Firstly, i have a problem with hard disk (partition dissapearing while copying) after this i installed the SATA/AHCI intel chipset drivers. Now it's fine but copy speed is very low.
Look this video: first part from Seagate HDD to a SSD then from Seagate HDD folder to other folder on same HDD.

And here is a screenshot from HD Tune: https://i.gyazo.com/cc0acd8281715ffb...5783e0bedf.png
I've tryed chkdsk and resolved something but nothing changed. I've tried today defrag with a special software and says 20hours remaining after 3 hours.
What is wrong?
