Re: external hard drive permissions issue

What I would do is use disk utility to create a blank disk image on the drive and select encrypted on it, when it goes to create it, you are prompted to give it a password. The disk image cannot be mounted with out the password (so make sure you uncheck the box that says remember password). Make sure that you give the disk image plenty of space for your video. Just make sure that you unmount the disk image when you are finished.

I do this as a way to keep certain files secure like financial files, a document containing all my user names and passwords for different sites, like the bank, car-payment site, credit card site, etc because of course every place has different requirements for user names and passwords so you can never use the same one on all of them. So now I only have to remember only one password.

Hope this helps.
