Another server came to my house (again) It's CentOS 5, 32 bit. It has 2x500GB WDC Black. RAID 1. The problem is, the 1st HDD was broke. And when I try to boot from the 2nd HDD, it said: GRUB Hard disk error Code: grub>find /grub/stage1 grub>root (hd0,0) grub>setup (hd0) But still no luck. Any idea? Thanks.
