As you use Linux File Recovery and read this user manual, you will come across terms with which you may not be familiar. So we've compiled the following list of definitions as follows:
Dynamic Disk
A Dynamic disk is a physical disk that provides features that basic disks do not have, such as support for volumes spanning multiple disks. Dynamic disks use a hidden database to track information about dynamic volumes on the disk and other dynamic disks in the computer. Dynamic disk management is a data/Hard Disk management method on Microsoft Windows platforms, first introduced with Windows 2000 Operating System. The basic concept was put to use on UNIX platforms years earlier. There are five types of Dynamic volumes: Simple Volume, Striped Volume, Spanned Volume, Mirrored Volume, and RAID-5 Volume.
HDD
Short for "Hard Disk Drive", a HDD helps to manage the transfer of data to and from your computer's Hard Disk. Because these two items always come as a single unit and "Hard Disk" are usually used to refer to the same thing.
Bad Device
This is the storage device that contains the data you want to recover. A Bad Device can be any disk-like storage media, such as your computer's Hard Disk, an external HDD, Flash card or any other form of removable media.
Good Device
This is a storage device that is in perfect working order onto which you want Linux File Recovery to save the data recovered from the Bad Device. The Good Device may be located on the computer on which you've installed Linux File Recovery (the "host" computer). The Good Device can be any of the storage media listed for the Bad Device. The Good Device is used to save recovered data from the Bad Device to.
Host Computer
This is the computer on which you have installed Linux File Recovery. The Host Computer is used to recover the lost data from the Bad Device, which should be connected to the Host Computer as an additional drive (second, third or fourth - in addition to the existing drive(s) on the Host Computer). This means that the Host Computer will have at least two disks: Bootable HDD, which is used to boot Windows from; The Bad Device set as an additional drive.
If you are using removable media such as a Zip disk or Flash card, you should insert the device prior to launching Linux File Recovery.
Ext2fs:
an extensible and powerful file system for Linux. It is also the most successful file system so far in the Linux community and is the basis for all of the currently shipping Linux distributions.
Ext3fs:
The ext3 or third extended file system is a journalled file system that is commonly used by the Linux operating system. It is the default file system for many popular Linux distributions.
Blocks:
The basic unit of storage on a logical drive. A cluster is a group of sectors. One cluster is allocated to a single file only. Cluster sizes can vary from 512 bytes to 256k bytes, depending on the particular file system and the partition size.
Super Block:
The super block describes the overall structure of the file system within the logical volume. It contains the file system name, the size, the pointer to the inode and free block lists, and so on. The super block is used to keep track of the file system state during operation
Inode:
Inodes are data structures that contain information about files in Unix / Linux file systems. Each file has an inode and is identified by an inode number (i-number) in the file system where it resides. inodes provide important information on files such as user and group ownership, access mode (read, write, execute permissions) and type.
Partition
A partition is a logical division of a Hard Disk that creates the impression that you have more than one Hard Disk. If you want to run two different Operating Systems on the same Hard Disk, you should create a two-partition drive when you format the disk. Partitioning a disk is just a way to divide it up into independent sections.
