Writing at the Help Desk Geek web site, which covers "Computer Tips for IT Pros," systems analyst Aseem Kishore discusses the technical merits of defragmenting, while acknowledging the ongoing debate about its worthiness. Following his investigations and research, he summarizes that "PerfectDisk has made me a believer in defragmenting again and I think it will make a big difference if you are a heavy PC user. It's great for IT environments." You can read the entire post here.
If Aseem doesn't make you a believer, surely Shrek can...or at least put you in a good mood.
