external drives refuse to mount

Postby dove » 2017-12-01 00:54

I'm running stretch with opnbox . external drives (SD cards, thumb drives, external hard drives) refuse to mount suddenly saying (Failed to mount " Volume" Not authorized to perform operation). everything was working fine. Any help would be very nice

Do you think it would help somone to help you, if you give some details about how you are trying to mount them ? I can not guess why the devices don't
mount based on what you have said.

Example, this is how I mount a device, and it works:
Code: Select all
$su
$password:
#mount /dev/sd1i usb
#
#exit
$cd usb
$

Of course , in your case you would be showing how you try to mount the device, but it does not work.
Code: Select all
man mount
Might help.

File manager in your system?

That is my point, without knowing anything about how the OP is trying to mount
the devices, everything else is just guessing.
I use openbox myself, but I mount devices manually, if a file manager is involved, we need to know which one, also:
everything was working fine

What did the OP do, that might of changed things, maybe a recent update ?
I wish people would be more clear and include details that we could use to help.

P.S. This is not of much use:
Please post output of....

Code: Select all
    fdisk -l

Code: Select all
$ fdisk -l
fdisk: option requires an argument -- l
usage: fdisk [-egvy] [-i|-u] [-b #] [-c # -h # -s #] [-f mbrfile] [-l # ] disk
        -b: specify special boot partition block count; requires -i
        -chs: specify disk geometry; all three must be specified
        -e: interactively edit MBR or GPT
        -f: specify non-standard MBR template
        -g: initialize disk with GPT; requires -i
        -i: initialize disk with MBR unless -g is also specified
        -l: specify LBA block count; cannot be used with -chs
        -u: update MBR code; preserve partition table
        -v: print the MBR, the Primary GPT and the Secondary GPT
        -y: do not ask questions
`disk' may be of the forms: sd0 or /dev/rsd0c.

But any way, thanks for trying to help the OP, without any details I don't
see how any one can really help.
The output of :
Code: Select all
$ lsblk -l
NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda    8:0    0    50G  0 disk
sda1   8:1    0    49G  0 part /
sda2   8:2    0     1K  0 part
sda5   8:5    0   996M  0 part [SWAP]
sr0   11:0    1  1024M  0 rom 
$

might help, it would show if the devices are detected.
