defragmenting is like keeping your room tidy .. imagine you are in a big big bigggggggg room .. your physics note is in one corner.. your physics book is in another .. your physics tutorials is in another.. your pencils/pen is in the other .. why do you need to tidy ?
I rarely use defrag software because I separate frequently modified file into separate partition. Windows built in defragmentation is good enough for me, but to fully defrag the disk I still need O&O Defrag, with boot defragging I do not have to defrag the disk on other computer. Speeddisk for ntfs (windows 2000/xp/2003) is lame compare to speedisk for fat32 (windows 98).
its not the file that u have to sort.. every file have been broken into several fragment.. so everytime u copy/ install these file are scattered all over the hd, so the file become fragmented.. that is why it need to be defrag.. (correct me if im wrong)
So what good can i get from defragmenting my HD? Windows have a disk defragment thing already, right?
Defragmenting your hard disk improves its performance by arranging your data contiguously. This allows your hard disk to read data without seeking all over the platter. Yes, Windows XP comes with a built-in disk defragger. You can use that as well, although it seems to be slower and less advanced than third-party utilities.
Probably cause there doesn't seem to be a Lite version? What version are you using? Take a look here - http://consumer.diskeeper.com/diskeeper/diskeeper.asp?RId=1&SId=2&CId=13&pass=12672741
