the Philips CDRW2412 drive will no longer be shown on the MY Computer Hard Disk Drive and would not be recognize by the system nor be listed under my Hard Drive Device manager
It won't be listed under your hard disk drive. It should be listed under DVD/CD drives, like the 3rd or 4th + symbol down under device manager.
When you have it working, find it in device manager, right click on it and click on uninstall. Restart your computer, and Windows should automatically reinstal it.
If this doesn't work, have you installed any different/new programs when it started doing this?
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
