How to Check Hard Drive Health: The Two Numbers

Ignore the Good/Caution verdict. Read reallocated and pending sectors instead — plus what SMART cannot tell you, and the symptoms it misses.

18

How to Check SSD Health: What the Numbers Miss

SSD SMART reports wear accurately and controller health barely at all. Which attributes matter, and what they cannot tell you.

19

Failed RAID: What to Do in the First Hour

A failed array is not deteriorating — interventions are what cause damage. Five things not to do, five details to record, and how layout is derived.

20

How to Recover Deleted Files: What Actually Works

Deleting removes the index entry, not the data — on a hard drive. On an SSD, TRIM erases it in minutes. Four free checks before you pay anyone.

21

External Hard Drive Recovery: What You Can Safely Try

Once the drive is detected, some recovery is genuinely a DIY job. Where that line sits, what is safe to attempt, and the WD trap to avoid.

22

Iomega Data Recovery: Zip Disks and Legacy Media

Iomega media is now decades old and frequently the only copy of something. What survives, what the click of death was, and what modern…

23

LaCie Recovery: Enclosures, RAID and the OS Problem

LaCie units range from single portable drives to multi-bay RAID enclosures — and on the RAID models, the operating system lives on the disks.

24

Maxtor Data Recovery: Legacy Drives, Live Data

Maxtor became part of Seagate in 2006, so these drives are all at least that old. What still works, and why the initialise prompt matters most here.

25

NAS Not Accessible? Ping It Before You Panic

Four things “cannot reach my files” can mean, and only one is a data problem. Two ten-second checks that locate the fault, and three actions to avoid.

26

The machine started fine and found nothing to boot from. Four causes, three free checks, and why your files are almost certainly untouched.

27

RAID 10 survives multiple failures — but only the right ones. How it is built, which two-disk losses are survivable, and why it fails silently.

28

RAID Won’t Rebuild: Stop Before You Try Again

A rebuild that stalls or fails is telling you something specific. What each failure mode means, and why retrying is the costly response.

29

Dead Hard Drive Recovery: Define “Dead” First

Four very different states get called dead, and they have completely different prospects. How to tell which you have before spending anything.

30
