10.04 and Memory sticks and digi cameras?

[Mr Gates]

I plug my memory stick (2gb generic) in my computer and it does recognise it and I can view the contents but I cannot delete anything? Any ideas.

Also I plug my camera in and it does not even recognise it!

I have just upgraded to 10.04 from 9. Using Ubuntu 9, they both worked fine no problems.

it appears non of my external drive can be edited /deleted or files added. I try and unmount and get a unable to unount usb1 error "umount: /media/usb1 is not in the fstab (and you are not root)" in more details.

Any idea's

Find the mount points for those devices.. typically in /media/disk or /media/disk-1 etc.. sometimes /media/usb etc.. once you know the mount point you will have to change the ownership of the drives.. make sure they are plugged in and then

sudo chown -R <username>:<username> /media/<mount location>

Now test read/write capability .. if it still doesn't work then

sudo chmod -R 777 /media/<mount location>

That changes permissions for the owner and everyone .. some will object to the 777 permissions but on external devices like usb keys, drives etc you typically need access to them on different machines.. possibly linux machines.. 777 will give access to everyone.. windows doesn't honor unix/linux permissions settings.

Changing permissions can't work on a vfat file system.
The problem is that root mounted the partition and only root can unmount it.
I've been searching for a solution for that since I upgraded to Lucid Lynx and nobody seems to agree on what the solution is.

Julio is right I am afraid. tried both of those options already. although I am fishing around in the dark and dont know really what I am doing.

I have managed to unmount them. by going to the /media directory and I think "sudo umount /media/sdb1"

however I now cannot mount them!!! and get this error. I get this same error in terminal and gnome interface

Unable to mount sdb1
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

annoying...

This is a copy of fstab file too. just for info.. as I think this might be important

it is easy to unmount. getting them back is also a problem

I unmounted by going to terminals and going to my /media folder and using the sudo umount command.

"sudo umount /media/sdb1" .. I think that is what I typed anyway.

[Mr Gates]

when I remove the disk and plug it back it, I get this error.

Failed to mount "UDISK 2.0"
mount: only root can mount /dev/sdg1 on /media/sdg1.

another guy here having the same issue... I feel better for knowing I am not alone.. (http://ubuntuforums.org/showthread.php?p=9220146#post9220146)

[Mr Gates]

I have the external usb hard drive mounted again now. go figure. turning it on and off worked a treat however still cannot update anything. Root is good and I have no user rights at all. so back to square one

[Mr Gates]

update.... If I go to terminal and type "gksudo nautilus"

this opens up an explorer screen with root privileges. I might be able to do so some thing from here. watch this space

[Mr Gates]

going in through nautilus does allow me to delete/rename etc however I still cannot change access rights on folders for my normal account, so although I have a work around. this is still a pain.

[Mr Gates]

kinda found a solution for me anyway...... THIS DID NOT WORK!!! false alarm the permissions now on the drive are all over the place. I cannot create folders but I can delete!

go to fstab

so terminal mode.. cd /etc/
sudo gedit fstab

Mine stated this...

/dev/sdb1 /media/uni vfat defaults 0 0

change "defaults" to "uid=your uid,gid=your gid"

my iud/gid say is jones so mine looks like this now...

/dev/sdb1 /media/uni vfat uid=jones,gid=jones 0 0

solution came from here... click here (http://www.linuxforums.org/forum/misc/49305-i-am-su-root-i-cannot-change-ownership.html)


However I am still having problems mounting a mem stick usb and a digi camera. but I will look at those tomorrow.

Mr G

[Mr Gates]

got another soultion... this time in the fstab file replace the default option with this line

iocharset=utf8,umask=000

[Mr Gates]

some what annoyingly, privileges keep dropping off the drives. don't know why. Bring back Ubuntu 9.04

[julio_grr]

I got fed-up with usbmount, went to the webpage and saw it wasn't updated anymore.

apt-get remove --purge usbmount
apt-get install pmount.

Problem solved. At least for me.

Hi!
I also did pass from 9.10 to 10.04 and I can not anymore write to my external hard drive.
I am stuck!!! I tried that last solution, but it tells me I do not have the rights. I am in a loop and see no exits.
Please, can someone tell me where to click to be able to write to external disk ou usb key again?

Thank you!

[mclode]

I had a similar problem after upgrading from 9.10 to 10.04. USB disks would mount as /media/usb1,2... etc, but I did not have permission to unmount them.

I removed the /media/usb* mount points:
sudo rm /media/usb
Now my USB devices mount automatically, with a meaningful name - and I can unmount them.

On another machine, after upgrading 9.10 to 10.04, I could only mount USB devices using System > Administration > Disk Utility. On that machine I removed the "fuse" directory from my home directory. I do not know what side effects this may have, I have not had any problems yet.

(I posted this on another thread, but I can not find it now)

[Mr Gates]

Is this a fault then and does any one know if it can be fixed in a ubuntu upgrade?

at the moment, I am still having issues but I have changed all sorts, so I am going to delete ubuntu 10.04 and reinstall an older version. one that works.
