Ian, It would also help if you posted the details of your setup using: cat /proc/partitions cat /proc/mdstat mdadm -D /dev/md# - for each of the devices above. mdadm -E /dev/sd<drive><#> - for each disk or partition in the array from above. But the suggestions to ddrescue the going bad drive onto a new disk is a good one. On my debian system, I would do the following: sudo apt-get install gddrescue ddrescue /dev/sde /dev/sdf /var/tmp/ddrecue-sde.log and see how that goes.
