+if you have a spare PSU, you could just put that psu on that disk alone, and 
+hotwire the header plug to start the psu voltages, to pre-power your disk 
+only.
+
+then proceed and see if that's really the issue.
+
+other ideas: 
+1) the onboard fakeraid is getting initialized and has an effect on it (check 
+bios after plugging disks in)
+2) the 7th and 8th port alone is a different chipset and has some weird issues, 
+like when 8th port is plugged, 7th starts failing
+3) i guess software is always possible, but i would start eliminating all the 
+hardware issues
+
+btw: what happens if you add the 3TB once more? will the reallocated sectors 
+show up again? (i wonder)
+
+if all this fails, i'd send an email to lkml to get more ideas or ways to 
+check it.
