Entendiendo el Archivo y el Sistema de Archivos
When a drive suddenly becomes inaccesible, corrupted, or unreadable, the root cause is often related to the file and file system rather than the data blocks. Don’t panic—the good news is that most situations are cuestiones lógicas, not physical, and can be understood and resolved with the right approach.
In practice, this article explains how files are organized on disk, how storage structures work together, the major storage formats in use, and practical methods to fix logical disk errors without risking further data loss.

What Is a File?
A archivo is a structured collection of data stored on a storage device. From the operating system’s perspective, a file is not just raw data—it includes metadatos such as:
- File name
- Size
- Creation and modification timestamps
- Access permissions
- Physical location on the disk
As a result, modern operating systems do not directly manage raw disk sectors. Instead, they rely on the file system to map files to physical storage locations efficiently and safely.
What Is a File System?
A logical storage framework controls how files are stored, organized, retrieved, and managed on a storage device. It defines:
- How data blocks are allocated
- How directories are structured
- How file metadata is recorded
- How free and used space is tracked
Common file systems such as NTFS, FAT32, exFAT, y EXT4 follow strict structural rules defined by operating system standards. For example, Microsoft’s NTFS relies on the Tabla maestra de archivos (MFT) to track every file and directory on the volume.
Without a functioning storage structure, data may still exist on the disk, but the operating system cannot interpret it.
File System vs. Filing System
Although often confused, these terms serve different purposes:
- File system: A technical, operating-system-level structure that manages digital data on storage media. In computing, this technical term is the correct and precise term.
- Filing system: A broader organizational method, which may include physical or digital classification systems used by humans or businesses.
Common Types of File Systems
Different operating systems and storage scenarios require different storage formats.
1. FAT32
- Widely compatible
- Limited file size (4 GB maximum)
- Minimal fault tolerance
2. exFAT
- Designed for flash storage
- Supports large files
- Common on SD cards and USB drives
3. NTFS
- Default for modern Windows systems
- Supports permissions, journaling, and encryption
- Highly resilient against corruption
4. EXT4
- Standard for Linux systems
- Efficient and stable
- Strong journaling support
Each file system balances performance, compatibility, and data integrity differently.
How Disk Structures Organize Data
Modern storage formats rely on internal structures to organize data. The most common include:
1. Hierarchical structure – Files arranged in directories and subdirectories
2. Flat structure – Minimal organization, used in simple systems
3. Indexed structure – Uses indexes to locate files quickly
4. Linked structure – Data blocks linked sequentially
5. Journaling structure – Tracks changes before committing them, reducing corruption risk
Modern file systems like NTFS and EXT4 primarily use hierarchical and journaling structures for reliability.
How to Check Disk Structure Integrity
If a drive behaves abnormally, checking the disk structure is the first safe step.
1. Abra Este PC
2. Right-click the drive
3. Seleccione Propiedades → Herramientas → Consulte
Alternatively, use Command Prompt:
chkdsk X: /f
(Replace X with the drive letter.)
This scans the logical structure for errors without modifying file content unless necessary.
How to Fix Logical Disk Errors Safely
Logical disk errors typically occur due to improper ejection, power loss, or interrupted write operations. Follow a structured approach:
Step 1: Stop Using the Affected Drive
Continued use may overwrite recoverable data.
Step 2: Identify the File System State
If the drive appears as RAW, the file structure metadata is damaged, but data often remains intact.
Step 3: Attempt Logical Repair
Use built-in tools like CHKDSK for minor issues.
Step 4: Recover Data Before Repair (Recommended)
Herramientas profesionales como Magic Data Recovery scan storage in read-only mode, locate disk structure records, and extract files safely—even when the underlying storage structure is corrupted or unrecognized.
This approach minimizes risk and preserves data integrity before any repair or reformatting.
Why Storage Structure Knowledge Matters for Recovery
Understanding how file systems work explains why data is often not permanently lost after supresión, formato, o corrupción. In many cases:
- File entries are removed
- Data blocks remain untouched
- Recovery is possible until overwritten
This is why professional recovery software focuses on interpreting disk structure records rather than guessing raw data.
Conclusión
Logical disk issues are common, manageable, and often reversible. With a clear understanding of file organization on disk and a careful recovery-first approach, you can restore access to your data safely and efficiently. Download Magic Data Recovery to scan and recover files from damaged or corrupted file systems in a secure, read-only environment.
