I've replaced a failed disk in my raid 1 setup. I replaced the disk (hda 
on-board ide), however the system then hung on reboot, this was because 
hda, being blank, had no MBR. The second disk (hde) is plugged into a 
promise ide card. So I went into the bios and set it to boot off the 
promise card first. Reboot when fine. I partitioned the new disk and 
added it to the array.
    
I would check that this really worked.

What do you have in "fdisk -l" and "cat /proc/mdstat".

I'm pretty sure it did. Attached are the outputs from fdisk and mdstat.

This doesn't look like a partition table
