Buffalo provides Data Recovery services. Read about it here.
From their notes about what is included in the update: "Improves compatibility with some external USB hard drives." Anyone try this out yet? Or have you learned your lesson from the last update? :)

I installed it on all of our machines. No problems.
Then again, my Buffalo drive never had any issues anyway. I use the Firewire option, not USB. ;)
