How do I stop my Mac waking up when I remove or switch off a USB hard drive?

    The default behaviour of Macs seems to be to wake up from sleep whenever a USB device is disconnected or switched off. This is not very helpful for how I like to operate.

    I want to keep most of my files on an external USB drive without power-down feature so that I have fast access to them at the click of a mouse button (don't want to wait for the drive to spin up as can happen frequently if your drive has the power-down feature). However, I like to sleep my Mac several times a day, and when doing so would like to switch off the external USB HD until I get back.

    So you see the annoyance, but perhaps there is a way to disable this wakeup feature of Leopard. I'd be happy to learn it from you! PLMK

    I don't think this is possible, but it has annoyed me too. I sure would like to know if there is a way to do this.
