Problem installing games from Steam on a secondary SSD

[honest knoll]

Greetings to all ^^
I installed Linux Mint Cinnamon 22.1 ‘Xia’ last night and noticed a small problem: I can't install Steam games on my secondary SSD...
I think this drive is in read-only mode.
Do you think that's the case? If so, can you help me, please? If you think it's something else, could you tell me what I need to do?
Thank you in advance and have a great morning ^^

PS: This Linux is the only operating system on this computer.

Hi! Please launch Disk and check if the secondary SSD is mounted. Moreover, it must be in ext4 file format

Hello, I just checked, and this secondary SSD is properly mounted.
Where can I see the file format?
Sorry, this is my first time using Linux.

Ah Nice. You can launch the application Disks ... click on the secondary drive. Its in contents section

[honest knoll]

Is it in the options?

[fading granite]

you mean Disks? to my knowledge this is installed by default in Mint

its looks like this

Ah ! I am so sorry, English is not my native language, so my interface is not in this language...

No worries

Contents NTFS — Mounted on /mnt/SSD_Jeux

i see ... unfortunately, you need to reformat that to ext4, but be careful if you have important files in that SSD card because it will be deleted

[honest knoll]

No worries (this disc is empty).
How can I do this in Mint?

I figured out how to format
Would you recommend a quick or full format? And with GPT partitioning?

[fading granite]

personally i would go with quick format since you do not need excessively increase the privacy by adding zero to the SSD. However, please be ultra careful of selecting the drive since this is one way process and no turning back. Make sure you are formatting your secondary SSD

Thank you ^^
I just started formatting the correct disk ^^

It works ^^
