Disk Label
|
Detailed explanation-1: -A special area of every disk is set aside for storing information about the disk’s controller, geometry, and slices. That information is called the disk’s label. Another term that is used to described the disk label is the VTOC (Volume Table of Contents). To label a disk means to write slice information onto the disk.
Detailed explanation-2: -Type 82 is a Linux swap partition, and type 83 is a Linux data partition. There are approximately 100 different partition types defined. The second disk is shared between several operating systems, including Windows/XP, hence the presence of Windows NTFS (and possibly FAT32) partitions.
Detailed explanation-3: -The disk stores the information about the partitions’ locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct “logical” disk that uses part of the actual disk.
Detailed explanation-4: -On a Linux system, disk partitions are given a device name such as /dev/sda, /dev/sdb, /dev/sda5, etc. Basically, sdX (with X being some letter), and sometimes a number on the end.
