Hmm, if kscd is polling the drive once a second, and you have both disk and CDROM on the primary, I'd bet those blinking lights are from accesses to the CDROM and not the disk... However in you probemessages above disk and CDROM are located on seperate controllers, so now what gives ? -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
