I'm using Ubuntu 13.04. I want to take an ISO copy of XP installation CD but when I insert CD it's seen as empty CD. Is there any way to access the content of CD?
From what you have posted, this sounds more like a hardware issue than a software one. It is likely that the drive isn't reading the disc because either the CD is dirty/scratched, the lens in the drive is dirty and/or the drive is near the end of its life. For the drive, you would tend to first notice issues with copied and/or scratched discs.
Another possibility for a copied disc is that there was an error when burning (or it simply wasn't formatted correctly).
Either way, I would suggest trying the disc in another drive. If it reads ok, at least you can rule out that it is completely corrupted.
Otherwise you could try:
- Clean the disc - ideally with something made of soft cotton.
- Clean the drive lens - ideally gently with a soft cotton bud and iso-propyl alcohol, although this may require dismantling the drive. You can get lens cleaning kits, though often they aren't that effective.
depending to the comments above:
On automounter you won´t see errors. Try to mount it manually on shell.
The command on ubuntu should be
sudo mount /dev/yourdevice /your/destination
And see if it prints some errors.
But: If dd was not able to find anything your cd, it is really unreadable, so they are too many scratches on it. Try to clean it up and test it again. If it doesn´t, try to download Windows XP related to your version on CD. So, your key should work on this download. You can also try ddrescue. In this case, because CD´s are only readable, you may use ddrescue direct (remember first using dd for nearly broken hdd´s and then ddrescue on the mirrored file(s)).
