Run "smartctl -t long /dev/hdX" for all your drives. After finishing the
self test of one drive run "smartctl -a /dev/hdX" to see if there are
serious errors reported.

If there are real errors: no. But it is normal to have changes in the
stored S.M.A.R.T. data registers of a drive. So messages (this is no
error) like this is normal:
