I need having two same hard disks (included
o.s.):
mounted on primary channel as Master and the
other
mounted on secondary channel as Master.
I want to boot always system from primary disk.
I want to reserve secondary master disk
in destruction eventuality ,
so I can substitute it on primary master
channel.
OS : only Linux Red Hat 7.3
Boot Loader: GRUB
IDE1: prim. master HD: 19
GB disk "hda"
IDE: sec. master HD:
30 GB disk "hdc"
I tried to copy all disk from "hda" into "hdc", with Norton Ghost 5.
Copy failed at about 80% and system reset !
So I copied with "dd" command from Linux,
MBR (first 512 Bytes) and all partitions of my hda into hdb.
I modified with fdisk partition table in "hdc" because it's different size
in front of hda.
When I put disk "hdc" on IDE1 as master and unplugged hda
system doesn' t start with a message GRUB !!!
Also Norton ghost i have the same problem copying partion to
partition.
I supposed that there is something into boot loader which referencing
to
particular disk ?!!
I don't understand why a phisical disk copy doesn't
boot !!!!
