What Dan said...the purpose of DiskWarrior is to get your system back up to the point you can recover your data. Get it off, nuke & pave. Keep a close eye on the drive, as well... 'soft' errors like directory corruption, etc are often portents of impending HDD hardware failure. In normal day to day use OSX should NOT REQUIRE disk repair or directory repair. If this happens, it should be a wake up call that something is seriously wrong, and you should be prepared to replace the hardware and restore known-good backups at any time. OSX does NOT NEED 'routine maintenance' with ANY sort of utility, other than using Onyx or some other such utility to do the scheduled log rotation scripts...and even there OS X now manages those much more rationally than it used to, in 10.6 (and possibly 10.5) they'll run at the next time the computer is started if it's off when they normally run. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: TechTool Deluxe Froze on Restart
I wouldn't think of "Disk Utility" as liar, liar, liar just that it has done the best that it is able to do, and the drive "should" work know. As I mentioned before, Disk Warrior and TTP and just able to do more and resolve more problems. cjc PS I hope this discussion is actually helping people and we aren't just rambling?

Re: TechTool Deluxe Froze on Restart
To the best of my knowledge, Disk Warrior is able to do a bit more to try and repair the disk. Whereas "Repair Disk" is fairly minimal. For Windows users, think of Repair Disk as CHKDSK and DW as Norton Disk Doctor.
