You have another problem too. Your using Samsung magician software. I'm not saying it isnt' accurate. But try using AS SSD. It's what I use. The 840 pro should get a score of over 1000. You can also use Crystal Disk Mark or Anvil Storage Utility
Do you have enough space on the drive used for overprovisioning? You can do that in the magician software. It's suppose to help performance. I doubt this is your problem though.
Another problem is I can't under stand your question under the picture. Are you not familiar with the English language? What does "write not found ssd hard disk" mean?
