Mac OS X 10.2: Directory Issue Verification or Repair Is Not Part of Installation

When installing Mac OS X 10.2, disk directory issues are not checked for or repaired. Use Disk Utility's First Aid feature first if you think there may be a directory issue. Catalog file issues, B-Tree errors, mount check errors, and overlapped extent allocation errors are examples of directory issues.

Important: Performing an upgrade or Archive and Install installation when there are unresolved directory issues can make the issue worse, and possibly lead to data loss.

Reinstalling or updating Mac OS X 10.2 does not resolve disk directory issues (unless you perform an erase-installation). Use Disk Utility's First Aid feature to verify or repair the Mac OS X volume first, unless you intend to erase the volume.
