Vanishing ice Posted June 15, 2007 Share Posted June 15, 2007 I think my hackintosh's hard drive needs defragmentation. But I don't have another system installed in a separate hard drive. How can I do that?? Link to comment https://www.insanelymac.com/forum/topic/54027-defragmentation-of-os-x-hdd/ Share on other sites More sharing options...
AndyHughes Posted June 29, 2007 Share Posted June 29, 2007 The file system that Mac uses automatically defragments as it writes. Its hard to conceptualize, but its the sane with linux. It just doesn't need it. Link to comment https://www.insanelymac.com/forum/topic/54027-defragmentation-of-os-x-hdd/#findComment-397867 Share on other sites More sharing options...
frizbot Posted June 29, 2007 Share Posted June 29, 2007 Unless the drive is nearly full. Even then, defragmentation isn't terribly important. iDefrag, TechToolPro, and IIRC Diskwarrior will help, but they cost money. The system does have basic drive optimization features already included. Next time, make a separate boot partition.

Synaesthesia Posted June 30, 2007 Share Posted June 30, 2007 Yep, OS X automatically defrags for you. Best thing to do is just to keep some free space,(if possible). It improves performance. Also, try running the optimisation scripts in onyx, Link to comment https://www.insanelymac.com/forum/topic/54027-defragmentation-of-os-x-hdd/#findComment-398119 Share on other sites More sharing options...
Chrysaor Posted June 30, 2007 Share Posted June 30, 2007 Automatic defragmentation only works for files that are currently not in use and under 20mb.

frizbot Posted July 1, 2007 Share Posted July 1, 2007 Defragmentation is generally a non-issue. If anyone knows of a free tool to use under OS X for it, something open source maybe, then it's interesting. Otherwise it isn't something to bother with paying for or pirating.

stacman Posted December 16, 2007 Share Posted December 16, 2007 You guys are perpetuating a myth. Download any defrag utility and look at the map of how your disk space is utilitized. Look at the list of files and how many fragments they are in. Also realize that OS X uses the worst method of memory paging it possibly could, which is by individual files that it creates and deletes as needed (Windows 98 anyone?). This means that you DO NEED an external utility to clean up the mess. Utilities such as iDefrag, Techtool Pro, and Diskwarrior will do the trick. They will defrag files AND free space, as well as relay out the files on your drive to make for better reading.

frizbot Posted December 17, 2007 Share Posted December 17, 2007 You're bumping an old thread for no reason. "This means that you DO NEED an external utility" does not follow from the rest of your post. Windows still uses dynamic size VM files by default.

ViseMoD Posted April 18, 2008 Share Posted April 18, 2008 I've tried to use iDefrag but without success - it just freezed each time I started it. After a while I read that I have to run iDefrag from a boot disk. I've dowloaded Coriolis CD Maker and create a CD with Mac OS 10.4.8 downloaded from Internet and iDefrag as well. However, I can't boot with with this CD on my Intel PC - it seems that there is no boot section on it. Could anyone help me with this issue?

knewsom Posted April 18, 2008 Share Posted April 18, 2008 Actually, what DiskWarrior does is analyze and repair the file directory, it doesn't actually move around all the different files on the drive, just updates the OS so that it knows where everything is much easier. ...but it can make a world of difference for a computer that's hurtin'! I'd definitley give DW a try, it comes with a boot disk.

Espionage724 Posted April 18, 2008 Share Posted April 18, 2008 So what would the best tool to get to optimize disk performance? I would like to "buy" it later on.

macgirl Posted April 18, 2008 Share Posted April 18, 2008 isntead on buyin defrag tools you better buy faster disk, there is no "significant" performance gain after defrag.
