I apologize for re-opening this somewhat old thread, but I'm having a similar issue and not getting the results you described. I performed the SMART short test, and received the following:
# 1 Short offline Completed: read failure 90% 10769 980534200
# 2 Short offline Completed: read failure 90% 10769 980534202
I did:
980534200 / 8 = 980534200
sudo dd if=/dev/zero of=/dev/sda conv=sync bs=4096 count=1 seek=980534200
sudo sync
That caused me to get another bad sector upon running the self test:
# 1 Short offline Completed: read failure 90% 10769 991816368
# 2 Short offline Completed: read failure 90% 10769 980534200
# 3 Short offline Completed: read failure 90% 10769 980534202
I then repeated, as you instructed, and now have the following:
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Short offline Completed: read failure 90% 10769 3885852504
# 2 Short offline Completed: read failure 90% 10769 991816368
# 3 Short offline Completed: read failure 90% 10769 980534200
# 4 Short offline Completed: read failure 90% 10769 980534202
