Think of your hard drive as a storage bin and think of your files as all of the stuff that you want to store in that bin, when you create a file or copy one over etc the file is written to your hard drive. Now there isn't always enough space to write the file completely in one area of the drive so the file is split up into chunks of data that make up the file. Let's use a Microsoft Word document for example: some of the data that makes up your word document is stored one location and another chunk of data that makes up your word document is stored in another area around the platter(s) of your hard drive. As you continue to add stuff to your storage bin (files to you hard drive) the computer just sticks the chunks of data from each file wherever they'll fit. So now your word document isn't actually in one peace but in several chunks of data spread through out your hard drive. This is known as fragmentation. So now suppose you want to open up that word document when you do the computer has to search your hard drive for all of the chunks of data that make up your word file. Not only does this take time but it causes the read/ write heads to your hard drive to do a lot more work then they have to. To defragment your hard drive is to put all of these chunks of data that make up your word document to example in one location on the pladder of the hard drive so that when you go to open it the computer doesn’t have to search all over the hard drive for the chunks that make up your word document. A disk defragmenter defragments your hard drive.

I would defragment once a month, you might even see a small speed increase if you do although it won’t be anything major.

Probably since defragging is a windows problem for the most part, no such thing on many of the the other OS's that use better filesystems

Yeah, defragging can create a world of difference in hard drive speed. It has no effect what so ever on your processor speed though.

I wouldn't say it's really a world of difference.. but yes.. it can make accessing a bit quicker.

If you've never done it before, do it now!

Any file system suffers from fragmentation. Try O&O Defrag.

Not exactly, at least not what FAT32 users are used to, journaling filesystems for the most part eliminate it, there isnt a defrag utility for it, no need.The only place some fragments may happen is within a file itself, and since POSIX based OS's treat evrything as a file, its prettymuch a non-issue.

I just ran reiserfsck on my primary partiton as well as a check on total thruput, right now its 77% full,0.45% fragmented, and has had 274GB's of thruput since last reboot which was about 45days ago.Its never been defragged and I dont think a defrag program even exists for it.
