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. http://en.wikipedia.org/wiki/S.M.A.R.T.#Known_ATA_S.M.A.R.T._attributes Are you seeing any block "remap" activity? http://en.wikipedia.org/wiki/Hard_disk_drive#Error_handling > > Is this disk usable, or is it still in need of replacing? > http://en.wikipedia.org/wiki/S.M.A.R.T.#Background 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?
