I've had that once.  My problem was heat related and of course
the drive worked fine when I took it out for testing.  
In my case there were (mysterious) errors in both 
/var/log/messages and /var/log/warn

As to re-inserting it into the array, yes you can do that.
In my case I found it much faster to nuke the drive
and let it rebuild the array on a fresh drive than to 
let it try to repair an out of date image.
