Do you have your USB hard disk mounted using the device name (/dev/sdaX)
or a disk UUID (UUID=blahblahblahblah) ?

That should only make a difference when powering on with the adaptor
present, not when plugging it in when running, but using UUIDs
eliminates the issue of the device names ever changing.
