The dreaded read-only problem

(1/2) > >>

Tyrannocaster:
I've been using an external HD to transfer files between my linux system and my windows PC. Tonight it wouldn't let me write to the disk. No matter what I did I got errors like chown: changing ownership of '/media/MYNAME/STORAGE': Read-only file system
(STORAGE is the name of the disk.)
When I look in the GUI properties tab it says I have read and write access but no groups have anything but read access. However, I plainly do not have write access. I've looked online for the last hour and I know this is a common issue in linux, but I've never run into it before and so far all the terminal commands I have seen suggested don't do anything useful; the disk stays read only. I have to get this working again!

I can write to it fine in Windows.

I can write to it fine in Windows. The disk is formatted as FAT 32.

Why did it quote me instead of modifying the message? And after telling me the forum is unavailable twice, too. Hiccups in everything tonight!

The Manual has all you need for this task.

Tyrannocaster:
That link talks about getting a disk to mount. This one already does that, it just won't let me write to it. And it was working fine yesterday, so something changed. I will try the Disks app again later (no luck there yesterday, though) when the usb dock is not being used to backup my Windows partition; right now I can't insert the funky disk. More later.

EDIT: just inserted it again and it let me write to it once. I have changed literally nothing since yesterday. I wonder if the disk itself is getting wonky. This is certainly not consistent behavior! It let me copy a file to it, but it won't let me delete the file once it's copied. This seems strange. And now once again it says the disk is read-only.

Going into Disks, I see that compared to the mount options shown in your link (users,noexec,nosuid), mine says nosuid,nodev,nofail,x-gvfs-show. Is this important? I left it the way it is until I know more about what I'm messing with. After saving the Disks changes the drive is still mounted but still also read-only.
