Flash mount as read only

Hello,
I was searching last three hours for solution, but without results. Problem like in topic name. Btw I want to have an option to automatically mount all sticky devices like usb, flash etc in read, write & execute option, I'm the only user of machine. Internet have some one use tricks but nothing worked in auto mode. I'm sorry if it is stupid noob question, but don't want to broke configs or something like that. I was trying to install usbmount and udisks but synaptic want a CD with Jessie snapshot so it also didn't work

dmesg | tail:

[   38.587187] scsi 5:0:0:0: Direct-Access     Multiple Card  Reader     1.00 PQ: 0 ANSI: 0

fdisk -l

fdisk: cannot open /dev/sda: Brak dostępu
fdisk: cannot open /dev/sdb: Brak dostępu

"Brak dostępu" means lack of access.

Help, please?

Re: Flash mount as read only

Curious, but does your /etc/apt/sources.list have a line similar to this:

#deb cdrom:[Debian GNU/Linux 8.1.0 _Jessie_ - Official amd64 NETINST Binary-1 20150606-14:16]/ jessie main

if so, comment it out as I have or directly delete it.

Are you using Jessie?
If you are I'll move this to "Help & Support (Stable)"

Yep, it have and I commented it out, so one weird thing less I'm using Hydrogen with Jessie. Still no luck with a mounting, other mounted devices do the same thing and however usbmount helps a little I don't want to use it, if there is any other option.

Re: Flash mount as read only

 setting readonly to 0 (off)
 readonly      =  0 (off)

but still I can only copy things on this device, not cut or remove.

Re: Flash mount as read only

Erm, when I click right button of the mouse on file or folder which I have on this flash card, I have some options, like you know "open", "send to", "cut', "copy", "remove" etc. Options like "cut", "move to trash", "remove" and "change file name" are inaccessible.

Re: Flash mount as read only

After fresh install usbmount allowed me to have all right-click options, but one reboot later it didn't work again. I can't delete from terminal, here is the message:

rmdir: failed to remove 'Books': Permission denied

Re: Flash mount as read only

I used:

LC_ALL=C rmdir Books

as a regular user, without sudo. The output was:

rmdir: failed to remove 'Books': Permission denied

The device was mounted automatically, I didn't mount it via terminal commands only stick it in the laptop.

Re: Flash mount as read only

OK, try mounting it manually (do this from a TTY to stop automounting).

Plug the device then run these commands:

sudo mount /dev/sdb /mnt
sudo rmdir Books

This presumes the device is assigned to /dev/sdb -- change this if needed (use `dmesg|tail` to find the block device assignation).

Re: Flash mount as read only

Ok, I deinstalled usbmount and was able to remove one of the files with commands you gave me. For now right-click options are also working, which is really weird because I installed and deleted usbmount few times before and I didn't changed anything else O.o Seems so that usbmount was also blocking rockbox utility, because after deinstallation it also started to working properly.
