Tech blogger Phil Windley grew tired of trying to eject his external back up disk, first the suggested Apple+E way and then by yanking a cord, just to see that ominous red stop sign of warning every day, even when he knew his disk operations were (or should have been, at least) done. His suggestion for others suffering from clingy back up drives: Parse together a terminal command similar to the one below (substituting name and other portions for whatever fits your system):
Mac OS X tip: Nothing's more heartbreaking to a keyboard lover than discovering that a common application action is lacking a keyboard shortcut. Luckily OS X makes it wildly simple to add new shortcuts for any action available in the menu bar. Here's how it works:
