I just did a fresh install of Snow Leopard on my main drive. I then downloaded the new 4.2 version of DiskWarrior which is Snow Leopard compatible. The only other things that I've installed on the fresh OS drive are VMWare Fusion, the Kona 3 drivers, and the OS X.6.1 upgrade. Haven't yet installed any other software suites. I then booted from my external drive and ran DiskWarrior 4.2 and scanned the fresh t TB SL disk, and it says that the directory is 28% out of order. Anyone care to comment on this? Should DW be avoided with SL?
