Permanent drives should be put wherever you want them to, for example I have mine mounted in /ld1 for Large Disk 1. /media is supposed to be used by systems to mount things you plug, but some systems move that to /var/run/media or other places. /mnt is there so you don't have to create a folder in case you want to mount something really quick.

Mount your internal disks to /D:, /E:, /F:, etc.

Idk, I mount my disks in /mnt/whatever, though I don't think it matters where you mount them.

Anything I add to fstab gets mounted in /mnt and removable drives get auto mounted to /media. Linux doesn't care where you mount your drives, they can be mounted anywhere you want.

With Linux filesystem hierarchies you're going to run into a lot of history, conventions, quasi-standards and simply deprecated implementations.

It's a problem of "there's no bad way to do it so all options are equally fine". From this arose some "guidelines" about /bin and /usr/bin, /var, etc. but few strict rules.

For a long time there was no /media. In the '90s/2000's you would mount your CD-ROM and floppies in /mnt (e.g. /mnt/cdrom, /mnt/floppy). That was awkward as we started wanting auto-mounted things and wanted to do it from user-space. So /media/username was created to allow you to mount things with your ownership.

If it's something you want permanently mounted but not part of a pool you can put it under any location you like really. I like locations under /var as historically /var is used for things that "vary". You could just mount it in your $HOME if it's something you're going to use as a user rather than with a service.

I have a "/exports" dir for NFS mounts (e.g. /export/media, /export/storage, etc.). Just keeps it tidy and in one location.

The important thing is to use a standard that works for you and makes sense. There's not a lot of bad places to mount things. If "/mnt" makes sense for you then go for it.

Mounting locations are a convention, not a standard, mount whatever you like wherever you like. In your case, I'd mount it under /mnt/ntfs, /mnt/windows if it a windows main partition you want visible, or by drive letter if it's a secondary drive on a dual-boot system.

Or however you want. I would keep it under /mnt, but you don't have to.

Do maybe sure you have user permissions set up properly if this is a multiuser machine though

Edit: also I would interpret

If /mnt is for temporary

'temporary' as in 'may become unmounted without seriously fucking the system'

/ and /home aren't temporary. Everywhere else is

Use any you want. I've been mounting my internal secondary hard drive on /mnt for well over a year now and haven't had any problems. Previously, I mounted it on ~/Storage and it also worked fine (though only because I'm the only user in my computer; dual-user systems would result in the other user being unable to access the hard drive).

Actually since their permanent non-removable drives, I would say wherever you want to place them, if they're meant primarily for storing user-based data you can do like what I used to do which was store them in within the home directory just as specific names. Like my old setup before I went proxmox was /backups was my backup drive, /home was my home drive that stored most of my users /home/steam held all my game server drive and /home/storage held my long term cold storage drive.

In the past I've tended towards /srv/* as most mounts end up being application specific storage.

Though now it is all mounted as container volume storage.

/C:

It ultimately doesn't actually matter because in many cases these things are convention and there is no real system-based effect. So while it would be especially weird if your distro installed packages into those directories, it ultimately doesn't matter. Someone already linked the filesystem hirearchy. See how tiny the /media and /mnt sections are?

I put my fixed disks into subdirectories under /mnt and I mount my NAS shares (I keep it offline most of the time) in subdirectories in /media.

The best mounting position is /booty.

I create /data and mount my 2nd drive there using fstab.

I then mount /data/downloads under my user downloads folder so everything goes to my 2nd drive. That way I dont have to redownload anything if I redo my main drive.

Basically if I add it to my fstab it goes to /mnt. I let the system handle /media for usb etc
