I'd only be worried if there is stuff on there you don't want to lose. 
But as you aren't running any redundancy (You mustn't really be worried 
about losing stuff on there) then I wouldn't worry about a few checksum 

Make sure you have decent backups.

It could be disk, controller, RAM, drivers, PSU, etc. So hard to tell.

If there is data loss it will tell you and list the errors.
