Problems changing drive icon

Solution 1:

For anyone coming to this page for help with changing the icons of applications, it might be helpful to know that a similar solution is needed.

Select the Application you wish to change the icon of, press cmd i, and look at the bottom of the window. Change "everyone" to read/write and then proceed to drag and drop your icon on the applications icon within the info pane. Don't forget to change the permissions back to read only for "everyone" when you're finished.

Solution 2:

Did you click on the icon to select it before pasting? I found I needed to do that or it would ignore my paste.
