Can some one tell me how an actual CDRW overwrites information?
Hi all....
My question is how does a CDRW overwrite information when saving data?
The scenario is that I use INCD (packet writing software) and have a simple batch file that will backup and overwrite data onto my preformated CDRW's.
Now someone has told me when using CDRW's it does not really overwrite. (which I'm starting to believe due to Nero's 2 options to Quick Erase and Full Erase CDRW's) This same guy told me CDRW's are not the best media to backup onto and that I should use HDDs. Well with data less than 800MB burnt daily to 7xCDRW's at $1-$2 each compared to multiple removable/portable $100 80GB Hdds the cost, portability and physical space is definately an issue.
I know that when you use a CDR you can multi session the disk and eventually max out the storage space, but on a CDRW, if you are overwriting the same file/folder on the CDRW, will it use the same storage space the CDRW has already assigned to that file/folder? Or will it take up a more space on a CD and wipe the previous data?
Can someone tell me how they really work when overwriting data onto CDRW's with and without INCD????
Many Thanx

Hi Jvuz
Thanks for coming back.
Well its for home, (unless I bring my home pc to work, then it could be a company !) but some people at my work were curious also.....by the way what difference does it make? pardon my ignorance.......

Hmmmmmmmm...........
I see.
You're right about the tape drives and tapes, $300-$600 for drives and $40-$120 for tapes.
As for the problems with CDRW's I've haven't had any problems beside Speed issues with discs/drives mismatch, They seem better than disks and zip drives (the very common click of death from iomega, thank you very much!)
Well that still leaves my question unanswered (If CDRW's really overwrite data or do they write elsewhere on the CD and hide/wipe previous data)
Anyway, thanx for your input, I might leave the question open for a few days and see if anything else comes in, but if not, then 50 big ones are coming your way!
Cheers

When i say bonds between hydrogen and carbon atoms, i meant just between carbons, my mind was on polymers for some strange reason

Many Thanx to Jvuz & Andyalder
And a big thanx to Phil Upson (although I might need to take an asprin.....too many words for a friday morning... and also pick up my masters degree in CDR/RW technology!)
All replies were extremly helpful and I will try to distribute points accordingly. (sorry if it doesn't work!) Thankyou all.
