If you have X running, you can start palimpset and view SMART data. If
you don't have X running, you can run "devkit-disks --dump" to view
SMART data. Look for "reallocated sectors", "uncorrectable sectors", or
"pending sectors", and if they are not showing 0 for current value, then
you have bad sectors forming.
The OP already said he didn't have any drive errors...

I also have the same problem -- my RAID-1 array regularly has a non-zero mismatch_cnt. For a RAID-1 array, this isn't *necessarily* a problem, especially with swap or mmap'ed files on the array. See this post on the CentOS mailing list for more info:
