Data Recovery Concept
Data Recovery Concept Overview
To understand underlying mechanisms of data storage, organization and recovery, the following topics can give essential concepts:
- Understanding Hardware and Disk Organization
- Basic information about Hard Disk Drives (HDD) and low-level disk organization.
- Understanding File System (FAT)
- The FAT file system is a simple file system originally designed for small disks and simple folder structures. The FAT file system is named for its method of organization, the File Allocation Table, which resides at the beginning of the volume. To protect the volume, two copies of the table are kept, in case one becomes damaged. In addition, the file allocation tables and the root folder must be stored in a fixed location so that the files needed to start the system can be correctly located.
- Understanding File System (NTFS)
- The Windows NT file system (NTFS) provides a combination of performance, reliability, and compatibility not found in the FAT file system. It is designed to quickly perform standard file operations such as read, write, and search — and even advanced operations such as file-system recovery — on very large hard disks.
- Understanding Recovery Process
- Describes basic approaches and techniques of File and Folder recovery process.
- Understanding Partition Recovery Process
- Describes most common partition failures and techniques of their recovery.
