Questions[fujitsu-siemens](ubuntu)

I just installed my first Ubuntu Server on some old server hardware, a Fujitsu Primergy TX200 S6.

I want to make a NAS solution with this and maybe install plex in the future or something else.

My question now is: I have two 2TB disk and four 4TB disk installed in it but when I do

sudo lshw -class disk -short

it shows me all my disks but it looks like the 4TB disk only use 2TB each.

Did I miss something? Does Ubuntu server support 4TB disks ? Does my hardware support 4TB disks? I looked at the specs and did not find anything that said it did not support.

I recently upgraded to Ubuntu 20.04. After reboot audio is not working. I tried to reinstall pulseaudio and alsa but still not working:

sudo apt-get install --reinstall alsa-base pulseaudio 
sudo alsa force-reload

Still not working.

I've installed Ubuntu 16.04 LTS on a FS Esprimo V5555 notebook and I cannot see a very big part of the screen. (like I open system settings and the bottom half of it is out of the screen, I can't drag and drop and I can't scroll it) I only have 640x480 resolution in the settings (my notebook can do 1280x800, it has Sis Mirage 3). Same happened in 14.04 LTS. What could be a working solution?
