I have been trying to look for a defragger that "works" and has good features. I really like background/automatic defragmentation but its not a must. File placement is also preferred. I have been picking my choices by the disk defragmenter poll located here The most popular picks are: AusLogic Disk Defrag Windows built-in defragmenter Diskeeper Home/Pro PerfectDisk Power Defragmenter GUI with contig.exe O&O Defrag Pro DiskTrix UltimateDefrag JKDefrag Now i will write why or why not i don't want to use them and hopefully someone can pick one for me. AusLogic Disk Defrag: Didn't try it but looking for one that does more than defragment. Windows built-in defragmenter: Why pick this when there is better free ones? Diskeeper Home/Pro: Using it right now and like the automatic defragmentation in the back ground but thats all it seems to be good at. The I-FAAST seems to be useless and the Frag Shield's ability is impossible to track. So i am looking for one that will have useful features and not features there for marketing. PerfectDisk: Seems the best of the bunch yet when i run the smart placement defragment it gives up after 10 mins on both of my computers. Maybe a bug in the build? Or it cannot handle big files at all?. Power Defragmenter GUI with contig.exe: Tooo simple, would rather use jkdefrag. O&O Defrag Pro: Haven't tried but sems very good from the description because it has the automatc defrag of diskeeper and the file placement of perfectdisk. Best of both worlds. If it is able to finish a whole defrag without giving up like perfectdisk than i may use it. Obviously not just putting features for marketing because it does not call its file placement, SmartPlacement, or its automatic defrag, InvisiTasking. DiskTrix UltimateDefrag: It actually seems really complicated with all its options and the GUI doesn't help it at all. But if it can defrag and optimize good without a ton of tweaks than who cares what it looks like. JKDefrag: My favourite freeware choice and does the job but want something that can show and reccommend whats wrong with my disk instead of just defragmenting it and optimzing it straight away. Im not good at reading logs . O&O seems to have the features i want and so does perfectdisk if it worked. Although the stealthpatrol in perfectdisk would never run after leaving my computer inactive for hours, so an on-the-fly one would probably be better. Your opinions or favourite defraggers are appreciated . And don't redirect me back to the poll thread for opinions becuse the only opinion there is that it works with FD-ISR which doesn't exist no more .
