[X4U] Disk Utility on Panther and Tiger

[Wayne Clodfelter]

I have a Panther boot volume and a Tiger boot volume.
I started up in Panther and was going to open Disk Utility to verify  
the Tiger disk.
Oops! What if DU on Panther is not compatible with Tiger?
It probably isn't--though I have not seen a statement to that effect  
anywhere.

Two thoughts here.
ONE, Disk Utility under a superseded version of OS X should not even  
be able to verify/repair a system disk of a later release unless it  
is compatible. Does anyone know if it attempts the verify/repair of  
if it balks when such a run is attempted?

TWO, it should be possible for the latest version of Disk Utility to  
be installed/copied over to boot volumes containing earlier OS X  
releases.
Has anyone done this and achieved a working application? How did you  
achieve the install/copy?
Of course, this raises the question whether the latest release of  
Disk Utility is always backwards compatible with earlier OS X  
incarnations. Is this true or not?
