What happened to my cd-rom driver and why is it disabled?

I have been using the Sony DVD drive for quite some time now, but when
I went to install a new program from a CD, the drive did not respond,
and it doesn't show in the list of drives. When I go into the device
manager, the device is shown with a little yellow spot, and the message
box says the driver service is disabled. What driver service is this,
and how do I enable it?

I looked at the driver details, and cdrom.sys is shown with an icon
containing a green checkmark. The device is the SONY DVD RW DRU-800A
ATA device. There is a second driver file listed in the driver
details: PxHlpa64.sys. This has a copywrite from Sonic Solutions, and
seems to be part of movie maker, which is a microsoft application under
Vista Ultimate. I have not ever used movie maker, as far as I know,
though I was trying to see what photo software I had, and I use the
Windows photo viewer and editor, whatever it is named.

Peter Foldes had this solution for the same problem elsewhere

Last week another poster had the same issue concerning Code 10 that affected
his DVD-RW and the following
below fixed it for him.


The below has to be followed in the order as posted

(1) Read the following and implement

(2) Now do the following fix as written in the following MS KB concerning
your Lower and Upper filters. It works also on Vista

John,

I think step (2) fixed the problem. It turns out that the second driver
file, PxHlpa64.sys, was showing in the lower filter key. When I deleted
that key, and restarted the computer, the CDROM.sys driver was showing as
good to go. Thanks for the help.
