Why? This isn't a FAT partition that gets screwed up at the drop of a
hat.

Perhaps. But if you look at the system and the fsck command, you will
see that you can set the number of reboots or time before the command
runs. I'm not sure what the max is, but what if you could set it to 100
reboots, or 500 days? As long as it is still running and you aren't
getting any errors then the file system is fine.
One of the nice things about linux is that with regards to the file
system and the way it logs things, you would know long before there are
any real problems.

Depends on what it's doing. If there is a lot of disk activity, then I
wouldn't take a partition off-line. That a way to have a disaster for
sure. As I've already mentioned, it isn't something that is really
required with todays file systems. Well, except for the m$ ones..
