Is my disc bust?

Code:
Self-test execution status:      ( 244) Self-test routine in progress...
                                        40% of test remaining.

That suggests to me you need to wait another hours or so for the test to complete.
 
In the past I have had disks which would abort a self test if the OS was accessing them. I could have sworn this disk did the same. However, it does seem to successfully run in background.
Perhaps you were thinking of a captive test?
I am not sure how useful it is to run it in background. If faults are found they would have to be fixed in maintenance mode anyway.
Why? You can repair sectors manually in normal mode. I suppose whether it's a good idea or not depends on where it is and what it's being used for. The data has gone anyway if the sector's bad, so what have you got to lose?
 
smartctl -t long /dev/sda (in maintenance mode)
Do it in normal mode next time. Then you can use it as normal and not have to worry about the heat. It's really a no-brainer.
it said 234 min - will it tell me when it has finished
No. It stops when it finds an error or when it's complete (in 234 minutes). You have to ask it...
smartctl -a /dev/sda
You can run "smartctl -l selftest /dev/sda" (which produces only the output you are interested in) at any point to see how it is getting on. You don't have to wait the whole 4 hours. You already know that there is no point checking before 2 hours though from your previous test.
 
Do it in normal mode next time. Then you can use it as normal and not have to worry about the heat. It's really a no-brainer.

This was the third go
I had difficulties running this, but for this one I waited long after the 4 hours it said it would take.
