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.


All seems fine, but this part is interesting:

# 6  Short captive       Completed without error       00%     55438         -


So, this HDD has 400 or 55439 power-on hours?

Thanks in advance!
