It's "just worked" under -STABLE since whenever the "da" driver replaced the "sd" one, whenever that was. I'm on 4.0-STABLE now, and do nightly backups to a Fujitsu 640M MO drive. From memory, disklabel or the kernel or the combination of the two aren't happy (or weren't the last time I tried it) to use the "auto" argument. I've always had to give it a disktab entry, and I use one of these: mo640|F640|dangerously dedicated Fuj R640:\ :ty=removable:dt=SCSI:rm=#3600:\ :se#2048:nc#151:nt#64:ns#32:sc#2048:su#309247:\ :pc#309247:oc#0:bc#8192:fc#2048: R640|fdisk sliced Fujitsu R640:\ :ty=removable:dt=SCSI:rm=#3600:\ :se#2048:nc#151:nt#64:ns#32:sc#2048:su#309216:\ :pc#309216:oc#0:bc#8192:fc#2048: Actually, I think that I always fdisk and label a partition manually, and then use the sliced version these days. The dedicated one might not work any more. While I'm rambling about experiences with MO drives, I should mention that I only leave this drive mounted long enough to do the backup. I found that if I left it mounted continuously, then at some random time it would stop talking to the SCSI system (lots of "retry" "media fault" type messages in the logs, and no access through the file system). Sorry for such a vague report, but this hasn't happened for a very long time now. I suspect that it would heat up and not recalibrate properly, but I'm hardly knowledgeable enough to make that sort of determination. -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
