I noticed my "spotlight" icon has a pulsing dot in the center of the magnifying glass icon....when I click on it there is a progress bar and it is perpetually "indexing" my hard drive. Whats this mean? Is my HDD going to fail? Its been going on like this for months. Running Drive Utility, Techtool or Disk Warrior doesn't fix it. I fixed permissions and repaired the disk off the Snow Leopard book disk, problem persists.
