I am a curious person who always likes to learn more. I like solving puzzles and I like working with computers. Which means I enjoy some of the more complex questions on this site, as well as the answers which go into details and explain all facets.

comment Format partition to what block size for photos only
Not quite. I am saying that you can format a filesystem on a partition to use a large blocksize, and that that might be a bit faster. But you can not format the (raw) sectors on the disk. And the fdisk listing is about those sectors.

comment Format partition to what block size for photos only
Old tests on windows (should be more or less the same for Ubuntu) showed that larger cluster sizes (filesystem block size on Ubuntu) speeds up large serial reads. it also has downsized such as wasting space.

fdisk returns the physical sector size that the disk reports. Not the filesystem block size.

comment blocking all outgoing ports and its consequences
Without knowing what you want to do on that server it might be relative harmless. But closing everything including your own access to the server is a traditional mistake. A rather educative one. Whatever you do, make sure you configure things so you can get back in, either via some other way, or via a script which undos things unless cancelled. (e.g. script undo in 10 minutes & Test changes, if it works: great. If not wait 10 minutes until access is restored)

ALL outgoing ports? Including the one you are using to reach the server?

comment Why can't I use a partition?
Why can't you "copy create" (copy or create?) files. Any errors? A sudden lack of desire to do so?

comment Convert running system to RAID 5
RAID 5 needs a minimum of 3 disks, but mdadm --create --level=5 missing /dev/sdb1 /dev/sdc1 might just work.

comment Why could not I export variables permanently?
If you define variables in ~/.profile or ~/.bashrc (or whatever shell you are using. It is not always bash) then you set those only for yourself. They only get executed when you log in. (and only after you log in, if you changed those and did not logout and back in then they will not yet have taken effect). The same holds for /etc/profile, though that will affect all users. -- However what I am missing is your goal. Did you just choose a random example (country), or do you want to set a locale?

comment Creating a FTP server on ubuntu desktop
Regular FTP or sFTP? (Regular ancient FTP uses plain text passwords - Not recommended).
