- Blu-ray support
- added CD raw reading and majority algorithm
- C2 scanning support for CD media
- changed treatment of CRC failures: old behaviour was to
store a defective sector marker; now the actual sector
contents are written to the image file.
- Using the CDROM_SEND_PACKET ioctl() will hang parallel
SCSI adapters. Added tests to determine the SCSI bus type,
and switch to the SG_IO ioctl() when in doubt. [Linux]
- fixed and documented -n command line options for RS02.

Optical media (CD, DVD, BD) 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/BD 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 does not
|
|
depend on the file system of the medium. The maximum error correction
|
|
capacity is user-selectable.
