Universal method for changing disc permissions?

[petehumble]

Hi,
I'm wondering if there is a way to turn off disk permissions at a universal/admin level so when I plug an external drive in I don't have to go into "get info" to do it. Im having issues with Avid media composer recognising drives via the interface which is how I need to navigate with this software. In teaching an Avid class and I don't want to have to go around to every students computer every time a new student plugs their drive in. I have 80 + students each week. (And I can't hand the admin password to them)

Thanks

A launchd job which will run when a device has been mounted. A job with the StartOnMount key set to true will be started whenever a device is mounted, in other words, when you insert a CD/DVD, connect an external hard disk or mount a virtual filesystem.

Info : https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man5/launchd.plist.5.html

Note : launchd does not report which device has been mounted.

Hmm, thanks for reply.
Although this seems way out of my league.
No idea where to begin, what any of this means or how to implement it.
Is there a non-computer science solution anyone?

I think this will do it, but don't run it until someone gives their opinion on it.

sudo chmod -R 777 "/Volumes/{disk name}"

Of course, substitute the {disk name} part with the drive's name, don't include the curly brackets. It'd probably only have to be run once or whenever there's a problem with it.

Are you the administrator for these computers? It might be useful to look at ways to administrate all these computers with something like Apple Remote Desktop or alternatives. The solutions are there it will only take a little trouble on your part. If the computers are networked and remote login is enabled you can ssh into the student computer and run the chmod command. With Apple Remote Destop and Automator it would be even easier to do this.

Yes, chmod would be the obvious command to use here but it would still have to be done on all the students computers manually. And what about the disk names. Are they all the same or do the differ? Are they provided by the teacher or do the students bring their own?

Hi,

I am the administrator but they're not networked.
I will see how I go with this. Thanks again, I appreciate the replies.
