Free cd dvd duplicator software for mac

Requirements: Mac OS X 10.3.3 or later.

CD and DVD media keep their data only for a finite time (typically for many years). After that time, data loss develops slowly with read errors growing from the outer media region towards the inside.
dvdisaster stores data on CD/DVD (supported media) in a way that it is fully recoverable even after some read errors have developed. This enables you to rescue the complete data to a new medium.
Data loss is prevented by using error correcting codes. Error correction data is either added to the medium or kept in separate error correction files. dvdisaster works at the image level so that the recovery will not depend on the file system of the medium. The maximum error correction capacity is user-selectable.
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.
- Such functions are outside the scope of dvdisasters internal design and goals.

- fixed rare crash while linear reading due to a race condition
- by improper ClearCrcCache() usage.
- fixed bogus dead sector warning in the linear reader
- after encountering unreadable sectors
- made adaptive reading pursue raw reading more aggressively;
- effectively trading in place re-reads for seeks over
- the medium.
- help output for --defective-dump was complete nonsense. Fixed.
- detection of read errors at the end of track at once disks
- would sometimes cut off too many sectors when doing multiple
- reading passes and a carefully crafted number of extra read

ISOlator 2.0 brings you a convenient desktop utility which is useful in case you want another copy of, but don't want to download it again. Got a CD that needs to be in the computer to play your game, but you don't want to risk scratching the original? Need to make backups to protect against kids? ISOlator is for you. ISOlator takes a CD, DVD, or other mounted volume and makes an ISO out of it. The ISO can then be burned to CD, stored on your backup disk (you DO backup, right?), or put to use however you like. ISOlator uses the Unix command line program 'dd' to make the copies, and is very easy to use, just drag and drop!
