Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

I know about the how to -
http://smartmontools.sourceforge.net/badblockhowto.html

But how can I get the LBA?
And is there some diagnostic tool for WD in ports?
