I am thinking that how I went about this might help you solidify things, so far there have been some very terrific suggestions on partitioning.TJ_Vinny wrote: ↑Mon Jul 30, 2018 2:16 pm
I forgot to mention, the SSD is 120 GB and LM is already installed. The entire HDD is still unallocated, fresh out of the box.
As I didn't get far into it at all, I was planning on wiping the SSD through the live session and starting over.
[EDIT] So, the plan for this build is to be a work station for art, music, 3d rendering and animation. I have plans for only using software like: Gimp, Audacity, Krita, Blender, Wings3D, Firefox, the Libre Office Suite,possibly Scribus and probably a couple of others. It would be nice to know how much of these applications would be spread out throughout the system, but if the OS needs around 40gb, then I guess it wouldn't matter much with a 120GB SSD.
I used the ISO Gparted in advance of the install to set up these partitions. Then used "Something Else" to assign the / and /home and /swap functions..... you will note that this is an SSD and I left almost half of it "unused" initially. For you, liken that
sda4 /backuppartition to your HDD. When I did the installs, I had install ignore sda4 as "unused"..... the same will go for your HDD. Again, with the first install of 18.3 Cinnamon in Something Else, I left sda4 as unallocated and unformatted. it did not get formatted until after 18.3 Cinnamon was up and running.
My laptop has 500gB SSD and 12gB RAM, and no room for anything else, not even an optical DVD.
I use an extUSB HDD for backups of the alternate OS that is on sda6 ( that OS changes with my moods )
The extUSB HDD is also used for /home backups from time to time.
Note that my initial partition setup allowed way too much room for the OS of Linux, 3 times for 18.3 Cinnamon.
I recognized that and shrunk sda6 down to 20gB and that ended up 4x too much for Xcfe.
But, at first, I installed LM19 on sda6 to play with.... so, it is what it turned out to be.
One last comment: as I have 12gB of RAM, there is no need for /swap so that partition is only 14Mbytes
So, you need to consider how much RAM you will have, and how big those special programs are going to hit the RAM ( video editing )
