unable to mount external USB drives after upgrade to 12.10

Asked by James on 2012-10-30

Both my external HDD and my thumb drive give me an error Unable to mount Adding read ACL for uid 1002 to '/media/admin' failed: operation not supported.

It may be important to note that my ext HDD and Thumb Drive both appear in my device list, but when I click on them it says 'unable to mount'

When I used terminal, typing in sudo df -ah, I got the following information.

Sorry for the double paste :(

Subin Hutton (djlynux) said : #2

Hi James, can you provide the out put of the following command

ll /media/

Warren Hill (warren-hill) said : #3

Hi James

Subin's command will tell us if the drives are mounted in the expected place but will not help us find them if they aren't

Can you give us the output of the following command please

lsb_release -a; sudo fdisk -l; mount | grep ^'/dev';ls -la /media/

Hi James,

you're most probably having this bug: #1048059 Adding ACLs to /media/$user does not work.

What you can do is the following:

1. Open a terminal window

2. Type in the following commands (whithout comment lines):

# Add a folder
sudo mkdir /media/USERNAME

# assign the folder to my user
sudo chown USERNAME.USERNAME /media/USERNAME

Automounting volumes should then work again.

Does it help?

Kind regards,

Stefan

James (jimimack-fl) said : #6

I am not certain if USERNAME should be jimi or dave-desktop. Both are admin accounts, I'm signed on as jimi.
But as you see something is still amiss. The thumb drive and ext. HDD still appear but give the same error as before.

the following is what happened when I tried it:

admin@dave-desktop:~$ sudo mkdir /media/jimi
[sudo] password for admin:
admin@dave-desktop:~$ sudo chown jimi.jimi /media/jimi
chown: invalid user: `jimi.jimi'
admin@dave-desktop:~$ sudo mkdir /media/jimi
mkdir: cannot create directory `/media/jimi': File exists
admin@dave-desktop:~$ sudo chown jimi.jimi/media/jimi
chown: missing operand after `jimi.jimi/media/jimi'
Try `chown --help' for more information.

Hi James,

your posting clearly reflects that your computer name is dave-desktop and your username is admin. Please try:

1. sudo mkdir /media/admin

2. sudo chown admin.admin /media/

James (jimimack-fl) said : #8

Thanks that solved it.

I sign in as jimi and it has always appeared as "admin@dave-desktop.

I want to thank you for clearing this up for me.

James (jimimack-fl) said : #9

Thanks Stefan Czinczoll, that solved my question.
