Is it possible to write protect a CD-RW?

[kazzer]

Is this possible?......


Thanks!

There were some application that created a Copy protected CD. I used to have a copy of such tool. But the newer versions of Nero, Roxio and other burning applications are now able to copy them.



So the answer is: Yes there are.

But they are not useful anymore.

I just found the link for the Audio CDR copy protection, http://www.burnarchive.com/CCD-Lock/ It's in german by the page could be translated using http://babelfish.altavista.com.

Also you could take a look at CopyKiller, a copy protection (based on defective sectors). At http://www.webstylerzone.de/CopyKiller/En/index.htm

It looks like no one is paying attention to the question here. Kazzer asked if it's possible to WRITE protect, not copy protect, a CDRW. I can see where that would be useful, if it's reversible, such as a backup that you don't want someone to overburn, but, practically, why don't you just use a finalized CDR? Not multi-session. Disks are cheap enough, and burners fast enough that it's probably quicker to do a new backup, at 48 or 52X, than a CDRW, incremental or differential, at 12 or maybe 24X. I backup what's important on my C drive to a couple CDRs. Everything else is on another partition, if not another drive entirely, so barring catastrophy, very little would be lost, and most of that downloadable, as the original was.

You are spot on gmtov!...Finally someone with an informative answer!

The thing is I use CDRW's to incrementally backup data on a weekly basis, and also to store MP3. I just thought that instead of making 'backups of backups', so to speak, it would be very handy if one could use a tool to write protect the CDRW. But it looks like i will just resort to backing up these CDRWs on CDRs. Thanks for your reply!

Kazzer,
I'm a little confused as to incremental backup to CDRW. Now, we write to blocks and sectors and allocation units and clusters. If we have data that changes in content, but not in quantity, I can see re-writing, because the old data would be overburned (I should say overwritten), but if, say, a database, or a folder of MP3s is being updated, where would a CDRW write the new data, or write the new, entire database?
Does it just fill out the allocation unit, or cluster, and go to the end of the previous burn, and continue there? A HDD will drop data whereever the next available block is, and record such. Does a CDRW do the same?
I know access times are meaningless to us Hyumonns, but the benchmarkers will tell you you're wasting valuable waiting time.
Regardless, I think, still, I'd just use a CD-R, and pitch, or keep the old one for reference. They don't really take up much room, 'specially if you stack em on an old spindle.
Thanks for the compliment. Some of these forum posts remind me of my daughter's chat way back when, when they sent rat now, just to make themselves heard, and no 2 people were on the same page.
Too many people assume what they look at is what they want to see.
Taint necessarily so.

Sorry George, i cant help you with your queries regarding incremental backup on CDRW

Maybe a more proficient user can help you and will post.......
