Definitely worth a look if you're interested in tweaking. It may or may not effect non-Intel machines running Leopard as well. In conclusion, if you feel like your system has begun to crawl and you haven't done an erase and install recently, fragmentation free space in particular is a very real culprit to check. And for the price, iDefrag is an absolutely fantastic utility to have around. Highly recommended. Sounds neat, but I only have Leopard installed right now. I'll be keeping an eye open for iDefrag along with DiskWarrior I wish they at least made an announcement as to when DW will be updated.
Just to confirm I couldn't find anything definitive on the iDefrag website it sounds like iDefrag comes with a utility you can use to create a bootable CD that you can boot from to defragment your primary drive while offline, if you have Leopard installed?
Yeah, though obviously the machine must be able to boot from Tiger for that to work at all. I run iDefrag and DiskWarrior, like a religious freak, and, neither app.
That's what they claim in their FAQ. I haven't tested it, but iDefrag comes with CDMaker and you can use it to create CDs to boot from so that you can defrag your main drive. When you launch it, it asks you for a location to get the core OS X files it needs to run. They offer online, downloadable templates that are offered as choices when you launch CDMaker. When you first run Coriolis CDMaker, you will be prompted to choose the source for these files.
These files can either come from the Internet, where we have stored preprepared, tested templates, or they can be copied from your installation media. If you want to use your installation media, insert your media in your computer and Coriolis CDMaker should detect it. If you want to use Internet sources, make sure that you are connected to the Internet otherwise Coriolis CDMaker will not list any sources.
Which source should I choose? We generally recommend using an Internet source since they will have been tested the most.
However it is usually safe to use your installation media which will be the quickest option, especially if you have a slow Internet connection. Sources from the Internet are provided for your convenience.
The earlier templates are for a CD. They are not Universal, so you will need to pick the appropriate template for the architecture of machine that you have. You can find out if you have an Intel machine by selecting About this Mac from the Apple menu. If you see the word Intel in the description of the processor, you have an Intel machine. Note that the earlier templates may not work on the latest Apple Macs so you should either use a DVD template or create a template using the installation media that came with your machine.
If you have a machine that Apple has only just released, there may not be a template on our site that works as we may not have had time to produce one. In this case, try using your installation media that came with the machine. If you want to create a new template at a later date, there is a menu option on the Coriolis CDMaker menu. I have been running Leopard for about 4 months and work with large video files - a couple of weeks ago I started to notice that my HD would thrash alot even at idle sometimes even when I would be surfing the net.
Restarting the machine didn't help so I tried idefrag and although my system is not any faster save for iphoto! Space wasn't an issue since I still had about 20 GB left on it. I definitely think it helped. This reminds me of Windows When there's a market for this sort of tool, something is wrong with the OS. Thanks very much for this information DaedalusX. It's been very helpful. All versions of windows have fragmentation problems. All version of OS X do too. I usually just clone to an external drive, boot from that, erase the internal drive, and clone back to it.
If I am paranoid that day I make two clones for safety. It's interesting that people both believe it necessary and claim benefits from doing it. It is risky to defragment anyway: What if there's a power glitch?
What if the system crashes? What if the defragmenting tool has a bug? What if you inadvertently reboot? In some cases, you could make the situation worse by defragmenting. On Amit's recommendation I leave well alone, but I guess if some people really are seeing benefits then it may be worth their while to do it.
I can't help thinking that this should be a feature in disk utilities I mean, windows has one so why can't we? I just go by the vendor's recommendation in each case.
Apple says defragmentation should not be a problem and Amit's tests which are admittedly, on a relatively small sample seem to bear that out. Microsoft, however, provides me with a tool to do it, so I use the tool. I assume they know what's best for their own product. What I don't do is defragment weekly with a scheduled maintenance task, as I know some people do.
I run the analyser now and then and when it says "do it", I do it. When it says "you don't need to Asked if he saw any benefit from that, he was hard-pressed to say he did, and more-or-less said it wasn't necessary, and he did it because he liked doing it.
I think that's a bit crazy. I just follow the vendor's recommendations in each case and on OS X and Linux that means I do nothing. If others are doing it and either seeing benefits or believing that they are then good luck to them. Retrospectively, I like this way of creating the disk image to work from way better. I found more information on making a boot disk for my MacBook here. I spoke too soon. It started copying but in the en quit with an error: I'll paste it here: The first error is from a CD and is too big , the second error is from the image that it cannot copy the usbmodem thing, which I can copy manually with no problem.
Update: I managed to fix my partition by skipping cdmaker altogether. Then I booted OSX and resized it back to full size. The managed to move the files that Boot Camp assistant couldn't. So when BCA tried now it worked.
I've tried carbon copy cloner as described and still no dice, error in the very last second when making that copy, CCC said it wouldn't be bootable, I don't know whether thats a problem to start with. I've also tried the method from the insanelymac forum link, and that didn't work either this time it wouldn't even pretend it tried.
Maybe that could be the problem Can you think of anything else? I could post a console log if that helps? Thanks for the infos, unfortunately I'm away with a corrupted partition table and I don't have my leopard disks with me, any solution? I used machacha to get the. I mounted the new image and in the folder Applications I copied a full copy of iDefrag 5.
I burned the image in a DVD i didn't have any cd :D 6. I reboot and boot from the new CD by pressing letter C 7. I also wanted to be able to play internet radio streams. Being a bit of a self- and spouse-induced tightwad I decided to buy a broken Roku Soundbridge M and fix it.
The most obvious problem was the VFD display wasn't working. The previous owner also stated "there might be other problem besides display connection". Also, the broken M had no remote. I decided to take a step-wise approach and fix the display problem before I bought a new remote in case the unit was beyond repair. The display was dead as described. I figured the unit was getting power as one of the LEDs for the ethernet came on. When I unscrewed the WLAN pcb from the mainboard it just fell off leaving both parts of the connector on the mainboard.
The solder joints of connector on the WLAN pcb side had cracked and failed. I cleaned up the pins of the connector socket and soldered the connector socket back onto the WLAN pcb.
I heated up each each pin at a time with the soldering iron set to 15W to re-melt the solder. I repeated the process a couple of times to make sure I didn't miss any pins. The result is not the prettiest job I melted some plastic in the process: see image below but at least the socket is now firmly attached.
I connected the WLAN pcb onto the mainboard and screwed it back in place. The next thing I had to address was the display, in particular the display connection.
Except for the display, the mainboard and pcbs look very similar. The correct orientation of the display connector was obvious and the fact that the display was connected incorrectly was even more obvious. I connected the display correctly see image below and powered it up.
Immediately the display came to life displaying a startup message. I plugged in the ethernet cable, powered it up again and it detected my music collection advertised by my server. The display of the M works perfectly now. Suddenly my gamble seemed like it might pay off. Diagnosis redux I then decided to try to go back and work out where the problem lay.
I removed the WLAN pcb to mimick the faulty solder joints.
