About the changes on the wiki

Hello. I appreciate your great interest and I agree with some of your requests, especially on clarity. Do not use the main page for experience any changes, because it is a reference page for the entire community. You have to follow a path, discuss the changes, what to change and how to change, apply a "template" to signal to the whole community of possible changes etc. .. Also, any changes must be described on the main page, and in the event of major changes effettualri step by step. Other users can't understand all the changes made. This procedure may seem slow, but considering that it is not a personal wiki, but Community. good weekend.Veleno (talk) 11:00, 27 July 2013 (UTC)

It is well understood that i need approval. Especially since i am an interested party in the field of optical media. The proposed changes are listed at the talk page. What kind of approval do i have to wait for ?
How do i apply a "template" ? (I guess it is a way to expose an implemented proposal for approval.)
Your proposed changes are wide margin, reflecting a possible reorganization of the entire page. You rightly point out that there are gaps and that it can improve the whole. I answered you on the talk. I think you can from your proposal to amend the best across the page, for example, by combining the relative sections of CD and DVD in one section. does not exist a body that approves, you expect a few days, if no one dissenting opinions, you can operate to change. What you propose is not a small change, but I think a broader change that, in my opinion, it should be well organized. that's all. I apply a template that links to the discussion. ;) Veleno (talk) 11:37, 27 July 2013 (UTC)

Test area


Learning the name of your optical drive

(replacing section 3)

For the remainder of this section the name of your recording device is assumed to be /dev/cdrw.

Check this by

$ wodim dev=/dev/cdrw -checkdrive

which should report "Vendor_info" and "Identification" of the drive. The next guess could be /dev/sr0.

If no drive is found, check whether any /dev/sr* exist and whether they offer rw-permission to you or your group. If no /dev/sr* exists then try

$ modprobe sr_mod

Erasing CD-RW and DVD-RW

(replacing sections 4 and 19)

Used CD-RW media need to be erased before you can write over the previously recorded data. This is done by

 $ wodim -v dev=/dev/cdrw blank=fast

Unformatted DVD-RW media need the same treatment before re-use. But fast blanking deprives them of the capability for multi-session and recording of streams of unpredicted length. So one should apply

 $ dvd+rw-format -blank=full /dev/cdrw

Alternative commands are

 $ cdrecord -v dev=/dev/cdrw blank=all
 $ cdrskin -v dev=/dev/cdrw blank=all
 $ xorriso -outdev /dev/cdrw -blank as_needed

Formatted DVD-RW media can be overwritten without such erasure. So consider to apply once in their life time

 $ dvd+rw-format -force /dev/cdrw

dvd+rw-format is part of package dvd+rw-tools. Alternative commands are

 $ cdrskin -v dev=/dev/cdrw blank=format_overwrite
 $ xorriso -outdev /dev/cdrw -format as_needed

All other media are either write-once (CD-R, DVD-R, DVD+R, BD-R) or are overwritable without the need for erasing (DVD-RAM, DVD+RW, BD-RE).
