The pertinent filesystems (particularly the boot and root partitions)
are ext3. I also have a second hard drive with a single large ext3
partition, but that isn't involved.

I can try that, but I'm a little concerned about rebooting too often. I
use DHCP and my mail server needs to know my IP address to let me send
messages. If I reboot and get a new address, I have to let my mail
server admin know so he can change the tables on his machine. I don't
want to do that very much.

That's a non-starter.

I agree. This is likely not a scanning problem.

They were included on my "to" list.
