Spotlight State Problem

[joe3zz]

I am backing up my Macbooks HD nightly using a Smart BU. When I initially created the partition on my WD 250 GB USB drive, I added it to the privacy tab on Spotlight.

The problem is, the drive will disappear from Spotlight, and if I try to add it in again, by dragging it or any other means, it cannot be done. If I erase the partition, and add it back to the privacy tab I can do it, but the problem will happen again after a few backups.

I've even tried letting Super Duper disable_spotlight script after the backup, but that does not help either.

I have two external USB drives, and use one to backup the other with Superduper, without a problem. It only happens on my Mac's drive.

Any ideas?
