Spotlight not indexing: Some users have had an issue where one or all disks in the system will not get indexed for spotlight searching. This has occurred for users with past updates and other software installation, has occurred for some uses with the recent 10.5.6 update.

Some users have suggested adding the affected disks to the "Privacy" list for Spotlight, since this technically should delete the spotlight index on the drive. Removing the drive from this list then should allow the computer to remake the index. However, this does not properly occur in some cases. In order to fix this problem, users should manually reset the spotlight index using the terminal.
Fix: Manually reset spotlight indexing. Open the Terminal application and at the pormpt type the following command:
* sudo mdutil -e -i on
With this text entered (and ensuring a space is after the last character) drag the mounted disk that will not index to the terminal window, and the command should complete with the file path of the disk, as such:
* sudo mdutil -e -i on /Volumes/diskname/
Then press enter, supply the administrator password, and the index should be rebuilt.
