Cybernetnews.com just had a makeover, and I was checking it out when I saw this post from yesterday

Driver Manager: Hide Drives, Assign Drive Letters to Folders, and More

Looks like a really good program, and best of all it's free.
I'm about to download and play with now. For one it has a benchmark tool for drives I want to check out. But looks like it could come in very handy.

This free app will surely be a gem for any information-bearing geek out there.
