Info regarding Diswarrior 4 and Leopard compatibility

Question

I emailed Alsoft regarding Diskwarrior 4 and Leopard compatibility. Here is the response I got.
+DiskWarrior 4.0 will successfully rebuild a disk that has Mac OS X 10.5+
+Leopard installed or a disk that has been attached to a computer running+
Leopard.
+However, some operating system functionality has changed within Leopard+
+itself. As such, there are some compatibility issues when running an+
+installed copy of DiskWarrior 4.0 while started up from Mac OS X 10.5+
+Leopard. Alsoft currently recommends that you do not run DiskWarrior 4.0+
+while the computer is started from Mac OS X 10.5 Leopard.+
+Instead, to run DiskWarrior, you should start up the computer from either:+
+1) A DiskWarrior 4.0 CD.+
+2) Any disk that starts up in 10.4.x and then run DiskWarrior 4.0.+
+An updated version of DiskWarrior that has complete Leopard+
+compatibility will be released soon as a free download for existing+
+owners of DiskWarrior 4.0.+
+-- What you can expect when running DiskWarrior 4.0 under Mac OS X+
+10.4.x and rebuilding a Leopard disk.+
+All features work as expected with one exception: FileVaults created+
+while started from Leopard are not visible to DiskWarrior 4.0 and cannot+
+be rebuilt (repaired).+
+-- What you can expect when running DiskWarrior 4.0 under Mac OS X 10.5+
+and rebuilding a Leopard disk.+
+While not recommended (and discouraged), if you do run DiskWarrior 4.0+
+while started from Mac OS X 10.5 you might encounter some problems such as:+
+1) There is a lengthy delay whenever DiskWarrior is determining which+
+drives are currently attached. This delay is dependent upon the number+
+of attached drives and may last up to 2 or 3 minutes. You will+
+experience this delay when first starting DiskWarrior, whenever a disk+
+is attached or detached while DiskWarrior is running but idle, and+
+whenever a rebuild is completed or canceled.+
+2) You cannot rebuild FileVaults or disk images.+
+3) In step 9 (comparing directories) of a rebuild, the progress bar+
+might get to 100% even though the comparison step is not finished.+
+4) When performing Check All Files and Folders the progress bar might+
+get to 100% even though the check is not finished.+
+5) After rebuilding a disk, DiskWarrior may report that some files or+
+folders have had their permissions changed. This is inaccurate and the+
+permissions have not been changed.+
+To repeat, an updated version of DiskWarrior that has complete Leopard+
+compatibility will be released soon as a free download for existing+
+owners of DiskWarrior 4.0.+
+-- What about DiskWarrior 3?+
+DiskWarrior 3 and earlier versions are not compatible with Mac OS X 10.5+
+(Leopard). Alsoft does not recommend running DiskWarrior 3 or earlier on+
+a disk that has Mac OS X 10.5 Leopard installed or a disk that has been+
+attached to a computer running Leopard.+

So, it seems it will work but you need to run it from the disk or if you have it installed on a external drive running Tiger, it will work.

Answer 1

If you open your Tiger Address Book, select all cards, drag them to the desktop, it will make one big "mega-VCF" card with a name like "Alan Adams and 543 others.vcf" Dump that to a flash drive or email it to yourself, then doubleclick on it on the Leopard machine. They will all import just fine into your Leopard Address Book.
Try doing something similar with your iCal data, Open the application, choose your calendars one at a time, and select File > Export. That should make a big "mega-ics" calendar card with a name like "work.ics" or "home.ics, i.e., "originalcalendarname.ics" with all the events of that calendar. Then same drill: dump that to a flash drive or email it to yourself, then doubleclick on it on the Leopard machine.
Both generation methods create text files, which should import just fine into the Leopard applications.
