OT: DiskWarrior vs. Repair Permissions
on Nov 14, 2009 at 10:28:15 pm

I've used DW for years and have also used Repair Permissions (after trashing prefs). I sort of knew that both DW and Repair Permissions both affected the disk's directory, but I didn't know if the order of using DW & RP mattered. I contacted support at DW and they replied, "You always want to rebuild the directory first (with DW). Then, repair permissions. Since repairing permissions changes information in the directory, you want the directory to be in a pristine condition first."

Appreciate your sharing the feedback from Alsoft, John... you never know when someone might be asking themselves a similar question.

That said, I'm guessing its just the original subject line, but in case anyone else wanders along later and finds themselves confused because of it ... Disk Warrior and Repair Permissions are totally different operations; Repair Permissions compares the permissions of a subset of files (the basic OS instal) within your existing directory and if it finds any permissions that are not set according to their predetermined state then it changes them back, Disk Warrior on the other hand builds/rebuilds an entirely new directory to completely replace the old one, not a permissions check but a brand new directory, thereby fixing many possible corruption issues beyond mere permissions bits.

Best
Andy

Thanks for the further clarification, Andy. That's good to know.

I guess must be a kind of accumulative errors. Some times is necessary to run it few times till the graphic is clean.
You fully clean them or go just with one pass?
