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.
