I have two hard drives in my system one SSD for the OS and a HDD for data storage. After a fresh restart I check the reading speed of my HDD via:

sudo hdparm -t /dev/sdb

and I get quite varying results (between 15MB/s and 200MB/s) for it.

After I start a python program which performs calculations on the HDD the speed drops extremely (even after I stop the program).hdparm -t /dev/sdb stops working and is not giving any results back. From then on also copying files on or from the HDD is very slow (or not working).

I am using ubuntu 18.04 LTS and the Drive Settings show me the HDD is mounted by NTFS I don't suspect my python code to be the problem since everything runs fine when I pull the data onto the SSD.

It would be very helpful if you could give me advice how to find the source of the problem here!

    I would check the HDD health! If S.M.A.R.T. option is enabled in the BIOS, you can use the GUI tool Disks to get the info of the HDD health: https://askubuntu.com/q/528072/566421 and https://askubuntu.com/q/38566/566421 – pa4080 Sep 24 '19 at 09:57
  • Thank you for your help! The sort Self-Test runs through without a problem, I will report if the longer version yields a problem. Up to now I suspected no hardware-problem because the reading/writing speed was restored after a restart of the system. – some_name.py Sep 24 '19 at 11:42

I think I figured it out the problem was most likely that the drive was format in NTFS. I formatted it to EXT4 and so far no more problems.
