I use dd to copy entire drives and partitions (it's my backup scheme). Since it works at both the /dev/hda and /dev/hdaX levels, I think it might. If there's a lot of angst about trying it, you might do this experiment: dd if=/dev/hda of=/dev/null bs=512 It won't prove the whole thing will work, but if it emits errors, it might prove it won't before you go on to try it. I do it this way: date; dd if=/dev/hda of=/dev/null bs=512; date 'cause I'm interested in how long it takes... If you've got the new single drive, you could just try it. The worst likely is you'd need to re-do the new drive. I assume the new drive is big enough? I'd like to know the outcome if you'd post it to the group.
