Hi again!
For background, my machine has a grand total of 8 separate drives: I have the system drive and 3 dedicated game drives that are all NVME, I've got two SSDs and two HDDs. I've mounted these into directories inside my home directory (probably bad practice, might change in the future) with the general format of ~/slow_storage_1, ~/slow_storage_2, ~/ssd_1, ~/games_1 and so on. I've attached a picture of my ls command output. I've also edited fstab and there's also a picture of that. Also, if it's helpful information, the drives all show as normal on Windows side, and according to Windows at least, are using NFTS file system.
The problem is, many of those mounted locations show as read only: In the ls output you can see directory names highlighted, and those directories show as read only. I have no idea why this is, or how to even begin to fix it.
What I would expect to happen is that all of my drives would show up fully usable on both Windows and Linux side of things.
