Several people have answered "no, it's not possible in all cases." Brian even gave you sample code for the only case where it is possible (canceling idle sleep). Just because the answer isn't what you would like doesn't mean that people aren't answering. This email sent to site_archiver(a)lists.apple.com

For the kernel, you will need to be an IOKit driver to get power events (there may be someway to get them from a "normal" kext as well). With some basic searching on Google you would have found: http://developer.apple.com/documentation/DeviceDrivers/Conceptual/IOKitFund… /apple_ref/doc/uid/TP0000020-SW3 However, it does not look like you can prevent sleep at the kernel level (even idle sleep) when receiving these events. You may have to resort to some hackery to tickle an event stream to trick the system into thinking it's not idle - thus preventing idle sleep. Probably the easiest thing to do would be to have a user-land daemon launch when your kext loads and you can then use the solution I gave in my previous email. When your kext unloads, have the daemon quit. This email sent to site_archiver(a)lists.apple.com

Any ideas? >From a shell prompt, I would cd to the destination disk. Just as an experiment, I would do: note the single quotes. No backslashes are needed. See if you get an error with the touch. (touch, in this case, will simply create an empty file with that name.) If the touch works, then the error that you are getting is misleading. I just did it on my laptop and it worked. It is formatted with Mac OS Extended (Jornaled) as well. If the touch does not work, then I would redouble my check to make sure the destination disk is formatted like you think it is. Probably experimenting around with touch might lead you to figure out what is really wrong. As far as getting around the problem, if the touch works, then I would copy the file (don't move it) and you can rename it on the copy. e.g. cp '/source/5 - Oxygene XII - Concert Theatre Marigny 2007.mp4' 'dest/ temp.mp4' I would use single quotes and not backslashes. It just seems easier to me. Once it is where you want it with the name that you want it, then delete the source copy. Move of a file from one file system to the other essentially does this same sequence. Maybe you do not have permission to delete the source copy or something like that. It sounds like the invalid argument is coming from someplace unexpected. This email sent to site_archiver(a)lists.apple.com
