Cpanel is not terribly intelligent about interpreting SMART errors or how it runs the SMART monitoring or analysis scripts. As a result is is pretty common to receive Cpanel SMART alerts which are bogus.
Disable smart errors in cPanel is a simple task, login to your server and execute;
touch /var/cpanel/disablesmartcheck
This should now create the file /var/cpanel/disablesmartcheck
Now proceede to updating cPanel to complete the process by executing;
/scripts/upcp –force
This may take a few minutes to fully update cPanel, once complete smart errors will now be disabled
