a very good professional level free alternative to ISO buster and help recovering back scratched DVD's with priceless photos or documents inside..
hmmm, don't think so:http://dvdisaster.sourceforge.net/en/
Common misunderstandings about dvdisaster:
dvdisaster can not make defective media readable again. Contents of a defective medium can not be recovered without the error correction data.
From what I've seen it is a FREEWARE alternative to Arrowkey/Infinadyne Accuburn-R a Commercial program that makes sure that data is properly written to optical media.http://www.infinadyn...accuburn-r.html
Actually it appears that dvdisaster works more with redundant checks in a way similar to .par data files do with respect with .rar (or similar) archives.http://dvdisaster.so...en/index30.html
Limitations of using dvdisaster:
Error correction data must be created before the medium fails, preferably at the same time the medium is written.
Error correction data requires additional storage space either on the protected medium or by using additional media. Using the standard settings the additional storage space amounts to 15% of the original data size (approx. 700MB for a full 4.7GB DVD).
no guaranteed protection against data loss.
The advantage that Accuburn-R sports is the fact that data correction is done WHILE writing on the optical media, if needed re-writing the parts appearing to be defective.
As I see it, the 15% more space occupied by dvdisaster, but I recall using Accuburn-R with CD's at work and the increased amount of space taken was in the same order of magnitude is a big trade-off, is only worth it for "real" long-term backups, which should be ANYWAY be kept with great care and avoiding scratches.
However, being "normal" burning apps, expecially in combination with particular brands/manufacturers of media, more or less "untrustworthy", unless you manually verify with another program like CDCHECK the actual readability of the burmed CD, having a safer FREEWARE app is a good thing.
There is also a positive "side-effect" use for it when trying recovering a "normal" scratched CD by means of manually polishing the surface with Brasso or similar compounds, the "mapping" of the unreadable sectors makes it easier to understand (roughly) where more polishing is needed:http://www.msfn.org/..._CD_t56005.html
