Display Environment: Cinnamon
I have three 1 TB HDDs, one has Windows 10, one has my personal files and the third one I added recently to install Linux Mint.
I'm not a tech savvy person; I just wanted to try using Linux because Windows 10 has Internet connection problems for which I tried every solution possible (including deleting everything and reinstalling Windows) without success.
I went through the essential things that I should set up after the installation with the help of this post.
As recommended by that post, I wanted to create a partition to store snapshots:
First I went to 'Disk', looked at the disk where Linux was installed and it showed that I had:"Preferably configure Timeshift to put its snapshots on a separate dedicated hard disk partition (20 GB is a workable and reasonable minimum size for that partition), so it won't eat disk space needed by your system."
Partition 1: FAT32(Bootable) 537 MB (0.2% full)
Partition 2: Extended, 1000 GB
Partition 5: Ext4, Linux, 1000 GB (3.4% full)
I felt a bit confused because it's a 1 TB HDD, so why do both Partition 2 and Partition 5 have 1 TB storage available?
I searched information about Linux partitions to understand this better and found this post, where I used 'sudo fdisk -l' to see what partitioning standard was being used. I got the following warnings (I assume they are warnings because the text was red):
"Partition 2 does not start on physical sector boundary."
^This was below the information about the disk where Linux was installed
I found this thread, and it seems this can be fixed with GParted.
I installed it, and just looked at what the disk with linux looks like:"use Gparted to move the partition so that it starts at 4096-byte sector; setting the start boundary at 1 MiB is an easy way to do it."
/dev/sdb1: fat, /boot/efi, 512 MiB (1.04 MiB used)
▼/deb/sdb2: extended 931.01 GiB
/deb/sdb5: ext4, /,/run/tim..., 931.01 GiB (31.58 GiB used)
To sum this up:
1. Is is normal for the partitions to look like that? Will the misalignment be a problem?
2. If it's not a problem, then, how do I created the partition?
I was thinking of using this article as a guide to do it, but there, it shows a unallocated partition which is deleted to, i guess, make space for the new, smaller partition. There isn't anything like that in my Linux Mint HDD.
I have searched all of these things (about extended partitions, about how to create a new one, about the "Partition does not start on physical sector boundary.", etc), but it seems that other people's situations are different from mine (many threads are about creating a new 'home', 'swap', or 'boot' partition, which is not what I want to do), so I don't know what to do.
