No permission on my mobile phone

[loopinaloop]

Hi there!
I have a mobile phone and I've never experienced any major issues with it. Now, it's a disaster for me. After making a fresh install of Ubuntu 12.10 I cannot make any changes on my mobile device. I get an error message that I've no permission. What I've changed is that I've made something around 7 partitions - maybe that's the cause? I've tried to install fresh Ubuntu 12.04 but that didn't helped so I revered back to 12.10.

As always, all problems began with an update... ;)

What method did you use to install Ubuntu on the phone? What kind of phone?

How did you manage to create 7 partitions? I'm assuming some of those are logical partitions? Can you show us the output from gparted?

Are you saying:
1) You installed 12.10 to your mobile phone -- which has seven partitions on it -- and now you can't do anything on the phone?
2) You installed 12.10 to your desktop -- which has seven partitions on it -- and now you can't access the phone from your desktop?

Very different questions -- very different problems.

2) You installed 12.10 to your desktop -- which has seven partitions on it -- and now you can't access the phone from your desktop?
I've installed Ubuntu on my desktop computer and I have read-only permission on my mobile.

What phone is it? How do you access it? (USB, bluetooth). Does it show up as a 'mass storage' device or is it an MTP device?

Connect the phone, access it's data and post the output of:


sudo dmesg | tail -n20

I'm using Nokia XpressMusic via USB cable and it seems to be shown as 'mass storage' but I'm not sure (I'm using Polish language). I get following data after using your command:

There is your cause and explanation.

Seems like the filesystem is corrupt, or (which is always possible with Linux) the driver handling the filesystem is not capable of dealing with 'something there'.

I suggest you back-up your data and reformat it. Or alternatively, plug it in Windows and run a disk check (or even check that it works).

After some googling I find a more in depth explanation here (http://serverfault.com/questions/331779/how-do-i-debug-this-fs-error-on-a-flash-device) and a better way to workaround it (http://www.delodder.be/blog/linux/fat_get_cluster-invalid-cluster-chain-i_pos-0-fat-filesystem-panic-dev/) (instead of a full reformat). Furthermore, this page says it's because of an unclean disconnect. (https://help.ubuntu.com/community/Mount/USB)

Superb!
I see no problem with formatting my device. Can you drop a line or two? I'm reading those links now but I'm not sure which solution would be best. If there is one, simple method (like formatting my memory card) then I would stick to it.

Thanks a lot! With people like you Linux is no longer intimidating nor difficult. An excellent support that you provide is an antidote to any frustration that can arise while using this system without advanced computer skills. I appreciate your time. Again, thank you!

sudo fsck.msdos -aw /dev/sdb1

This command worked! Thanks again!
