Hi all, I have raided the 2 SCSI drives on a DELL PE1550 with RAID 1 including the /boot partition. I found that one of the drive can't boot, how do I make both drives bootable so that I have a true mirror? I've tried to dd the first few sectors on the drive that boots to the other drive unseccessfully using dd if=/dev/sda bs=512 count=[1,2,3], grub starts then hang. Can someone please help ? Many thanks, Yang
