Hi All

I am trying to make mirror copy of hard drive, The RedHat 4.0 is
installed on IDE hard drive.

1.  Boot from any LiveCD that has SATA support.
2.  mkdir /old /new
3. Mount old drive in /old .. creating /old/boot /old/usr etc where needed and mount the "old" filesystems into these directories 4. Partition the new drive however you like. Create whatever filesystems you like. Mount them as above, but in /new .. so mount your new root filesystem in /new .. your new /boot in /new/boot ... etc. 5. cd into /old and type (without quotes) "tar cf - * | ( cd /new; tar xfp -)" 6. ls -la /old .. if there are any files that begin with a "." .. copy them to /new with cp.
7.  chroot /new
8. modify your /etc/modprobe.conf to accomodate your new module for your SATA drive. 9. Make a new initrd (keep a copy the old one) if you needed to add anything related to your new module. 10. Update your grub config (including device map) to use the new initrd and to accomodate for any drive changes (i.e. /dev/hda becomes /dev/sda, etc).
11.  Install grub on the new device.
12.  Make any necessary changes to other files .. /etc/fstab etc.
13.  Exit the chroot, umount /old /new
14.  Reboot, removing LiveCD.

Hope this helps.
