I'm going to copy it onto a fresh drive. (Details below, if it's relevant.) Using 2 ATA/66 drives, this has proven to be very, very SLOW. So I'm left with a hardware question: Which is faster: a) Leave both drives on the same cable, set one as master and the other as slave b) Put each drive on its own cable, set them both as master c) No difference d) Depends on your mainboard Here is my 'cloning' process - perhaps this is just a slow operation: I've prepared my new drive with fdisk, disklabel and newfs. To perform the 'clone' I'm mounting the new filesystem on /mnt, and piping dump into restore like this: cd /mnt dump -0uaf - /dev/ad0s1a | restore -rf - -- Christopher Farley www.northernbrewer.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
