I changed the iDisk icon, and it shows up everywhere I expect it to but the sidebar. I suspect that this is because in the sidebar, iDisk has a function associated with the icon (the sync button to the right of the icon). Also, you cannot drag iDisk out of the sidebar; you either have to right click it and select remove from sidebar or uncheck it in the sidebar tab or the Finder preferences. I am looking for a way to change the icon of Remote disk, and other volumes that act the same way as it. If you right click remote disk and select get info, a small screen with a minimal amount of information comes up. When you drag a icon into the remote disk icon (a blank CD) you get a little green + icon, but if you let go of the mouse button, nothing happens. Doing the same thing to a hard drive or folder would change the icon, but not for Remote Disk, Computer, or Network. Are you aware of a system folder that holds the icons for these volumes that I could look into. I could probably drag my own icon into the folder, rename it to what the original icon was names, and that change would be reflected systemwide.
