I bought the new NW-A55L and I noticed that it rebuilds the database every time it starts up.  That's fine when the database is small, but mine is going to get relatively big - I'm at least going to have around 230GB which looks like it's going to add at least 30 seconds to the start-up.  It's not as if there's any good reason to assume the database has changed every time the device is turned off, so I'm hoping this isn't a major design gaff and that it can be turned off and rather done on demand, as the A105 allows.  Is it possible to disable this rebuild on start-up?
