I've used it under 2.1R, and I'm now using it under 2.2-snap-960801. The block write performance (~3.3MB/s) isn't as good as I thought it would be, but it's good enough.

The Grand Prix must be really noisy, as my Atlas has a constant ear-annoying whine (I think I'm going to go deaf in my right ear, listening to it ;-(), and perhaps makes the loudest seek noises that I've ever heard. -- Darryl Okahata Internet: darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
