maybe a bit offtopic but:
I use HDToolBox from OS3.9 to set up partitions or major changes for them, works all the time. I also use HDToolBox from WB3.1 (if i'm booted to 3.1) for certain minor changes that don't involve partition size changes. I can avoid using these tools for renaming partitions (Relabel) or changing boot priorities (ChangeBootPri - thanks Thomas
). HDInstTools has gave me problems in the past, saving wrong partition info. Won't be using it.
It would be nice to have a HDToolBox version which has all the fixes of the 3.9 version and still it would work on WB 3.0 or even lower versions.
