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". --Mike Bird I'm pretty sure it did. Attached are the outputs from fdisk and mdstat. regards, drbob

This doesn't look like a partition table
