Missing DVD ROM Drives

  Woodmouse 18 17:17 19 Nov 2006

Yes - I admit I have been fiddling - but now I seemed to have lost both my DVD ROM Drives. On boot-up, Windows says it has detected them, but when I call up Windows Exporer, they are not shown. I have removed both drives and re-booted. Then inserted them one at a time. Still no joy. Any ideas please.

Missing cd/dvd drives can be normally associated with the removal of burning software such as Nero/Roxio etc.

Restore Missing CD/Dvd Drives

Missing cd/dvd drive
If it is showing an error code, 10, 39, etc., delete the drive.

Then follow these directions for clearing the Upper/Lower Filters: (might want to print this out)

1. Click on Start --> Run --> and type in 'regedit' followed by the enter key
2. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or
3. clicking the "+" next to it.)
4. Expand the "SYSTEM" Key
5. Expand the "CurrentControlSet" Key
6. Expand the "Control" Key
7. Expand the "Class" Key
8. Please look for a key containing the following string of letter and numbers:
9. High light this key by left clicking once on it
10. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these please delete them by right clicking on them and choosing "delete"
11. Please exit the registry by clicking on the "X" in the top right hand corner of the screen

If you have any error codes,please post them.

If you can still see them listed in Device Manager whilst in Safe Mode then it is very likely to be loosely fitted (or faulty) connection IDE cables.

You should also have one drive as Master and the other as Slave, otherwise only one is recognised.

As you state they are both ROM drives I'm assuming that skidzy's advice, normally appropriate, won't/may not apply unless you have a third drive (rewriter).

Hi Stu

if Woodhouse can list any error codes it would help enormously.

As you have said its possible it is listed in Device Manager but missing from My Computer,then i am assuming the registry has been corrupted,possibly one or two burning software apps have caused this.

One of my systems developed exactly the same symtoms around 2 years ago and that only had a cd-rw/dvd rom drive,and the only way to sort the mess was by clearing the upper and lower filters or of course a restore to factory settings.This link will help with any error codes.

Obviously checking all connections and maybe swapping IDE cables should be the first port of call as Stuartli has pointed out.
