Google: seagate disk firmware
Brings you to a page to enter your SN to check, but both of those SNs
return: no firmware found for this SN

I would change the copy method from `dd` to something a little higher level
like `dump`/`restore` or maybe create the file systems on the destination
disk and `rsync`.

Hope either of those options work.
