I'm having a problem where I have all of my music on an external Lacie D2 drive. The drive is quiet but makes a fairly audible high pitch noise when the drive is spinning. So I like to turn the drive off when I go to bed. Problem being... when I do this iTunes reverts it's Library location back to the default place ~/Library/iTunes/ etc. So when I wake up in the morning and turn my drive back on everything in iTunes plays fine. But I'm constantly forgetting to switch locations back to my D2 drive. So any time I add new music to my Library the file gets copied to my internal hard drive and not to the external one. Is there any way to stop iTunes from revertting back to default location without just quitting it before I shut my drive off and then not running iTunes before I turn my drive back on? I hope I made my problem clear enough to understand.
