Disc errors when booting latest TC release from a CD

coreplayer2:
I get these errors whenever booting tc with a cd/dvd in the drive.  same results but not consistently with commercial disks or cdr.  am going to revisit this issue asap

Ru and Rich,

i have not actually tried burning TCL again just yet. But i will give it a go soon because
i don't like seeing those errors.

Ru was saying that his CD recording tool always defaults into the max speed
that a CD RW disc will support. Mine is similar and i am not sure if that speed
can be altered.

I will have to burn the CD from the Linux desktop and issue the command that
Ru has mentioned in this thread.

It looks pretty likely that my situation is similar to others in this thread...it's a badly
burned CDRW disc.

Having said this, i have been burning distros for 8 years and this has never happened
before ever. Even with this same hardware, but  ofcourse, different media discs each time.

Just a note on this kind of topic that i am sure you are all aware of. Cheap blank CD discs can loose
the optical burn for no reason. It tends to happen after leaving the discs in darkness for a few weeks. They
gradually loose the optical burn and eventually fail to run. Externally the disc looks perfect without any
scratches or such like. You can't guess it's a faulty disc....you just eventually realize. This can be
tricky when you have already been successfully using the said "burned disc" for weeks.

Nonsense. CDs are not sensitive to the presence or absence of light. Temperature extremes might
cause you problems. Heat generated by the LASER beam in your CD drive changes the reflectivity
in the disc by altering the color at the points you are writing to. So if a blank disc has all zeros, the
LASER heats the points where you want ones. CDRWs are the same except power levels, heating,
and cooling time are more critical. It is because of this last point that CDRWs also have a minimum
write speed. I have some 24x CDRWs, the minimum write speed listed on the package is 16x.

cast-fish:
in that case Rich, is it possible that a CDr disc can have scratches
that are not visible by the naked eye, but scratches that can make the disc optically non readable?

During last 20 years I have never seen CD's degrading in time, but have seen faulty, unrealible discs due to faulty CD writers having very short lifetime.
