dvdisaster uses the optical drive interface by default. This may cause
system failures on some ancient SCSI controllers. Try using the generic
SCSI driver with the option \-\-driver=sg in such cases.
Selects between the sg (SG_IO) driver (default setting) and the
older cdrom (CDROM_SEND_PACKET) driver for accessing the optical drives.
Both drivers should work equally well; however the cdrom driver is known
to cause system failures on some ancient SCSI controllers.
The older cdrom driver was the default upto and including dvdisaster 0.72.x;
if the now pre-selected sg driver changes something to the worse for you
please switch back to the older driver using \-\-driver=cdrom.

The drive firmware usually retries unreadable sectors a few times before
giving up and returning a read error. It is more efficient to set this to 0 or 1
and manage read attempts through the --read-attempts parameter. Most drives ignore
this setting anyways. Use -1 to leave the drive at its default setting.

However some drives can only read defective sectors using mode 21, skipping
the last stage of the internal error correction and returning
