When trying to index a hard disk, sometimes an error message appears saying the index stopped because there is not enough room on the disk. However, the disk has several megabytes of space available.

Also, Sherlock does not correctly update the index files under the Find By Content option. After deleting the FBC Indexing Preferences file, it still does not update the index files.

Sherlock 2 sometimes erroneously reports that the disk is full when there is sufficient room. If Sherlock encounters other disk errors, it may report the issue as insufficient disk space.

Since the Find by Content indexing relies upon the integrity of the hard disk, run Disk First Aid to verify that it is free from errors. Extensions or control panels may cause interference with the indexing operation, so check for extension or control panel conflicts or issues.

If Sherlock cannot properly index the hard disk, you can eliminate the index files and reindex the hard disk which creates new indexes. Here are the steps:

1. Quit Sherlock.

2. Delete the file named FBC Indexing Preferences; it is located in the Preferences folder within the System Folder.

3. Open Sherlock and click More Choices to enable a second search criteria.

4. In the first criteria line, set 'name is TheFindByContentFolder'. In the second criteria line, hold down the Option key to select visibility from the popup menu. The second criteria line should then read 'visibility is invisible'.

5. Click the Find button.

6. Select the found item in the Items Found window.

7. Choose Move To Trash from Sherlock's File menu. Click OK in the resulting dialog box; the item is deleted immediately.

8. Choose Index Volumes from Sherlock's Find menu.

9. In the Index Volumes window, select the desired disk for indexing, then click Update Index.

10. Click Update to index immediately, or Schedule for indexing later.
