probelm

anybody have a suggestion or two

it could be an issue with the registry upper and lower filters.

First go to device manager and right click and uninstall both the drives.
then follow these steps to delete the upper and lower filters.

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-
BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone

MANU44

i followed what you suggested

and reboot everything appeared in devive manager with no exclamation
