[QUOTE="Randy B. Singer, post: 1179476, member: 190607"] It used to be that you were warned against repairing permissions on one disk while booted from another because only the receipt files on the drive you were booted from would be consulted, not the receipt files on the drive you were repairing, and thus not all permissions would be set correctly. Though it hasn't been documented by Apple, this is no longer necessary. As of late in OS X 10.2, you can run Repair Permissions while booted from a disk other than the one that you are repairing (i.e. the OS X installer disk), and it will correctly use the receipts on the disk being repaired. See: [url=http://www.macattorney.com/ts.html]OS X Maintenance And Troubleshooting[/url] Item #1, Maintenance Myth #1 As for running Disk Utility/Repair Disk, yes, Apple recommends doing that over running FSCK. However, you can't run DU/RD if you don't have the original disks, which is what I was talking about. FSCK isn't deprecated, it's just that DU/RD is preferred. Also note that doing a Safe Boot is what Apple recommends doing *first* in this article: [url=http://support.apple.com/kb/TS1417]Resolve startup issues and perform disk maintenance with Disk Utility and fsck[/url] ___________________________________________ Randy B.
