Re: [Dorset] External HD - Permission denied
Clive, thanks for the directory listings. My solution would have two steps. While the external disc is mounted, run: $ sudo mkdir /media/CAW1/clive $ sudo chown clive:clive /media/CAW1/clive User clive should now be able to store anything in /media/CAW1/clive (but not directly in /media/CAW1). To tidy up, the file you've already put in /media/CAW1 can be moved into /media/CAW1/clive by $ sudo mv /media/CAW1/IMG* /media/CAW1/clive That's my solution; if it doesn't work please send the output of $ ls -lR /media I think Ralph had some simpler solutions ... Leave lost+found severely alone, for it is used (IIRC) by fsck, the program that occasionally checks the integrity of filesystems. Best wishes for your trip abroad!

Re: [Dorset] External HD - Permission denied
Hi Ralph John Sorry for the slow response but been very busy trying to sort out a mix-up with DVLA and my driving licence photo. It turned out they gave me a wrong instruction so I'm now awaiting a new licence before going on the continent id 8 days time!! Result of the 2 instruction asked for are below:- $ ls -lR /media/CAW1 /media/CAW1: total 2512 -rw-rw-r-- 1 clive clive 2555103 Feb 23 14:33 IMG_0924_v2.JP2 drwx-- 2 root root 16384 Mar 6 13:42 lost+found /media/CAW1/lost+found: total 0 ls -l /media/CAW1 total 2512 -rw-rw-r-- 1 clive clive 2555103 Feb 23 14:33 IMG_0924_v2.JP2 drwx-- 2 root root 16384 Mar 6 13:42 lost+found Have managed to put a test file onto the external disk but can't remember how, tried several things and got it by luck. Not sure if the problem is fixed but will try the code:- sudo chown $USER:$USER /media/CAW1 chmod u=rwx,go=rx /media/CAW1 when on holiday. Will report back while away as will not have time to concentrate on it before then. *C A Wills* /Powered by Linux Open Source Software/ On 07/03/13 18:24, Ralph Corderoy wrote: Hi Clive, John's pointed out the underlying cause.

Re: [Dorset] External HD - Permission denied
It'll be to do with permissions in PolicyKit to disallow users from doing so. There are a few solutions: 1. Fix in policykit to allow you to edit volumes (the tool depends on your DE, it's usually in the relevant settings tool). 2. Format to VFAT and it will automount as user 3. Edit the fstab and add it in, with an option of user,auto 4. Do everything as root on the disk.

Hi Peter, /dev/sdb1 /media/CAW1 ext4 rw,nosuid,nodev,relatime,user_xattr,barrier=1,data=ordered 0 0 For those of us not so hot on this stuff, is it related to nosuid,nodev and then what do we do? It's not, no. :-) mount(8) explains that nosuid means setuid, set user ID, and setgid, group, permission bits should be ignored and nodev stops inodes that are character or block devices from being treated as such. IOW, don't trust the contents of the filesystem too much.

[Dorset] External HD - Permission denied
Hi all Today I bought a small external HD from Novatec in Portsmouth, to back-up my laptop before re-formatting and re-installing the laptop. Plugged it in and it was not recognised by the system, so checked with Gparted which confirmed it was not formatted. Formatted drive to EXT4 and gave it a label 'CAW1'. For the above I used a MINT 14 'live disk' with Gparted and checked the HD was not mounted. Now recognised when plugged in, but it will not accept copying a file onto it, reports that 'Copying file error - Permission denied'. Checked on main PC, same result. Right click on disk and checked permissions tab; reports are 'permissions not available' or word to that effect. How do I make the disk available to any person or machine please? At the moment it's a useless block! Not had this before when formatting a HD. Is it 'ROOT' that's the problem? -- *Clive Wills* /Powered by Linux Open Source Software/// -- Next meeting: Bournemouth, Tuesday, 2013-04-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
