Yes! 'dd' does work. Scrutiniser's 'bs=1M' did the job. A bootable clone in 2.75hours with results returned with no discrepancies.
For your goal IMHO it's better (and easier) to use dd_rescue than dd, even better to use ddrescue. And you learn to use something useful in case of hardware problems (dead sectors). For some more info: System Administration Bits of Knowledge
To install and learn dd_rescue in Ubuntu:
Yes, dd_rescue is in package ddrescue (Debian and Ubuntu).
To install and learn ddrescue in Ubuntu:
Yes, ddrescue is in package gddrescue (Debian and Ubuntu).
For single partitions, best (and often much faster) is to use Partimage.

I am using ufsdump and ufsrestore to clone the root disk on one of my servers. I would like to automate this as much as possible, but have run into a problem where it prompts for changing the owner/mode when it is complete.
Any ideas for running this in the background and not being prompted?

HD(4) Linux Programmer's Manual HD(4)NAME
hd - MFM/IDE hard disk devices
DESCRIPTION
The hd* devices are block devices to access MFM/IDE hard disk drives in raw mode. The master drive on the primary IDE controller (major
device number 3) is hda; the slave drive is hdb. The master drive of the second controller (major device number 22) is hdc and the slave
hdd.
General IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
partition on that physical drive. The first form, hdX, is used to address the whole drive. Partition numbers are assigned in the order
the partitions are discovered, and only non-empty, non-extended partitions get a number. However, partition numbers 1-4 are given to the
four partitions described in the MBR (the `primary' partitions), regardless of whether they are unused or extended. Thus, the first logi-
cal partition will be hdX5. Both DOS-type partitioning and BSD-disklabel partitioning are supported. You can have at most 63 partitions
on an IDE disk.
For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS `primary' partition on the
second one.
They are typically created by:
mknod -m 660 /dev/hda b 3 0
mknod -m 660 /dev/hda1 b 3 1
mknod -m 660 /dev/hda2 b 3 2
...
mknod -m 660 /dev/hda8 b 3 8
mknod -m 660 /dev/hdb b 3 64
mknod -m 660 /dev/hdb1 b 3 65
mknod -m 660 /dev/hdb2 b 3 66
...
mknod -m 660 /dev/hdb8 b 3 72
