How to Defrag a Linux Drive
Defragmentation is the process of rearranging files on a hard drive so they are in contiguous order. This means that every file on the hard drive is set up in a line, one after another. Defragmentation improves file access (also known as "seek") times by minimizing the amount of distance the drive head has to travel when reading a file. Defragmenting a Linux hard disk can be done quickly using the built-in "e2fsck" command.
