Every now and then I buy a flash drive and find that when I mount it
it's owned by root and read only except by root. I can, of course,
change that by using chown and chmod, but that only lasts until I
unmount the drive. Generally, I need to reformat the drive to get it
working properly. And, it's not just Fedora; my sister uses Xubuntu,
and has the same issue. Does anybody know a way to keep this from
happening, or to fix it without reformatting?

What filesystem is on it and how are you mounting it?

*Sigh!* The drive we're having trouble with works Just Fine on my Fedora box, but
not on my sister's Ubuntu box. Not a Fedora issue.
FWIW, I have a Ubuntu VM and the same flash drive that I used on Fedora works the same way
on
it. The system mounts it for me, as me. It is ubuntu 20.04 if that makes any
difference.

Most of the time, flash drives mount properly for my sister too. Once
in a while this comes up for her and/or for me, and I was hoping to get
a handle on how to deal with the issue once and for all.

The next time it happens to you check which file system type is on the drive.
FAT and VFAT don't have ownership written to them as Samuel explained. And, as I
said, I've never
encountered issues with them.
However, file systems such as ext4 do carry ownership information.
So, if a flash drive was formatted with ext4 and not previously mounted, or ownership
wasn't established it would mount as root:root
I have a flash drive which was formatted ext4 and used by maria who changed the top level
ownership.
So, when I plug it in and hit "mount" it get mounted....
[egreshko@meimei ~]$ whoami
egreshko
[egreshko@meimei ~]$ df -T | grep media
/dev/sdg1 ext4 7654088 17232 7228332 1% /run/media/egreshko/ADrive
[egreshko@meimei ~]$ ll -d /run/media/egreshko/ADrive
drwxr-xr-x. 3 maria maria 4096 Nov 26 16:46 /run/media/egreshko/ADrive
The expected behavior.

It seems what's described here is that, for some odd reason, the flash
drives get mounted occasionally as read-only, so this is not an ownership
issue.

You don't think someone could mistake not being able to write to the drive because of
an ownership/permission
as it being "read-only"?

Remember, in the initial post it was stated.....
"Every now and then I buy a flash drive and find that when I mount it it's owned
by root and read only except by root."

"Every now and then I buy a flash drive and find that when I mount it it's

Well, this /has/ happened to me occasionally. I have this whole setup going
where I have a radio attached to audio-in, a daily cron job that records
audio, and converts it to mp3.
I plug in my mp3 player in the evening, and another cron job copies the
files to the mp3 player at preset times, expecting it to be automounted.
A few times in the past it failed, I looked and found that, for some reason,
the mp3 player was automounted read-only, mount showed the "ro" flag.
Unmounting and plugging it back in remounted in normally. Rather odd, but it
wasn't enough of a hassle to look into this further.

The permissions are full for root, and r-x for everybody else.
Which isn't equivalent to "read-only". A "read-only" file system
will not allow the root user to
write to it either.
As I mentioned, I got the same expected results in Ubuntu as I did in Fedora for the each
of the
file system types tested.

Most of the time I do too; that's why I didn't test it on Fedora before
asking. My sister has an account at the Ubuntu forum, and I'll let
people here know if they come up with anything.

Oh, additionally, a "read-only" file system will not be reflected in the
"permissions" as there is
no relationship.

I'd presume VFAT, and I'm just inserting the drive and letting the OS do
its thing, and my sister's doing the same way on Ubuntu.
I've never had a problem with a FAT formatted drive. FAT doesn't have
internal permissions, so if it's mounted by your user, then you have
full permission. if you run into this problem again, then get the line
for this drive from the "mount" output.

I too have no problems with VFAT. Just inserted a flash drive in my F33/KDE system. The
"Disk/Devices"
systray widget had a mount button and upon hitting it.....
[egreshko@meimei 4A00-13F0]$ df -T | grep vfat
/dev/sdg1 vfat 7840800 640 7840160 1%
/run/media/egreshko/4A00-13F0
And...
[egreshko@meimei 4A00-13F0]$ ll /run/media/egreshko/4A00-13F0/
total 64
drwxr-xr-x. 3 egreshko egreshko 32768 Dec 13 2019 Android
drwxr-xr-x. 2 egreshko egreshko 32768 Dec 13 2019 LOST.DIR
So, the system mounted it for me, as me.
