It is most likely that the drive is dying.

Well, it's not completely dead yet. The error has to get to
the md driver before the disk fails. Although the message says
"UncorrectableError", Linux will in fact retry it a while before
reporting the error to md. If it eventually succeeds, the drive is not
marked failed.
