Plextor Plexwriter Another Question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



	Thank you.  I have also found that I don't have /dev/sgx
devices installed and that is most likely the biggest problem.

	I will have to give cdparanoia a try but first I must get
a valid SCSI device since cdrecord and cdda2wav as well as
cdparanoia all want to see a SCSI adapter.

	It's all so close and still just out of reach.

	I suspect that when it is working, I will be able to rip
tracks from audio disks that will then play correctly as there
appears to be nothing at all wrong with the existing CDROM drive
that is in the system.  When it is reading data CDROM's, it hums
right along and does what it should.
