My questions are these:
Can I plug both the old drive and new drive into another computer, and use dd to copy the old drives partition/data to the new one, and then plug the new one into the server? I know I'd have to follow the re-adding a drive to greyhole wiki guide (and/or the adding a hard drive to the storage pool wiki guide also).
Should I just plug the new drive into the server, and let greyhole do it's thing? (This is instead of doing the first option, or if the old drive won't allow me to read from it).
Thanks, and have a great day.

Patrick.
