WFG: In writing it all, the seek motor knocked the dust out of it's way? (what dust?)
How about checking all the smart attributes and seeing if others are elevated.

Are you seeing any block "remap" activity?

You have gotten SMART errors from this drive already, so:
You have to ask yourself, 'Do you feel lucky?', Well do y'a...
And the other question: If this drive up and dies shortly and I knew about the smart errors, will
the data owner complain more or less to me about the drive death later or drive replacement hassle now?
Only YOU (and the data owner) know the risk trade-off levels you have to consider.
