What are you trying for? Your own data recovery or fast possibly bad data, e.g., video data off a raw partition? For fast bad data you want to set the RC (read continuous) bit. For roll-your-own recovery you want to clear AWRE and ARRE and clear TB (transfer block). > Oh, and how do I do it in CAM? I'm running -current of January 24 > vintage. Thanks. :) Last I heard the -v mode page editor was up and running. Peter -- Peter Dufault (dufault@hda.com) Realtime development, Machine control, HD Associates, Inc.
