Its Linux Wednesday! This post is slightly later than usual, but I was upgrading to Xubuntu 8.04, review next week :) . Anyway, today I will be telling about a small application I run once month, called SCRUB. This application is the closest thing I have found to a defragment software for Linux. Basically, its a Disk scrubbing program. This utility writes patterns on files or disk devices to make retrieving the data more difficult. It operates in one of three modes:
1) the special file corresponding to an entire disk is scrubbed
and all data on it is destroyed.
2) a regular file is scrubbed and only the data in the file
(and optionally its name in the directory entry) is destroyed.
3) a regular file is created, expanded until
the file system is full, then scrubbed as in 2).

SCRUB on my PC takes about 20minutes to complete, but will change depending on the speed of your PC and your HDD size. I have noticed speed increases on my PC and it has in the past cleared some room on my HDD. I would recommend you download this application, and run once a month to make sure your PC is running at its best.
