	Ok, done. (Oh, BTW, I was having errors like :

ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=112977771
ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=112977803
ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=112977835


	so thought I'd do this too.... So now I see :

Self-test execution status:      ( 119)       The previous self-test completed having
                                      the read element of the test failed.

			and


SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA
_of_first_error
# 1  Extended offline    Completed: read failure       70%      4934         259
34873

	So is there something I should do?
