OK, now go back to the main screen in Macrium and
see what the disk ID looks like in the picture.

Each prospective disk to be backed up, shows a Disk ID
in the GUI where you operate those tick boxes.

See if it matches "5A032C0C" hex.

You can edit the XML file, and change the
instances of 5A032C0C to match what the current
drive value is. Then save. The numbers are hex,
so valid values are 0123456789ABCDEF and not any
other characters.

I'm only suggesting this, to make the error go away.
I think your backups are likely to be OK. You can
double click an MRIMG file and have a look at it
for restoration purposes, to see if it matches
your setup or not. The Disk ID on the backup probably
does match the Disk ID of the disk it's going back onto.
