iPhoto locked on burnt DVD but not on comp or backup?

[Frznrth]

Hi
I wanted to backup my iphoto library so I burnt it to a blu ray DVD. When I tried to open it to check I get the Iphoto locked error message. But it isn't locked when I open it from my mac. I also saved it to a backup hard drive and it works fine from that. Why would I have trouble just with the DVD? - I just dragged the library to the DVD and burned. I have a couple of libraries so I need to choose the one I want.
Thanks for your help

That error message it because iPhoto library is in DVD and it cannot be modified. DVD is fine for archival purposes but you have to use iPhoto library from hard drive or SSD.

Thanks. It is for safe keeping. I only tried to open it to check. I don't have enough space to put it on my Mac. Don't suppose there is a way to check without doing that?

Why is getting it off my DVD different than getting off an external hard drive? Just curious. Thanks again.

Easiest way is to copy it to external hard drive, it will then open without problems.

Alternatively you can right click it and choose "show package contents", it will show you all the folders and files within the iPhoto library.

As for why Apple designed it this way I am not certain, my guess is that they wanted to make it as foolproof as possible.

thanks. I'll try the right click. I'm using Blu Rays as I don't trust external drives anymore. Two failed on me in one week.

So in theory I should be able to use the DVDs to restore iPhoto to a new Mac if needed? - god forbid.

Thanks for the help.
