Destroying CDR data

[rh71]

I know this will be one of the strangest questions you'll see on here, but here goes. I would rather not go into the details as to why I need to do it... /forum/wink.gif

Anyway, is there a way to corrupt/destroy the data already recorded onto a CDR without physically/cosmetically ruining the layer? I have access to the CDR and my own burner. I also use Easy CD Creator. The CDR is not a rewritable disc.

Let's hear even the obvious ones... I'm talking magnets (is that possible) and whatever else you can come up with! Thanks for suggestions. I need this done.

Personally if you need to get rid of the disk then FOLD IT IN HALF. /forum/biggrin.gif but as for "altering" the disk WITHOUT deforming it good luck as you stated it CDR not CDRW (your burner WILL NOT let you overwrite it). if you were VERY careful you might beable to use a torch and reheat the disk to the point that it corrupts the data (but if you hold the torch to close/to long you will damage it cosmeticaly.

If I'm not mistaken you can erase data from a CDR and it will show as used space. However you cannot rewrite to the CD once it is closed out. Drop me an Email if you would like me to check this out futher. I have Easy CD Creator 4. Good Luck. RJ

Well, yes, the CDR has been closed out. And when I try to import session with the CDR in the CDRW Drive, it will spit it out and ask for a disk with sufficient space.

RJR, can you please look into how I can erase the data and have it show up as used space? I have Easy CD Creator Deluxe 3.5c.
Thanks!

How about just coping what you need off of that CDR onto a new CDR that looks identical?

The only way to do it once the disk is closed is actual physical dammage to the disk, like mntsnow said by selectively burning it, or otherwise with a scratch. Though the chance of not damaging the other data is risky. If there is some other data on the disk that you want to keep, maybe the best thing to do would be to reburn it to another disk and then snap the one you have at the moment.

Hmmm you could pull apart your CDR and selectively blast the CD with the write laser. Wear dark goggles though /forum/smile.gif

Strong UV might degrade the plastic to the point of making data unreadable. I think this was a problem with early audio CDs when they came out, which used a plastic which wasn't resistant. Excessive heat could also warp the foil inside the CD, but the chances of doing that without visibly damaging the disc are slim.
Alternately that stuff used to burn PCBs, or a solvent like acetone or Liquid Paper thinners would probably give it a nice attractive matt finish.

Are you in the industrial sabotage field, btw? /forum/wink.gif

Microwave it? Run an electrical charge through it? Dunno... I don't know what either would do to the disk, but... Tape it to one of those metal detectors at the courthouse for a day... Of course you'd have a hard time explaining to the cops there WHY you wanted to do that...

rh71. I thought I let my mouth overload my ****. Not so. "Note: Only CD-RW drives can read, write, and erase data to CD-RW discs. “Deleting” files from a CD-R disc makes the files invisible to the file system but does not free up any space on the disc."
The above quote came from the help section Direct CD. If you need more help on this
Email Me. RJ

Hehe, sabatoge field... well, sorta. /forum/wink.gif Or maybe I want to see how creative people at this forum can be. /forum/smile.gif

Anyway, yeah, I don't care if the CDR can't be readable anymore. I just don't want it to look like it was physically tampered with. So selective data, all the data, I don't care. Would rubbing alcohol do physical damage?
