DVD/CD unit is not operating propeerly

[4George]

Hi

Recently this unit is not recognising pre-recorded or formatted discs which
it previously had recognised. I have a HP laptrop and the drive is a
matshita DVD-RAM UJ-850S ATA.

I have tried deleting and reinstalling the driver with no success. In one
of the forums it is suggested that the 'UpperFilters" and "LowerFilters" in
the HKEY registry be deleted but I am not sure about doing this without
someone in the know gives it their OK.

Can you help please.

The Upper/Lower filters fix is for when the optical drive is not showing at
all in Device Manager.

Unfortunately, in your case, it appears to be showing..... it's the disks
themselves that are not being read and I think it's more likely that the
drive has failed or is failing. Is this problem both with DVDs AND CDs or
with only one format?

George,
The upper/lower filters thing is an MSFT recommendation.

Before doing that, try your "unreadable" discs on another PC and see if they
are Ok.

Ok i have a problem
Last night i was riping a cd onto media player and after i was done the cd
drive on my laptop wouldnt open. After i went to school and it shut down it
open and i put a new cd in their. Now the problem is the cd drive isnt
recognizing that there is a cd in the drive. I go to rip in my media player
and it says you have to have a cd in there, when there is one in there. What
happened?
I have a toshiba satellite P200D/P205D Series, a few weeks old

First thing to try is a reboot.
