Adaptec 1742 is supported, though it took a long enough time to find its way into CAM. Same for the NCR 810. For certain applications, also, you _want_ to turn off the automatic bad sector sparing: it's incompatible with spindle sync, for example, where you want to spare all drives or none, so that the spindles don't desyncronize on a sparing hit for one drive, but not another. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
