DiskWarrior 4.2 finds incorrect critical Volume info on 10.6

by civ10 / September 6, 2009 4:46 PM PDT

I have a 2008 iMac 2.4GHz Intel C2D ModelID iMac8,1. I installed 10.6 on two volumes, one 100% clean (no migration) and the second with full migration from my 10.5.8 volume. I repaired the permissions and the disk on each of the two 10.6 volumes with Disk Utility. I installed the new DiskWarrior 4.2 and checked the two 10.6 volumes. On both, DiskWarrior reported "Critical values in the Volume information were incorrect and were repaired". Running DW the second time, it finds everything OK. However, if I boot on on the first 10.6 volume and then boot on the second and check the first volume, DiskWarrior reports again that "Critical values in the Volume information were incorrect and were repaired".
This happens every time I boot on one of the 10.6 volumes and do a DW check of the other.
Is this a real problem on the 10.6 volumes or just a bug in the new DiskWarrior?
Can anybody help me please?

First thoughts would be that DW was the problem

It is very interesting. I just got the 4.2 upgrade but did not use it. Just wonder: what do you call volumes? Are these partitions or different hard drives on the same computer? What happens if you boot from 4.2 CD and then check the drive? I believe this is the recommended way of using DW. And if one does that, it should be possible to check both volumes consecutively with the same boot from CD.

In reply to: important info

Volumes are partitions of hard drives. For instance my iMac internal 500GB HD and my external 1TB My Book Studio Edition HD, each have four partitions of various sizes. The 1st internal partition is my main boot-up volume with 10.6, the 1st external partition is a clone of the main boot-up volume, the 2nd external partition is the Time Machine and the 3rd external partition is a temporary clone of my former 10.5.8 boot-up volume (I'll keep it until the transition to 10.6 is 100%).
I run DiskWarrior 4.2 from the bootable HD volumes, as well as booted from the DW DVD. The result is always the same: DW reports "Critical values in the Volume information were incorrect and were repaired" on the two partition with 10.6, while it finds no problems on the one with 10.5.8.
Regarding the DW usage, If you have just one bootable volume, then DW has to run booted from the DVD. If you have more than one bootable HD volume, it's much faster to reboot and run it from HD.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
