[smartmontools-support] Log failed: scsi error unsupported field

[Alex R. <mys...@gm...>]

Hi,
I have a Seagate 5TB disk that was given to me because the original 
owner was having trouble with it and thought it was defective (it 
probably is). It's also listed as a "component" by Seagate so not 
covered under warranty.

Before tossing it, I thought I would run some tests. I ran badblocks 
across the majority of the disk and it completed at least one pass 
without error.

I also ran a smartctl long test and it appeared to complete 
successfully, but doesn't display the normal self-test log report at the 
end.

Here is the results of a "smartctl -a" on the device. Can someone tell 
me the significance of the errors below? I've pasted the results here, 
but also pastebinned them in case this info isn't legible
