Can anyone explain this graph for me please,it dosnt look healthy but im nooo expert.Thanks.

It could be a spot of dust in the disc surface that caused that drop in the graph. Check if the disc is dirty or scratched, and run again the test after cleaning the disc.

That is happened some times with not so reliable disc brand or even with name brand of disc, It all depends to the quality of disc.
