The CAM driver does not have this information on hand, and relies on the user to specify a proper density. Ken and I are looking at the best way to deal with these kinds of issues without bloating the driver too much. In the mean time, can you experiment with different densities (via mt) and see if this helps your situation? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
