Second Hard Drive Problems

EDIT: Problem Solved. Apparently when I was using windows I turned on Fast Startup and Hibernation, I installed Windows again and turned them off and reinstall Ubuntu. Now I can write to Second Drive. Thank you everybody.

I was using windows and yesterday I installed Ubuntu 20.04.2 LTS with burned USB, I erased the SSD completely and installed Ubuntu onto this drive. I also have HDD for storage. Everything is working fine. Only problem is I can not make a file or copy file from HDD now. I tried it in terminal but it said the HDD was read-only. Did I make a mistake when installing? Or is it something normal? I just found out this is the case with my SSD drive too (which Ubuntu is running) For more information: I use MSI GF63 Laptop and I have this 3 File Systems shown in my System Monitor application:

1) Device `/dev/nvme0n1p1` Directory `/boot/efi` Type `vfat` Total 535 MB 
2) Device `/dev/nvme0n1p2` Directory `/` Type `ext4` Total 125 GB 
3) Device `/dev/sda2` Directory `/media/myname/drivename` Type `fuseblk` Total 1TB 

I think 2 and 3 are my C(SSD) and D(HDD). I don't know if any of my drives is mounted. Please you can ask any information if you need, I don't know much about what to provide here now. I'd appreciate it if anyone could help

When I write mount -o rw, remount/dev/sda2/media/myname/drivename, this is the result:

Edit: The output of sudo fdisk -l /dev/sda2 is:

Before I get to your main question it might be useful to know that actually both the 1) and 2) partitions are in fact referring to your NVMe drive (nvme0). You can determine this by looking at the device names both refer to nvme0 however one refers to the first partition (p1) and the other to the second partition (p2).

In short, the first partition is a small system partition containing the bootloader for the rest of the operating system which contains among other things the necessary filesystem driver to read the main ext4 filesystem containing the root filesystem.

That bit of trivia aside back to your main question. From what you have said it seems possible that your second hard drive (/dev/sda2) may be mounted as read-only for some reason.

You can use the following command to attempt to fix this, be sure to replace /media/myname/drivename with the actual path:

mount -o rw,remount /dev/sda2 /media/myname/drivename

If that does not work then we may need more information to try and diagnose your problem further if you can add the output of the following command to your question it may help:

cat /proc/mounts

This should help us to determine if any other mount options are causing the issue somehow.

Edit: The reason that your mount command is not working is that you made a few typing mistakes with your spaces. The spacing is required as they are separate arguments and the spaces tell mount where each argument begins and ends. I recommend trying the command again but take care to copy the spaces exactly as in the following example or you can simply try copying and pasting this one.

mount -o rw,remount /dev/sda2 /media/shamsiddin/Shamsiddin

That should do it although I did also forget to mention that if you get a permission denied error when you run the command you may need to run the command using sudo as follows:

sudo mount -o rw,remount /dev/sda2 /media/shamsiddin/Shamsiddin

Hopefully, that will resolve your problem but if it doesn't then the resulting error message should be enlightening at least. Let us know how you get on and if the problem isn't solved please be sure to copy any error messages you get and add them to your question.

Open Disks and look to confirm the details about the drive (and whether it's mounted)

In terminal:

sudo chown myname:myname /media/myname/drivename

You can add a line to /etc/fstab if its not being mounted automatically using the UUID such as (using my example)

UUID=6f71cdf1-61c9-404c-9535-a917b6febf7b /media/graham/STORAGE ext4 defaults 0 0
