Hi Reindl,

My comments are interleaved. thanks:

Here I run the command sfdisk -d /dev/$GOOD_DISK | sfdisk -f /dev/$BAD_DISK.

I think dd and sfdisk are doing the same thing which is cloning the
partitions and copy the MBR ?

># force OS to read partition tables
>partprobe $BAD_DISK

Why run partprobe if the partitions have not changed?


># install bootloader on replacement disk grub2-install "$BAD_DISK"

Here don't you mean grub-install not grub2-install?
