I'm getting the following in my system log:

Oct  2 12:43:53 tehogee smartd[2509]: Device: /dev/sda, 1
Currently unreadable (pending) sectors
Oct  2 12:43:53 tehogee smartd[2509]: Device: /dev/sda, 1 Offline
uncorrectable sectors

many, many, of them
/dev/sda contains my /boot and / mounts
/home is mounted on a separate drive

How can /dev/sda be "Offline" since this is the machine I'm typing
this message on???

Is FSCK the right tool for this? If so, I can't figure out how to
run it on /dev/sda since, if I read correctly, the mount has to
be unmounted - presumably, I need to do this from a rescue disk?

I've searched on this in the past, but was never able to find a
good explanation of how it's donw. If someone can give me one, or
point to a good document, I would be grateful

you can run fsck on a read-only partition, it doesn't have to be
unmounted.  Reboot into single user mode, and remount each partition
on /dev/sda readonly:
mount -o remount,ro $mountpoint

and then you can fsck them.  Good luck, hope you have backups.
