I run what I imagine is a fairly unusual disk setup on my laptop,

I use the raid1 as a backup. The raid1 operates normally in degraded

then fail/remove the external hdd.
This is not directly related to your issues here, but it is possible to
make a 1-disk raid1 set so that you are not normally degraded. When you
want to do the backup, you can grow the raid1 set with the usb disk,
want for the resync, then fail it and remove it, then "grow" the raid1
back to 1 disk. That way you don't feel you are always living in a
degraded state.
