I don't know exactly whats wrong, it won't play DVD's or recognize that a DVD is in it. I checked in terminal with sudo lshw -c disk, it shows the correct info for the drive but still says status:nodisk.Double clicking or right click>open doesn't do anything either. Is there something I'm missing? Whats weird is audio CDs are recognized and will play just fine.(checked with multiple DVDs

I am trying to use a second sata 3.5 HD and at other times a USB 2.5 HD. Both prove a pain to use because Ubuntu tells me their permissions can not be be determined. They have only been partitioned to ext2 on Ubuntu. This happens on 9.04 10.04 and 10.10
I have searched the web about this found many answers which just do not work.
I just did a fresh install of Fedora 11 and added Raid 1 for two additional drives during the install,
So, I have 3 drives. One with the OS, that I boot from. /dev/sdc
Then 2 others in a Raid 1 config, /dev/sda and /dev/sdb -- those are in /dev/md0
Everything with the system is fine. I can boot up, and everything runs great. So then I try to view the Raid and it looks ok when I open 'Computer'. it shows the main OS drive, and what looks like the 2000GB raid drive. So i open it and just see a 'lost+found' folder. Not surprising, b/c I haven't added anything to it. But when I right-click I can't create a folder b/c it's greyed out, I can't drop files in there, and when I get Properties on the drive itself it says 'The permissions of {driveid} could not be determined.'
My external hard drive has all of a sudden decided that it wants to be read only, meaning I can not add files to it, delete files, or even move them around. WHen I try to check the permissions, I get the error that permissions could not be determined.
I've tried changing permissions through the terminal using "sudo chmod u+w /media/filessystem", but I only get the message back "chmod: changing permissions of `/media/filesystem: Read-only file system".
I had a problem after an update and ended up re-installing Lucid. Now I don't own any of my hard drives. In the "Permissions" tab of properties they say "The permissions of "*" could not be determined". This is becoming a real problem as my the hard drive that has my Home on it is in "disc failure is imminent" mode and I need to copy everything to another drive urgently.

Is there a relatively simple way to automate this?
How is the super user determined for the dialog box that pops up when trying to perform administrative tasks, "An application is attempting to perform an action that requires privileges. Authentication as the super user is required to perform this action."? Does it always ask for the password of the default user created during the OS install, or should it prompt for the current user's password if that person is an administrator?I use likewise-open for windows domain authentication, so I typically log in as a windows user that likewise-open has added to the list of users on this system. I have given this user sudo access and added the user to all the same groups as the default user, yet whenever I perform an administrative task in gnome I am prompted for the password of the default user. Is this normal? It seems like the behavior would be to ask for the current user's password if that user is an administrator, and if so what determines that the current user is an administrator?

How do the group-ids for the devices in /dev get determined during boot up? The system must get the defaults for the devices some time during the boot process. Where are the defaults listed?
Actual reason for my question is that I need a permanent change of "dialout" to "uucp" or, even better to "dialout,uucp" in this line:

I accidentally wiped my 120GB external hardrive clean ( it was at about 95% capacity ) and I was able to recover 111.80GB back using ddrescue and all of those files now sit in a Recovery.img file.
1 ) I know I have to mount this file... yet every time I try to mount it back on my external HD permissions jump down my neck, and to add to it when I try to give my user full permissions for that drive it never works and resets to how it was.
2 )I have tried copying to .img to my drive so I could jsut worry about it later and free up some local HD space yet I don't have those permissions as well...

View 9 Replies View RelatedI use a USB drive to store most of my personal and work files, and I use it both at home and at work (two different machines, both running Ubuntu). The drive is encrypted, and is accessed using TrueCrypt (the entire drive is encrypted as a device rather than an encrypted file on the device). The TrueCrypt device is formatted as ext3/ext4.
I have a problem with certain file permissions being changed to read-only (rw-r--r--) after mounting the drive. This happens after I have used it on one computer, and then I mount it on the other. Even though I have been setting write permissions to all (chmod -R a+rw *) to get around this problem, when I mount on the other machine the write access is gone. I don't want to keep manually changing permissions; I would like the file permissions to stay as I set them.I'm using the same version of TrueCrypt at work and at home. I'm running Ubuntu 9.04 at work, and 9.10 at home.I do have different usernames on these computers, and I suspect that is the problem (but don't see why this would change file permissions for all users).
I put my 8 Gb USB drive in the slot tonight to rearrange some pictures (jpg and gif). When I attempted to cut and paste the cut function was not available. I checked the file properties and the files were all read only. I tried to change the permissions, but was presented with a message box:
[[The permissions could not be changed. Sorry, could not change the permissions of "115.jpg": Error setting permissions: Read-only file system]]

I am wondering how I would go about creating a .deb file that would extract it's contents to two different folders.

The issue I am having is that Virtual Box does not recognize my USB drives. I understand that it is related to the fact that Ubuntu cannot recognize the permissions on the USB NTFS drive. So how do I mount the ntfs drive and gain full permissions?
One post suggested that I have to join my user to the 'vbuser' group in users and groups to fix this in 9.04, but I do not have a "vbuser" group in my list of groups. I am running 10.04.
What should I do if I want to allow access to USB flash drive selectively - Say for e.g. All permissions for "root", "Read/Write" for user "A", Only "Read" for user "B" and user "C" shouldn't be able to access or mount (no permissions) the USB flash drive at all.Also I want to do it by modifying entries in some files or by some commands (so that it can be done programatically if needed)
View 5 Replies View RelatedI have a bit of a problem in my new install of Lenny (5.0.1). The machine in question was running XP and has a C: drive (system) and two other had drives (ide) one with music on and the other with videos. All were NTFS naturally.
I installed Lenny and re partitioned the system drive accordingly with swap and root partitions, no problems there.
The next phase was to convert the other two drives to ext3. The music drive has been backed up so the plan was to re-partition that to ext3, copy the video files to it and then re partition the now ex video drive and restore the music files to that.
I ran Gparted and partitioned the old music drive to ext3 but could not then mount it, it didn't do this after formating. I did not have permissions to mount the drive.
I read on a forum how to mount the drive from Terminal, going to /mnt, mkdir VideoDrive, mount /dev/hdb1 VideoDrive and presto it was mounted. However I still did not have permissions to it and could therefore not create directories.
Right clicking on the drive and showing properties now showed owner as root ~ create and delete files, group as root ~ access files, others ~ access files. All of these drop-downs are unavailable for changing.
I went into users and groups. There were groups there called mike and root so I selected both root user and mike user as members of both of these groups. Nope.
In the drive properties I entered Mount Point as /mnt/VideoDrive, File System as ext3, and Mount Options as defaults,unmask=000 0 0. The other forum I read stated that unmask is used to allow access to all users.
I then transfered these options to the Volume properties, again no joy.
I have added entries into the fstab and mtab files still no joy.
First off I want to apologize for the fact that the first several paragraphs go into something seemingly unrelated to the subject of this thread. However I want to be sure that those who choose to lend me a hand understand where I'm coming from and why I'm asking that question.I just recently switched from Windows Vista to Ubuntu 10.04. So far I've been loving it mostly. But their is one oddball thing I haven't been able to get working. That is a pair of shared folders located on my NTFS external drive connected via USB2.
The drive was automatically mounted on first boot and has full read/write access for owner (which is my username) right out of the gate. For this reason I assumed I would be good to do this.I've been unable to get it working in Ubuntu. As it stands now I've manually added them to smb.conf, added them to the Samba Server Configuration and finally by right clicking the folder in nautilus and choosing Sharing Options. All with varying resultsAt best it will show the shares under the computer but not allow access. I've also cleared out all of these for those folders to try them individually or in different orders. What I found was that using Sharing Options first gives this error and sets nothing up. But either of the other two will at least show the share albeit with no access.
Quote:'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Invalid parameter.What I've discovered is that if I use just the Sharing Options from Nautilus on any folder located on my ext4 partition or the internal NTFS partition then it will ask if applicable to adjust the permissions and though nothing appears in smb.conf that it works more or less just fine.Having played with "ls -l" I discovered that by default that ownership of the folders on the external NTFS is set to myself and that permissions are 700. On the ext4 partition ownership is set to myself and permissions on folders 711. The folders on the internal NTFS partition has an ownership of "root" and permissions set to 777
From here I tried to use "sudo chmod" via a terminal to manually change permissions for folders on all 3 partitions and I can do so for the ext4 and the internal NTFS owned by root. But no matter what I cannot for the external NTFS.The main thing is I want to know why I can't adjust those permissions on the external. I'm convinced that something to do with the way USB drives work by default must be impacting this but I could not find a single thing anywhere to confirm this much less to offer a solution.The second thing is that I installed and used mountmanager to automatically mount the internal NTFS and according to that softwares options the setup for both it and the external NTFS are the same. But if that is true then why is the external owned by me and the internal by root and the resulting permissions are completely different?
Current when my NTFS external drive is auto mounted, I can't run any executables from it.
If I unmount it and then manually do:
sudo mkdir /media/portable
sudo ntfs-3g /dev/sdc1 /media/portable
it works fine. Is there a way to make the auto-mount have "full" access so I can run applications from it?
I had an old windoz 2003 server running a few recreational web sites. I've grown tired of all the hacking attempts, FTP floods, etc. Ok.. I've grown tired of windoz period.When I set the server up, I had the operating system on one physical drive and stored all of the web files on a separate physical drive just in case I ever wanted to make some changes to the operating system.in my adventurous ways, I've dumped windoz and installed ubuntu 11, 32 bit server edition on this machine. It is running fine from what I see on the server side. The first problem I've noticed is when even attempting to navigate to localhost through the server's web browser, I get a permissions issue.
So... off to the drive where the httpd.conf file points to. This is the second physical drive. When checking permissions and attempting to change them to the correct ones for the folder, I can't change them. I've tried through the GUI and the terminal as root. Neither way will change the permissions.I've stepped back and checked the permissions on the physical drive the files are stored on. I am having the same issues with the drive itself. How in the world can I change the permissions either on the drive or the folder? Is there something I should do as far as the drive's mounting?
I own a Lacie Network Space (1) which has recently given up the ghost - I looked into getting data recovered from it and it turns out it would cost around 500quid!! After doing some research I've found out that the drive runs linux - SO, I have bought myself a HDD cradle, Downloaded an Ubuntu Live CD, taken the drive out of the network space and mounted it in Ubuntu via USB. All good up til now, I've managed to get the majority of my data off except one folder - my music folder. It has quite a deep file structure (which maybe the issue) but essentially the permissions for the top folder have a padlock and a small cross - this doesn't allow me to even read the files to copy them off. I've now tried the 'chown' command: sudo chown ubuntu /media/ 999GBfilessystem/ openshare/audio

View 1 Replies View RelatedYou know the great thing about having a debian system is that you have to reinstall so rarely you miss all the new changes that happen in the system until you have to do something like install a new piece of software and realize that fstab has been turned into spaghetti and you no longer have the slightest idea what is going on.I just got a new 1TB USB2 drive to use for backups. I plugged in it and it was recognized fine but it was formatted in NTFS which I didn't particularly want so I reformatted it as ext4FS. It automounts fine but only with all permissions set to root. I tried doing a direct chmod on the drive but that wasn't recognized. Where in the hodgepodge of HAL settings and whatnot do I set it to make the drive user accessible and mount to somewhere other than /media/disk?
View 1 Replies View RelatedTired of fat32 fragility, I reformatted a 4GB pen-drive as ext4 using Yast's partitioner. I chose format as ext4 and checked fstab options "can be mounted by user", "no access time" and "ordered journaling". I thought that these fstab options would be ineffective since a removable device won't be added to fstab. when I insert the pen-drive it auto-mounts and the folder /media/EMTEC is created (EMTEC is the volume name). The relevant mount entries are:
Code:
:~> cat /etc/fstab | grep sde
:~> cat /etc/mtab | grep sde
/dev/sde1 /media/EMTEC ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
:~>
There's no fstab entry, as it should be, and there is a mtab entry corresponding to the pen-drive, /sde1. However the /media/EMTEC as created (by udev, I suppose) is owned by root, I can't write to it. But if I change (as root) the /etc/EMTEC folder permissions so it belongs to the regular user, i can (obviously) write to it *and* it stays so *between* remounts. Haven't tried a reboot yet. What I'm not sure is if ordered journaling is OK for a pen-drive - or any kind of journaling, for that matter. Or will this significantly decrease flash memory life? Also, the fstab options set in Yast appear to be remembered by whatever creates mtab, as well as /media/EMTEC permissions. Is that so? Where are these settings kept? How does this work?
