Ubuntu :: Small Tool To Verify A Burned Disk?

Mar 10, 2010

I'm looking for a small terminal tool to verify a burned disc and compare it to an iso file.

I googled for verify burned disc/dvd - no mateches.

There is a thread, which tells how to do it in k3Burn - but I need it on terminal to use it with ssh.

Ubuntu Installation :: 10.04 Desktop Edition - Burned Disk Not Readable

Apr 30, 2010

So I downloaded the Ubuntu 10.04 Desktop Edition and burned it to a disk. Shut off my computer and restarted it, booting from the CD Drive. It couldn't find it. So I thought maybe there was an unrecorded write error so I burned it to a second disc. Well after burning it I noticed I can't even see the disc anymore. It doesn't seem to be recognized at all. That explains why it didn't boot from CD.

But what I want to know is why on earth is it basically going invisible and not working? I've never had a problem with burning discs, especially Ubuntu stuff... So why...? Well I just booted up the CD on a different computer and it seems to be working fine. So it appears that my computer simply has ceased to see bootable discs or maybe its just non-empty discs.

OpenSUSE Install :: YaST2 Says 15GB Of Disk Is Too Small?

Jan 12, 2010

I'll get to the point straight away... I'm trying to install OpenSuse 11.2 on a HD that already has Win 7 on it.I left out 15.52 GB of space just to install Opensuse but when I select that partition (which of course is empty) and tell YaST2 to install OpenSuse there it tells me there isn't enough space. Is 15 GB not enough!?inimum requirements where supposed to be 3GB I think...S this is how the disk is devided... Primary partition of 50GB for win 7, 400 of Logic partition for Programs, and supposedly 15GB for OpenSuse...

Programming :: Small C++ Project - Disk Sector Viewer?

Jun 2, 2011

I have a small project that I am trying to do for my job to help us out. Basically, I need to make a tool that lets me view all the sectors of a hard drive in hexadecimal format to make sure they are all zero after a low-level format. I need it to be very minimal, and display the data in a way that I can scroll down and skim through the sectors. Doesn't have to be pretty, just functional.I need it to do more things down the road, but this is the first hurdle I need to overcome. I would like to create a GUI interface so it looks nice, but first I am only concerned with the sector viewing function. I am not entirely sure where I should start.

I see there is a tool called dd I could use to read the hard drive and I am wondering if I need to use that, or if I can just open /dev/hda as a file and be able to view all the sectors that way.Also, just to clarify, I am wanting to write this tool for linux,specifically DSL. I need it to be a very small distribution that can be loaded quickly from a usb drive, cd, or over the network with PXE.

General :: Tool That Shows Disk Space Of Mounted Volumes Graphically?

Dec 20, 2010

I am looking for such a tool, very much like the one that is on Windows 7, where you can basically with one glance see how much of a volume is occupied (graphical bar) and that for all mounted volumes. I have been looking for this, but so far I have not found it.Also, important: that it is auto updated. So that it is not like a report that was generated and then does not change anymore, but a live thing

General :: Ubuntu: Tool For Displaying Disk Activity In General And By Process?

Oct 12, 2010

My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.

I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.

Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

Ubuntu :: Last Few Burned DVDs Won't Mount?

Jul 30, 2010

I've been backing up some data recently because I'm planning to upgrade to 10.04. It had been going well until today. I burned a couple DVDs, tested them, and they were fine. I burned another one, tested it, and it wouldn't mount. Got the following: "Unable to mount media. There is probably no media in the drive." (Was using K3b).

I tried the same one again, this time using GnomeBaker. Seemed to burn alright, but once again would not mount when I tested it. So, I thought maybe it's just this one particular folder. I tried to burn a DVD with completely different data. Same thing, seemed to burn OK, but again it will not mount.

I went back and re-tested the DVDs that worked OK earlier today, and these ones are still mounting. Any ideas? Did my burner suddenly go bad? Or does someone know of any other possibilities that hopefully could be fixed? -using Verbatim 16x DVD-Rs (burned on 8x)-Lite-On SHW-160P6S

-Ubuntu 8.10
-755 MB RAM
-Intel Xeon CPU 1.70GHz
-used no multisession (or finalized in Gnomebaker)
-used linux+windows filesystem

-I was burning mostly video files (.avi, a couple of .wmv, couple of text files, subfolders with other .avi, etc.)--basically the same type of data whether they could mount or not.

Ubuntu Installation :: Burned DVD Of Version 9 Not Recognized

Jul 11, 2010

I've been trying for days now to install Ubuntu on a Dell Dimension 5100 desktop. It's got a 2ghz processor, ATI graphics card and 512 ram. It has a DVD drive that it boots from. Here's the problem. I have Ubuntu 10 burned on a regular CD and I have Ubuntu 9.1 burned on a DVD. I can boot this Dell up using the CD. It goes through the regular install, gets to 23% then tells me that it can't recognize the CD/DVD device or the hard drive. I've re-seated cables, I know the hardware is all good, this is my media computer that Ive had attached to my TV now for a year. It was running fine 3 days ago before I got the great idea to convert it to Linux.

Now...once that fails I try to put in the burned DVD of version 9. Again the computer boots, I tell it to boot from the DVD...but this time the computer acts as if that drive doesn't even exist. It simply can't find the DVD drive anymore once I put a DVD into it. Is this a problem with the basic reading?? It'll read a CD but not a DVD. If I let it boot all the way to the live Ubuntu CD, the DVD drive is recognized just fine, reads DVDs, etc. Is there another solution, something I should be trying? I need this comp on Ubuntu. I've already converted all other systems in my house and this POS is the only abomination still using windows.

Ubuntu Multimedia :: DVD ISO Plays, But Burned DVD Is Jerky?

Oct 15, 2010

I have an odd problem with a copied DVD. I started with a commercial DVD and created an ISO file. The ISO file plays perfectly with VLC. I take the ISO file and burn it to a DVD+RDL without error. The burned DVD will not properly play on my computer or DVD player. It loads, but the menu is jerky and full of video block artifacts. The menu does not function properly. I tried this more than once with different software, including going directly to the DVD. I am using a drive that worked before, with the same stack of DVD+Rs that I used before.

Here is where it gets interesting: I can take the non-working burned DVD and copy it to a new ISO file. The new ISO file works fine with VLC. Obviously the data is getting properly copied from the source DVD, and it must be good on the burned DVD, but it won't play properly.

Ubuntu Installation :: Checking Md5sum Of A Burned CD?

Dec 26, 2010

I checked the md5sum of the iso using winMd5Sum utility, it is OK.

To check the CD, right clicked the md5sum file in it, send to winmd5sum, and then copied the corresponding hash from the ubuntuhashes page into the bottom text box, and compared. The message box says md5 sums are different. Now the question is, have I done it correctly, I mean, is this the way to check a burned CD, OR, is there another way to check md5sum of a burned CD?

Hardware :: Burned DVD-R Cannot Be Mounted

Feb 10, 2010

I am able to burn DVDs with either Brasero or k3b, but opensuse then cannot mount them .Those DVDs do contain the burned data since I can see it and read it on a Mac.Never had any problems reading other DVDs. This is the first time I burn my own DVDs. So is there something particular that I should do when burning in order to make them readable on Linux? What shall I check for? The error message mentions a 'wrong fs type'. I didn't format the DVDs before burning them - just used them as purchased - can that be a problem?

Hardware :: Can't Boot From CD If It Was Burned?

Mar 3, 2010

So I picked up a new (too me) laptop Dell Laditude C640, Tried to install Ubuntu 9.10 on it, won't boot, all bios setting correct. Couldn't figure it out. Went through my stack of distro CD's Oddly I found It WOULD boot FC12, and a Debian Lenny Netinst CD (But not the full install one). Even weirder. Assumed bad CD, re burnt with new;t DL'd iso, Nothing. Tried on different media, Nothing. Burned it on my GF's laptop (Win7) WORKED! WTF kind of crap is that? what can it be doing that K3b / Brasero isn't.

Ubuntu :: Ownership & Permissions Change When Files Burned To DVD+RW?

Jan 18, 2010

After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?

Ubuntu Multimedia :: Data Verified Automatically After Being Burned To CD With Brasero?

Jul 31, 2011

I set up a data project to burn a bunch of files onto a CD. I want to backup the files. I went to edit > plugins and selected "File Checksum" and set it to SHA1. Will Brasero now automatically (as part of the burning process) calculate and then compare the SHA1 for the file on the HDD with the file that is burned to the CD? If the two SHA1 comparisons do not match then Brasero will kick up a dialog window alerting me? Do I understand how this works correctly? as long as the plugin is enabled this is all automatic? Is the "Image Checksum" plugin only in use when I am burning an ISO?
