You're absolutely right about it not being necessary to sync before you
unmount, but what I meant was that my experience with IDE hot swapping has
been pretty risky when it comes to crashing your entire system as soon as you
pull a drive. You'll want to sync for the sake of the other drives in your
system so that if your system does crash, those drives will be in a clean(er)
