If the snapshot volume was made smaller than its origin, which is a common practice, this may render the snapshot inoperable. Snapshots can be useful for backing up self-consistent versions of volatile data such as table files from a busy database, or for rolling back large changes (such as an operating system upgrade) in a single operation.
Applying the scheme discussed above on a fairly modern Windows-based system typically results in the following drive letter assignments: A: — Floppy disk drives, 3 + 1 ⁄ 2 ″ or 5 + 1 ⁄ 4 ″, and possibly other types of disk drives, if present. B: — Reserved for a second floppy drive (that was present on many PCs). C: — First hard ...
This simplifies data recovery if a PV is lost. In the 2.6-series of the Linux Kernel, the LVM is implemented in terms of the device mapper, a simple block-level scheme for creating virtual block devices and mapping their contents onto other block devices. This minimizes the amount of relatively hard-to-debug kernel code needed to implement the LVM.
GParted is used for creating, deleting, [3] resizing, [4] moving, checking, and copying disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). It can also be used to format a USB drive.
The total data storage space of a PC HDD on which MBR partitioning is implemented can contain at most four primary partitions, or alternatively three primary partitions and an extended partition. The Partition Table , located in the master boot record, contains 16-byte entries, each of which describes a partition.

ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

FIPS (First nondestructive Interactive Partition Splitter) [1] - is an MS-DOS program for non-destructive splitting of File Allocation Table (FAT) hard disk partitions. Splitting partitions is an alternative to deleting the partitions and creating new ones using software such as fdisk , the advantage of which is that the data is not lost.
