OSX drive setting with HD SpeedTools


In my previous OSX install (see my thread "Booting OSX from OS9"), my drive had been set (long before OSX install) with HD SpeedTools and I could'nt switch from OS9 to OSX.

I had to reformat my ATA 16 Gb drive with Apple Drive Setup and reinstalled OSX and OS9 on HFS+ separate partitions.
Everything seems right now I can switch from OS9 to OSX.

Conclusion : OSX is not recognised when installed on a partition driven by a third-party tool.
