Hard Drive and SSD Overheating: Temperature Limits, Throttling and Heat Waves

A heat wave, a poorly ventilated equipment room, a NAS tucked into a closed cabinet: heat shows up in the life of a storage device more often than people expect. Mechanical hard drives and SSDs do not react to it...

SSD data recovery with TRIM enabled: why deleted files are often gone for good

On a traditional hard drive, a deleted file often remains readable for a long time: only its entry in the file system index disappears, and the data stays in place until something overwrites it. On a modern SSD, that assumption...

exFAT vs NTFS: which file system for which storage device

When you format an external drive, a USB stick or a memory card, the system offers a list of formats: NTFS, exFAT, FAT32, sometimes APFS. The choice looks harmless, yet it decides which devices the storage will work with, how...

Cloning a Hard Drive Before Data Recovery: Method and Limits

When a hard drive starts to struggle, the instinct is nearly always the same: run another scan, copy the important files in a hurry, or install recovery software. Each of those actions puts load on a device nobody knows how...

Why RAID Is Not a Backup

"Our server runs RAID, so our data is safe." It is a common sentence, and it rests on a mix-up: RAID and backup answer two different questions. RAID answers "will my service keep running if a disk fails?". A backup...

Why an SSD Can Lose Data When Left Unpowered

An SSD stored in a drawer, an external drive forgotten on a shelf, an old system disk kept aside just in case: we assume they are safe because nothing spins or heats up anymore. That assumption is only partly true...

Microsoft Storage Spaces Direct (S2D): what to know before a failure

More and more businesses are moving away from traditional RAID arrays or dedicated SANs in favour of Storage Spaces Direct (S2D), the software-defined storage technology built into Windows Server since the 2016 release. The appeal is clear: pool the local...

Data Recovery on Windows 11: What Has Really Changed

Windows 11 has quietly rewritten the rules of data recovery. Encryption enabled by default, the shift to NVMe SSDs everywhere, and a new file system slowly making its way in: each change looks minor on its own, but together they narrow...

Synology/QNAP NAS Failure: The Mistakes That Make Data Loss Worse

A Synology or QNAP NAS reporting a failed drive isn't a data loss event yet. What usually decides the outcome isn't the failure itself, but what happens in the hours that follow. A reset that wipes the RAID metadata, a...

CMR vs SMR: What’s the Difference for Your Hard Drive and RAID Array

Two hard drives with the same capacity, from the same manufacturer, sometimes sold at the same price, can still behave very differently once installed in a NAS or a RAID server. The reason comes down to a technical difference you...

RAID Rebuild Without Data Loss: Steps & Mistakes

A drive fails in your RAID 5 or RAID 6 array. The controller drops into degraded mode and offers to start the rebuild, recalculating the missing data from parity. That moment, before you even confirm the rebuild, is where the fate of...

RAID 5 Fire & Water Damage: Data Recovery Guide

Ransomware Decryptor Not Working? What to Do

You paid the ransom, received the key, or downloaded a free decryption tool published by a security researcher, and your files are still unusable. This scenario is more common than most people assume. On complex formats like SQL databases or...

Power Outages: The Hidden Data Loss Risk for Servers/NAS

A power outage rarely lasts more than a few seconds. That is still enough to render a RAID volume unreadable or corrupt an entire file system on a server or NAS. Contrary to popular belief, the risk does not come...

MSSQL Database Lost in a Corrupted VM: Recovery Guide

The application server stops responding, the hypervisor flags the virtual machine as failed, and it simply won't restart. Look closer, and the SQL Server database behind your ERP, CRM, or line-of-business app has vanished outright. This scenario, increasingly common in...
