I have a friend who's computer is not booting up properly using OS 9.

Can DiskWarrior 3 [OS X version] be used to repair an HFS+ OS 9 disk?

Any help would be great .

thanks

Yes (It has both OS X and OS 9 versions on it )

But you don't need to run the OS 9 version to fix OS 9 disks -- because an HFS+ disk is an HFS+ disk, no matter what OS is on it. (Later versions of OS X have needed updated DiskWarrior not because of the OS installed, but because of newer versions of HFS+.)

is techtool pro the same way? (can it check HFS+ OS 9 disks using the latest disk)?

also, which one should I run first?

thanks for the help
