What this probably means is you have a more serious problem with corruption than Disk Utility can fix; it may not have caused any problems, yet, but if left alone it probably will, sooner or later. You can either reformat the drive before you install (if you've backed up your files), or repair the corruption with a more fully-featured disk repair utility, like Disk Warrior, or Drive 10. Something like this is well worth the expense if you don't make regular backups of important files, and can really be a lifesaver when disaster strikes. BRIAN/bpearce at cloud9.net
