Disclaimer: I am very new to Linux (1 week).
I have installed the Valve version of Steam on LMDE6. I have used Disks to automatically mount the NTFS drive I used with Windows (doesn’t hold bootloader, it is just for Steam library storage) at boot ( /media/[username]/Gaming ) and I made it the default library folder in Steam.
Running games works perfectly (actually, performance is surprisingly good), but I cannot install them due to a “disk write error”.
I looked for solutions and found this page, from which I understand that I need to change permissions to the mounting point, but when I do, using chown -R, I get a “Read-only filesystem” error for all files and folders.
I can see no options to fix this in Disks and I tried to edit fstab once, but it messed things up so badly I had to use the USB drive with the portable installer to fix things.
It looks like the ntfs-3g FUSE driver does have write support for NTFS (and just confirmed it when responding to @Drathro@dormi.zone below) NTFS is also, like most Linux filesystems, a journaling filesystem, which means that power loss on a mounted filesystem isn’t going to corrupt the filesystem, whereas FAT is not.
It does look like there has been major improvements since the last time I tried this kind of shenanigans. Which admittedly has been many years, these days I just don’t bother with dual booting so I’m free to just use the native FS wherever needed for the OS I’m using OR I have an intermediary like a SAN or it’s on a VM or something
Still though, using a non-native FS in this manner is always more headaches than it’s worth, the no journaling is a corruption risk true, but so is using a non-native FS just in different ways lol
IMO, the use case for this drive is storing re-downloadable data is perfectly fine for exFAT, worst case it corrupts and you have to redownload games from steam
