Logical Errors in File Systems: NTFS, EXT4, XFS, and ZFS
Failures in hard drives, SSDs, and corporate storage systems are not limited to physical defects. In many cases, loss of data access occurs due to logical errors in the file system — events that compromise the readability, structure, or integrity of stored data, even when the hardware is functioning perfectly. These errors can occur after sudden shutdowns, metadata corruption, failed
Human Error in RAID: When the Failure Is Not Technical but Operational
Failures in RAID systems are commonly associated with disk loss, data corruption, or cyberattacks. However, a frequently overlooked and statistically significant factor is human error. Swapping disks in the wrong order, initiating a rebuild without prior diagnostics, accidentally formatting the volume, or even reinstalling the system over the original array are events more common than one might think — even
Corrupted RAID: signs of failure and what to do before losing your data
Environments with RAID systems are designed to ensure high availability and fault tolerance. However, these systems are far from infallible. RAID volume corruption can occur silently and progressively, putting critical data at risk even when no physical disk has failed. Many IT managers only realize the problem when it’s already too late: inaccessible files, sudden slowdowns, read errors, and, in
Recovering data from a RAID encrypted by ransomware: is it possible?
RAID solutions are widely adopted by companies to ensure availability, redundancy, and performance in data storage. However, even robust configurations such as RAID 5 or RAID 10 are not immune to cyberattacks.In an increasingly common scenario, ransomware groups infiltrate systems, encrypt the data on RAID volumes, and demand millions in ransom to restore access. This raises a critical question for
RAID 5 or RAID 10? Which one offers better protection against data loss?
In corporate environments where operational continuity depends on fast and secure access to data, choosing the correct RAID level can make the difference between stability and total data loss. Among the most common options, RAID 5 and RAID 10 stand out for offering different combinations of performance and protection. However, when it comes to real fault tolerance and post-incident recovery
BCDR and cyber resilience: How to ensure continuity even after ransomware attacks
Ransomware is no longer an isolated incident: it is an operational risk that disrupts sales, customer service, supply chain, and decision-making. In hybrid environments — with critical applications distributed across data center, cloud, and SaaS — the question is no longer “if” it will happen but “when” and “with what impact”. This is the point where cyber resilience stops being
