Well, as of 10.4.3, it's probably overkill to "deactivate" indexing on the drive. Instead, I'd turn indexing on (with Spotless, if it lets you), and then add the drive to the Privacy tab. In 10.4.3, that'll disable indexing, searching, and we'll maintain the setting, too.

(Note that we'd also maintain an "off" setting, so I'm not sure why things would turn on again with Spotless, which only manipulates the plist. Have you found any repeatable pattern that'll do this?)
