Gnome - USB Sticks Read only
« on: 2017/12/09, 17:37:22 »
Hi,


why does Nautilus mount USB drives read-only and how can I fix this ? Dunno what happened, this worked without a problem before.


Boy, am I pissed. Wasted a full day trying to split a 2h mp4 into 3 parts. Didn't work and now I can't port it to Windows and give MovieMaker a try...  >:(


Have a nice weekend,
Stephan

That's intent. You have to unmount the stick before you could unplug.

"...port to windows..." - is that stick fat/ntfs? In which groups is your user? What are the owner/group permissions of the directory /media/yourusername/ ? Is ntfs-3g installed with the tool 'ntfs-config' ?

Why is the filesystem of importance ? It worked fine no matter what fs.

I've tried this with my Fedora installation -> same problem. And this wasn't updated for a month, at least.


I found something about running dosfsck and tried that. dosfsck found and corrected some stuff but it still gets read-only access. Well, I guess I have to re-download that 5G file...  :(

Before downloading a second time on a slow connection, have you tried to work as root in terminal? Such as remounting the stick with -o rw, or creating a directory as root and copy the file? Windows should not bother who owned the file on linux.

(OT, splitting large videos with ffmpeg worked for me always like this: https://stackoverflow.com/a/35133730)

Hi,


you asked for the group memberships too. Sorry.
Code: [Select]

oppa@oppa-hex-ssd:~$ groups
oppa lp dialout cdrom floppy sudo audio dip video plugdev users fuse netdev systemd-journal scanner
Nope, didn't try any root console voodoo. :) And ffmpeg showed up during my searching too, something like starttime and duration. I was too lazy to do the math and I think writing to vfat usb drives HAS TO work.


Thanks,
Stephan


PS: MovieMaker was really easy: Open file, set marker (left mouse click), click on split button - done.

LOL  :o


Do the same thing over and over again and expect a different outcome eventually.


Just tried again and now it works. File is being copied.


Have fun,
Stephan


PS: Well, I did a d-u yesterday, maybe the fix was in there.
