![]() ![]() One of those solutions was to use an application such as iDefrag that could "move" files in order that he would have enough contiguous free space to create the partition. Please note that the OP was given two solutions to resolving his problem of not being able to create a Boot Camp partition. In a commercial environment ( where productive time is a valuable asset ) then defrag can make a difference, especially in the area of employee satisfaction D I am not suggesting that you can turn this into a general statement, but you can not neglect the findings either.Īll I am saying is that in my personal environment, I don't care that much as long as my machine performs well. That indicates that on this particular MB, we achieved an increase in performance ( of which the loading of spreadsheet is the only relevant one ) When we tested defrag on the MB, we had the following situation: MB 2.26 Ghz, 2 GB RAM, 250 GB/5400 rpm, OS X 10.5.8, 7% fragmentationģ x cold boot to logon screen, no apps loaded at startup = 38 seconds, after defrag 26 secondsģ x load openoffice ( cold boot ) = 12 seconds, after defrag 9ģ x load a 7280 KB spreadsheet ( cold boot ) = 18 seconds, after defrag 12 seconds As such, one of the tests was a defrag on our test MB.ĭuring these 8 months a lot of apps and data have been installed on the MB and removed, 4 x OS's upgrades, you name it. ( we use PerfectDisk )įor 8 months now, we are investigating to replace the winxp machines with MB's and we are running all sorts of tests to assess the economic and techical feasibility of switching. Frequent defragging the disk is required to keep the system running at top speed. We currently have a sales-force on the road with winxp machines running an application using a MySQL database and lots of large spreadsheets, which change daily. Though it won't optimize it.Maybe I can quickly share some ' live ' results on defrag Moving all of your data from one drive to another will automatically defragment your data. wipe clean) the old drive and start over with it. Of course, another option, instead of defragmenting your hard drive, is to simply purchase a new, bigger, hard drive copy all of the data on the old drive to the new drive, and then reinitialize (i.e. Coriolis Systems offers free software to allow you to make a boot CD-ROM to run iDefrag from, but using iDefrag this way isn't as safe as using it while booted from another hard drive. "The downside to iDefrag is that you can't do a comprehensive defrag without booting from a volume other than the one that you are defragmenting. I think theologians call that 'invincible ignorance.' It is now a widespread form of the pollution of information space." It is an example of ignorance that is not able to be removed by any amount of evidence. "The claim that installations of Mac OS X on HFS+ volumes do not fragment is a myth believed by people who do not have disk optimizers that allow them to see how much fragmentation their disks have. He doesn't need people preaching to him how defragging is unnecessary in OSX when in fact it is when you fill up over 80% of the hard drive. Just let the man defrag his computer in peace. But it's wrong to conclude that defragmenting doesn't help at all on a Mac. If you always keep enough free space on your volume(s), the operating system will probably do a good enough job at minimizing fragmentation. I've been meaning to install a copy of OS X on that drive, boot to it, and defrag the 1st HD, but haven't gotten around to it. ![]() ![]() I've used iDefrag on my 2nd HD (which holds my games) and it does seem to make load times snappier on large games. I thought 10.4 was to blame, but I eventually formatted and started over without the HD being full of stuff, and the speed was much better. I believe the result was that the updated system files ended up fragmented whatever the case, Mac OS X ran very slowly. I upgraded from 10.3.x to 10.4 with very little free disk space. I have had a Mac OS X system get really slow due to fragmentation. If you've run your system for a long time without a full defragment, in particular with not much free space, fragmentation can get progressively worse. If it did, we'd end up waiting an unbearable amount of time for every little disk write (there's too much involved in making sure absolutely no fragmentation occurs). While it's true that Mac OS X does a good job at minimizing fragmentation, it can't stop it entirely. ![]()
