Evening all,

I've seen a number of cases recently where the disc drive ceases to function (mainly in laptops for some reason), usually evident by the icon no longer being displayed within My Computer.

Seems to be when someone either updates or installs a Symantec (mostly Norton 360) product.

To resolve it?

Open up the Windows Registry Editor:

HKEY_LOCAL_MACHINE
>SYSTEM
>>CurrentControlSet
>>>Control
>>>>Class

Select the entry entitled: (May be easier to look for the 965, usually this entry is about tenth from the top)
{4D36E965-E325-11CE-BFC1-08002BE10318}

If you open up this entry you'll see an item named 'Upper Filters'; if you select and delete this then restart you machine. Quite often you may see an item named 'LowerFilters' - this should also be deleted if you have it.

Once you have deleted both (if you have both) and restarted, you should find that your drive works as per normal.

Hope this helps,

Darren
