Trouble Playing Store Bought Movie DVDs

Hellow.

I get an error message when I try to play a dvd in VLC.
Playback failu
DVDRead could not open the disc "/dev/sr0".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details.

What should I do?

Burnt Zorin 9.0 Ultimate to a"LightScribe" disc, now I am unable to open it and I see no desktop icon, Can anyone help? I have no clue about this "Operating System" it has turned out to be more of a headache to me.

Hi, all, I am new to the forum and quite new to Linux, I am running Mint and Kali from a USB drive, all is going well with with the software and I am starting to find my way around it.

So, now to my question, I have 15 machines which all run from a CF card and the card has multiple partitions and is a Windows Embedded XP, not that the operating system makes any difference, I need to upgrade all the CF cards from 2gb to 4gb, so unfortunately Windows isn't an option to use to copy the drives as it doesn't recognise multiple partitions on a removable drive, so I cant just remove the drive, clone it and fit the new one.

What I need is a method of cloning the drive completely with both partitions, I have read about dd but cant seem to see anything about doing this with multiple partitions, as Linux sees it as two drives when I plug it in, how can I use dd or anything else to clone the drive which is bootable and has two partitions?

At some point I would like to automate the process as I could have many of these machines/drives to upgrade, is there a way to write a program that will automatically back up the drives from a USB drive and then reinstall it, I have seen this done before but I am not sure if this method did the whole drive, just the main drive or all partitions?

A week ago, I realized that I could not boot live disks. At first, I thought that it was the optical drive not writing the disks correctly, but when I tried two live disks that I've used many times before nothing happened with those either.

I have CD/DVD drive listed first in my BIOS' boot order and I even tried selecting the optical drive in the menu when the computer started and it still does not boot a disk. Thankfully, my somewhat old hard drives are still chugging along but I need to be able to use a live disk, in case one or both die on me.

My question is, how can I know for sure what the problem is? Is there a way to test the optical drive (Samsung Super Writemaster - which has a bad rep)? Could it be my motherboard. It was bought new 2 years ago, and there are no other issues with it. Also, I have been able to create playable DVDs on my computer with the Optical drive that work perfectly on my Bluray player, yet I cannot play the movies or open a data disk in file manager on my computer. What does that mean?

I want to know that it's worth it to buy another burner, before shelling out the money when I'm already practically broke from Christmas gift purchases. Any suggestions on how to test the optical drive would be appreciated.

I created a persistent USB thumb drive boot with LUKS for drive encryption (250 MB /boot and then 7.5 GB ext3 root). There's no swap partition because this is just to store some private files.

I want to make two or three copies of this thumb drive to store apart in case one gets destroyed/lost.

When I am booted from that thumb drive, can I plug in a same sized drive and just do a

Code:

dd if=/dev/sdb of=/dev/sdc

command to make a copy of itself to another thumb drive without booting to another host OS? This way when I make changes to one (such as to update the OS, apps, or data), I could then just copy the entire thumb drive over to the other two while still booted in the original USB.

Or would I effectively have to shut down, boot to my normal host OS (or other), and then copy the thumb drives when not booted into them.

Hi,

Could anyone please explain as understandable as possible how could I on my Windows 8 open either single file or install (and use) entire software which is supposted to work on Linux and/or Ubuntu? I have absolutelly NO experience with Linux and have never used it. Honestly, I don't know if there is any difference between Linux and Ubuntu. I want to be inside my Windows 8 while using Linux files/sofware. The only solution I could think of are actually two but neither of them is useful for me:

1. Vmware (i don't know how to use it)
2. Rent remote computer (vps/rdp) with linux OS installed (this would let me be in Windows 8 while being able to use Linux file/software [on remote computer] but sooner or later I would want to have Windows installed there too)

Tried program Linux Reader but didn't work on my Windows 8. Although I would need solution for installation/usage of software (that can be used only on linux/ubuntu), regardless of details***, the current problem is basically related to single files only: I have two files, both in IMG extension. Don't know how to open them because Deamon Tools doesn't handle IMG. The problem is that filesystem in one of them is "Linux" and filesystem in another is "142". The error I am getting when I try to open them is:

"File with harddrive/disc snapshot is corrupted."

But this is most likely because they are supposted to be used in linux environment, hence such question.

*** when i said "details" I was referring to basically anything: type of software, size, purpose, whether or not it needs network connection, whether or not it contains logging in (username password, etc) requirement, etc.

The following solution for current situation (quoted error above) works only partially:

http://www.sysprobs.com/simple-tip-h...thout-software

I am able to open/run/mount IMG if I do what is described on this link (im basically opening iso in this case - see the website) but when opening the virtual drive, the following error message proves that the file can be used in linux/ubuntu only:

"Windows cannot access that drive. Drive could be corrupted. Make sure the drive is in condition that can be recognized by Windows. If drive isn't formatted then format it before usage."

Would need detailed instructions, for total beginner, who has never used linux/ubuntu, what to do in such case: how to use in win8 files/software that are supposted to be used in linux/ubuntu. Also answer on how to open IMG would be highly appreciated.

Kindest regards and thank you a million in advance.

I've just started tinkering with Linux and have a question about installing it to my current machine.

I'm running Win 7 Pro and have installed Oracle VM Virtual Box on the C:\ drive which is a 256 GB SSD. I want to create a 15 GB virtual hard drive on a second internal hard drive that has more space on it, and install Zorin 9.1 to it. Currently my C: drive is about 60% full and I'd rather not fill it up past that.

So my question is: Can I run Zorin off of a hard drive other than the C: drive?

Thanks for your consideration.

Lots of posts on internet about flash drives ending up read-only in Linux after using on a windows or mac systme. Gather it is a problem with incorrectly ejecting or the ejection being poorly done.

Usually I can go back to the box and re-eject and all is well. This time even GParted and the resident fedora 21 Disk Utility programs did not even see the drive (which Was visible under "files").

Using disk utility on the "offending" machine, it seems there were many files that were truncated (due to some eject issue? Note the ejection was done "according to Hoyle" ); regardless the flash drive was still read-only. Howeverk, re-trying GParted, which now recognized the drive, the drive was unmounted checked. Some repair was necessary. Currently, I can read, write and copy within the drive.

However, the drive itself is still only read-only for all but the owner (which is not even root). I cannot copy any file to the flash drive. Chmod does nothing (no matter if root or other user tries). I suppose I should be satisfied for the access there is, but if anyone has any more suggestions, it would be great.

Thanks in advance for any info/interest

Apologies. I've been out of Unix for 14 years, and the gears have rusted. Also, Unix has changed - enough similarities to memory that I'm pretty comfy though.

Glad to see lots of info available via google. However changes are going to take getting used to. Have set up a testbed of 3 nearly identical machines, hoping to make an (at home) private network where I can automate installs and set-ups using NIS and NFS (Similar to work I once did).

Have found useful scripts interspersed with comments, would like to copy and paste them to a bash script that:

Reads the line.
Echos the line.
Reads the reply.
Executes what is typed.

Essentially, by making myself type (or copy & paste) the commands I think I'll become familiar.

Figured I'd use a spreadsheet, select the file, and paste into column B of the spreadsheet. In column A I'd paste:

echo "

and in column C I'd paste:

"

Then I'd cut and paste into a text document, insert the lines:

read A
$A

behind every command necessary to the actual task.

Figured I'd have to escape the ' and ".

Ran a test (test.bash):

#!/bin/bash
for i in `seq 1 10`;
do
echo "Enter a command:"
read A
echo "Trying $A"
$A
done

works fine when I type

ls -alg

but not so when I type

ls -alg | grep dwrx

so I'm wondering if someone has a suggestion?

Thanks for any ideas.

gold finger was kind enough to share this with me a while ago:

Quote:
Do backups to either another HDD, partition, or a USB stick (if big enough to hold your data). Can use program to make an initial backup of /home/gregory; then use it to periodically update that backup by having it sync between your installed Xubuntu /home/gregory and the backup copy. The sync function will just copy over things that are new or changed, rather than copying everything all over again.

Assuming your Xubuntu filesystem is Ext4, example of doing initial backup would be something like this:

* Spare USB with large partition formatted as Ext4 and labeled "BACKUPS"
* Open luckybackup and choose "Backup" function
* "Source" = /home/gregory
* "Destination" = /media/gregory/BACKUPS (might be under /media/BACKUPS)
* Check box to not create new directories (it will just do exact copy of source)


After initial backup, either make a new task for syncing, or modify the backup task to turn it into a syncing task instead. Then use that periodically to update the backed-up /home/gregory.
I've downloaded Luckybackup and have been experimenting with it but I'm still not sure the best way to go about using it as a backup. Like in gold finger's advice, why would I check the box to not create new directories? It seems to me doing it without checking the box re-creates things just the way they are on my computer. When I check the box it just takes everything out of the folders. Seems confusing (and unnecessasry). And I have a really hard time finding the errors after a run and when I do find them I do I don't know what they mean. And so if I backup the source destination it makes an exact copy on my destination drive (with folders if I don't check the box, without if I do). Then if I do that as an ongoing thing, I will be backing up all my data with each run (which I'm assuming would be much more time consuming), whereas if I choose 'syncrhonize source and destination' it will only backup the changes in my source and usb drive (which would be my destination drive)?

Is that the idea?

And I noticed that Lucky did not want to transfer things with colons in them. Googling around somebody said that problem would be taken care of by switching to ext 3 or ext 4 for formatting the destination drive (as gold finger suggested). Is this a good idea? (I've always felt comfortabel with FAT because if I needed to plug my flash drive into Microsoft it would work (as well as with Linux).)

So the first time I use Lucky I choose "backup source inside destination" and of course the source and destination. Should I check the "Do NOT create extra directory" box? (Again, that seems off as 95% of what I'll be backing up is in folders.)

Then after I've done that, I choose the snyc option?

A lot of stuff. I know. Thanks.

PS. As a slight complication I have the data (basically the "home" folder) of my two computers (work and home) synced via Copy.com.
