If you want to check a Mac OS X 10.4 Tiger volume with Disk Utility First Aid in Mac OS X 10.3, make sure that you use Mac OS X 10.3.9. Earlier Disk Utility versions will report false issues with the Mac OS X 10.4 volume, such as the following:
** /dev/rdisk0s7 (NO WRITE)
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
** Checking multi-linked files.
** Checking Catalog hierarchy.
** Checking Extended Attributes file.
Invalid leaf record count (It should be 2 instead of 21)
** Checking volume bitmap.
** Checking volume information.
** The volume [Mac OS X Tiger] needs to be repaired.
For an accurate Disk Utility report, only check Mac OS X 10.4 volumes while started from a Mac OS X 10.4 volume or Install disc, or while started from Mac OS X 10.3.9. If you're using an earlier version of Mac OS X 10.3, download and install Mac OS X 10.3.9.
