Really slow on external HDD setup [SOLVED]

Hi there!

Whenever I go through external HDD setup or Backup options related to HDD gui just freeze for a minute or two. After that it goes well.
I’ve seen that it tries to connect to FTP on 192.168.0.100 even though my IP is different and I didn’t install FTP server yet. Could it be the cause?
HW: Raspberry Pi 3, SD card + USB-HDD.

Thanks for the great image! It is so useful.

BTW, do I get hdparm installed by default or not?

Fixed with the correct IP address for FTP in config file.
