Deleting CD-R Data

CD-R is a "recordable once" media meaning that data once written on the disc it will remain there and cannot be overwritten.  Even if you write multi-session the data from previous session remains.

The only way to delete the data is destroying the CD.

Our Friend r right ! CD-R drives can not be erased actually ! but u can delete them virtually ! ;) it means that it doesnt free any space but deletes virtually the files on the disc, for example u can have a blank cd with 100 MB cap ! and one 200 MB ! try Nero and start multi-session disk and go on ! remember just multi session disc can be erased virtually ! u should not finalize the CD ;)

Hi...

CD-R are write once and read many time cd's.

You one burn the cd-r then you cann't delete the data from the cd-r

Second, Option is Using CD-RW i.e write many time and read many time..

Everyone else said this... so i figured i would to..

CD-R can only be writen to once. (well, once in the same physical location on the disk).  I have never heard of what fifthelement80 said.  Since CD-Rs are so cheap, just trash it and try again.

Start a multi session disk in nero and burn some files on it, then select "new" and choose "continue multi session" and select some files in the disk and press delete !
and burn ;)

Leave the CD on or near a sunny window.  Over time they will go brown an be useless. (credit goes to someone else who will remain nameless) aaaarhhhhh!!!!!

Take them outside.  Data side down and ice skate across a concrete surface with them.

I'm not telling Olliedv to use his old CDs ! I'm just talking about possibilities ! I agree that old CDs r useless and we should take them outside :p
Regards

what a multisession does is add stuff to a CD-R. Say you want to burn 2 Megs today. You can do that. Then you can add another 5 Megs the next session. Unless you "finalize" is, you can keep on adding stuff until the CD is full. If you delete stuff, it will still be physically there, but the master registry will indicate that you deleted it. It will remain physically burned into the CD, but the REader will just ignore that section that you "deleted".

No.

actually, i think he is talking about somthing totality different.

"i am on windows xp and have messed up several cd-r discs "

I think he means that he got a buffer underrun, or somthing that caused the disc to fail.  At this point, unless his burning program finalizes it, the cd is completly useless and is trash.  I know the newer version of the buring software will finilize where it died so some data might be readable.  This was not the case a few years ago.

It's pretty doubtful that the problem was a buffer underrun. Today's Burners come with built-in hardware buffer underrun protection.

Good point Spongey, but Oliedv hasn't specified the model, age, write speed, etc of the CD-RW Drive.  Even with a standard 2MB buffer, some CD-RW's even a year old can suffer buffer underruns dependent on the type of data being copied, and whether it is a CD to CD-R copy or via the hard drive.

Oliedv.  My advice is to disable the CD Burning Servive in XP and use another software application such as Nero, Easy CD Creator from Roxio, or WinOnCD also now by Roxio.

Anybody who has recently bought a CD-RW drive, and who already had their own software, will have a surplus version of one of these.  Although these bundled CD's are often the "Lite" versions of the full-blown product, they all will test the read/write speeds of your CD and CD-RW drives, and store the settings as the theoretical maximums for a variety of data/medium types.

Thereafter, it is a case of experimenting by cutting back on your selected write speed in combination with enabling buffer underrun protection via the software's options until you get some indication of a reliable write speed you can use consistently.

While experimenting, create multisession CD-R's and you aren't wasting a CD-R each time until you get it right.

Most, if not all, of the bundled software versions have the option to first write the data to the hard drive, and then write to CD from there.  It is faster and more reliable, especially where data CD's such as software titles can cause the source CD to hunt for data or where you have small scratches or fingerprints on the source CD.

If you are copying music, I recommend first "ripping" the tracks from a source CD to your hard drive as .wav or .mp3 files, and then creating a custom "project" whereby you select the saved files for inclusion.  This may obviously be in breach of anti piracy legislation, but that's a matter for you to recognise and justify.

If you need advice on how to disable the CD Burning Service in Windows XP just ask.

Great answer................................................

i dont know why i didnt think of that................

lol u dont have to be so sarcastic to him, lol!
