Q:
I use TechTool Deluxe with my Mac for disk maintenance, but now I've upgraded to 10.4 Tiger. Are there any issues I should know about?
 
A:
Do not use the Volume Structure repair function of Tech Tool Deluxe 3.0.3 on Mac OS X 10.4 Tiger volumes. It is not compatible with the file system. If you need to repair a 10.4.x volume, use Disk Utility instead.

A "Failed (Error = -64)" message may appear, and other issues can occur, such as a kernel panic message appearing during start up.

Tech Tool Deluxe 3.0.4 has been released and is compatible with Mac OS X 10.4 Tiger volumes.
