[QUOTE=mciahel;2151703]Hi,This error might mean, Kprobe has a problem there. It does not necessarily mean, the disc is bad.
Please note, Kprobe is 4 years old and was designed to work with Liteon drives of that era.
Perform a Transfer rate test using CD/DVD Speed (preferably with your worst drive). The read curve should be smooth.
You are right about how old Kprobe is.
Which tool you suggest me to perform disc quality checks?
