Warning: Do not run DiskWarrior or similar utilities on Mac OS X 10.5  
(Leopard)
DiskWarrior and other tools that modify or rebuild the directory of  
volumes should not be run after installing Mac OS X 10.5 (Leopard)  
until further notice or updates from the developers of these tools.
As part of our special report on preparing for Mac OS X 10.5  
(Leopard) published yesterday we noted that previous major Mac OS X  
releases have made significant disk directory changes that can react  
adversely to the processes used by these applications.
Alsoft, the developer of DiskWarrior, has now released a statement on  
compatibility that is somewhat confusing. It reads:
"[...] until we have a copy of the final build of Leopard, we cannot  
completely comment on Leopard compatibility.
"We will absolutely support Mac OS X 10.5. While we have the early  
builds of Mac OS X 10.5 to test with, Apple does not tell us ahead of  
time what changes or enhancements they plan to make until they  
provide us with the software and documentation. Apple engineering may  
make changes right up to the last few days before the release and we  
wouldn't know about them until after the fact.
"As for your current version of DiskWarrior, you can run the  
application knowing no harm will come to the hard drive or to your  
data. If a newer version of DiskWarrior is required, DiskWarrior will  
simply not allow the replacement of the old directory.
"When DiskWarrior 3 was released 3 1/2 years ago, Mac OS X 10.2  
(Jaguar), was the current version of the operating system. When Mac  
OS X 10.3 (Panther) was released we updated DiskWarrior for  
compatibility at no charge. The same is true for when Mac OS X 10.4  
(Tiger) was released - no charge. Each of these updates was available  
through the process of downloading an updater which helps you burn an  
updated DiskWarrior CD. More information will be posted on the Alsoft  
website, once Leopard is released.
Essentially it looks like Alsoft is claiming:
They can't guarantee compatibility of the current DiskWarrior  
iteration with Leopard
The current version of DiskWarrior won't cause damage to Leopard  
disks because it will simply refuse to perform the process for which  
it is designed.
The update for DiskWarrior that makes it compatible with Leopard will  
be free of charge.
Despite point #2, we highly recommend not running DiskWarrior at all  
after installing Mac OS X 10.5 until further information is  
available. All current indications are that the program will run, and  
rebuild directories on bootable Leopard volumes and could result in  
serious consequences, including an inability to startup from the drive.
