People who don't know about menus shouldn't really be mass-deleting things yet. Alternatively, add a button for "Help! -The Computer lost all my stuff".
A brief Google search confirms that "lost my files" wasn't solved in 1995. I'm pretty sure those aren't all Mac users. Even if 90% are due to other issues, there are many people who would like their data back. I believe many are due to the ease with which a user can delete files compared to the difficulty they experience when restoring them.
The dangerous button is much easier to find than the fix-it button. One is right there, with your files. The other is someplace else, related by metaphor alone. Once you have selected the recycle bin you then have to search through your very long deleted file list, select the file you want, select another button to restore it (which appears in the same place as a different button existed before selecting the file), and then navigate back to the place you were expecting the file to be. We're talking about users who can't figure out a menu, but they can perform this multi-step task. I can easily see a new computer user screwing this up.
Next time you look at the context menu of a removable drive, see that "Format" is right there with the eject menu item. One should be used every time you use the drive, the other very rarely and only when you're sure. The latter should be removed to a sub-menu under "advanced", or similar.
Myself, I'd make it harder to delete things and a lot easier to find them again.
