Let's say you had ad0 and da0 as the two drives. You would simply do "dd if=ad0 of=da0 bs=8096" . This will do an "image copy", making the partitions and everything. The 2nd drive *must* be as large as the first. If it's a little bigger, that's OK , but you'll not use the "extra" part. Also, here's something that will work with any drive, but it's a little tricky. First create 3 directories on the 1st drive's root partition called slash, newvar and newusr. Run /stand/sysinstall with both drives in the machine. Then choose "Custom Installation". Run "Partition", choosing the SCSI drive as the one you want to perform the operations upon. Usually, you want to choose the whole disk, then type "Q" and say "Yes" to the boot manager question. Then run "Label" and choose partitions to match the sizes of your / , /var and /usr partitions on the old drive. Mount them as /slash, /newvar and /newusr . Be sure to also make a swap partition. Then type "W" instead of "Q" to leave the "Label" menu. You will be asked if you want to continue. Say "Yes" and the new drive will be 'fsck'd' and mounted. Exit SysInstall. Now, cd to /slash and do " dump 0 -f - / | restore -r -f - ", cd to /newvar and do " dump 0 -f - /var | restore -r -f - " and then cd to /newusr and do " dump 0 -f - /usr | restore -r -f - " . If it's easier, you can also use "rsync" from ports to copy the partitions. You need something that will create special files correctly. Now, edit /slash/etc/fstab so that the devices are correct, remove the IDE drive, make the SCSI the boot drive and reboot. The first option would be far easier, of course, but the drive sizes need to match, with the SCSI being no smaller. Hope this helps. I may have forgotten something because it's been a while since I did this last.
