I just bought a Sony DVD+R but I don't know if it's either +R or +RW. I assume it is a DVD+RW since the mark "RW" is written at the bottom of the disc. Same for my built-in desktop burner, it has a "RW" mark and tiny "DVD+R DL" is written below the "RW" mark.  When I'm trying to erase the content of the DVD. I used several DVD erasers, including .  Although the software is different, the result is the same, this is the error message:    I'm not sure the DVD is really "ReWritable", because the DVD Burner I used to burn DVD said the disc status is "DVD+R". That's weird, because apparently my DVD discs are rewritable. (I'm wondering it is rewritable...)  Are the discs non-rewritable? If so, could you tell me what does the "RW" mark stand for? And also, the "AccuCORE" :) Though I'm actually wanting to know is it rewrite compatible.

If you look at this product:    you can clearly see that it is a DVD+R, i.e. once it is written, it cannot be erased/rewritten.  Then what does the "RW" logo (in the lower right corner) mean? I thought it stood for ReWritable, but experimenting with the medium shows that it is not.

When I install a program, it recommends me to do chmod 4555. Okay, i know about values if I just use three numbers. For example  chmod 555 test-file   will give  -r-xr-xr-x   4 for write, 2 for read and 1 for execute. But, when I do this:  chmod 4555 test-file   it gives me  -r-sr-xr-x   So, x changed to s. What's that mean?

How do I burn the latest 12.10 790 MB ISO to a CD?  My burning software says insert a disk but 700 MB CD's are too small. I tried a DVD and that didn't work either.

Does anyone know an easy way to write files to a DVD from the command line. I've found a program that does it for CDs, and another that writes .ISO images to DVD.  I want to use it to write files to a backup DVD overnight.

I upgraded from Windows 7 to Windows 10 recently, and am looking to burn some .iso files. In Windows 7, there was a default program that I could use. I have dug around a bit, but cannot find one in Windows 10 so far. Although, a bunch of search functionality seems to be disabled on my machine, so I may just be searching incorrectly.  Is there a disc image burning program bundled in Windows 10 like there was in Windows 7?  Image of what I see:

I've got a DVD that I've burnt from an MSDN ISO. I'm not entirely sure if its Windows 7 64bit or 32bit.   How can I be sure?

I can't see that - &lt;---|---&gt; + indicator in my viewfinder (I can see it only in manual mode and it used to be everywhere). I went through the whole menu and didn't find anything that may be causing it.   Any ideas?  EDIT: when I cover the lens that indicator shows up. But there's no use for this behavior :)

I have copied an entire DVD to my PC but when I try to play it in VLC it does not play perfectly and sticks every time. When it is played directly i.e. from the disc, it is played perfectly but in Windows Media Player. Does VLC not support original DVDs and .VOB files? Is there any way to play .VOB video files in VLC?

I'm picking up a used Xbox 360. It isn't expensive and the seller has agreed to let me try it out first. To test it out, here's some things I'm trying to get answered:   Is it banned from Xbox Live? Is the DVD drive in good condition?   How do I check whether this particular Xbox has been banned?  Are there any other things that I should check?

To stupid people, like me, you would have thought overwriting each bit on a disk would render the data completely unrecoverable.  Why do disk wiping tools have the option for multiple passes, i.e. 3 or 5, even 7 and different methods?  Surely the first pass does the job?  My question - Is it just down to pure paranoia or should I be using multiple passes when wiping disks... and why?

@enzotib mentioned the following command  sudo mount -o remount,rw /cdrom   Does this imply I can mount a CD or DVD in rw mode and use like a (real) filesystem? Does this work with the popular ISO-9660 filesystem, which is read-only by design? Will this create a multsession CD with one session per change (or per mount)?  Would this work (differently) on a ISO image file on a read/write filesystem?

I usually use the very nice and simple dvdbackup program to rip and backup my .   However some of my DVDs have a few scratches and my DVD drive has some trouble reading a few sectors. So, is there a tool similar to cdparanoia, but for DVDs?

I didn't had this problem before, recently I bought a SSD and installed Windows 7 x64 on it,  and now the DVD sometimes spins without reason, it has no CD in it (this makes a bit of a lag).  EDIT:  it usually spins when I start windows explorer, or some other action that probably involves exploring windows folders (starting winamp also could spin it)  saving a file (in ms word ctrl+s) can also spin it

In Linux, what does the d mean in the first position of drwxr-xr-x?  And what are all of the possible letters that could be there, and what do they mean?  I'm trying to learn more about the Linux file permissions system, and I'd like to see a list of the character meanings for the first slot.

Is there a way/tool to determine the date and time when a disc has been written/burned with high certainty? This is about data forensics and should be a solid proof. I already tried IsoBuster, but it didn't show me the date/time at which the track has been written.
