Fájlrendszerkorrupció

Fájlrendszerkorrupció refers to the state of a file system where errors have occurred, leading to data inconsistencies or inaccessibility. This corruption can manifest in various ways, such as corrupted files, unreadable directories, or the entire file system becoming inaccessible. It can prevent users from opening files, saving new data, or even booting the operating system.

The causes of file system corruption are diverse. Hardware failures are a common culprit, including faulty hard drives, memory errors, or power surges that interrupt write operations. Software bugs within the operating system or file system drivers can also introduce errors. Unexpected system shutdowns, such as power outages or hard resets, can leave the file system in an inconsistent state if data was being written at the time. Malware infections, particularly those designed to disrupt system operations, can deliberately corrupt file system structures.

Detecting file system corruption often involves error messages displayed by the operating system or disk utility programs. Tools like CHKDSK on Windows or fsck on Linux are designed to scan for and attempt to repair file system errors.

Preventive measures include maintaining stable power supply with a UPS, regularly backing up important data, and ensuring proper system shutdowns. Keeping operating systems and drivers updated can also mitigate risks from software-related corruption. When corruption occurs, data recovery specialists or specialized software may be necessary to salvage lost information, though complete recovery is not always guaranteed.
