Sometimes CD or DVD drive may simply "disappear" or suddenly vanish from your computer under Windows XP, despite the fact it had been previously installed. Perform the following simple steps to recover your lost drive.

NOTE: We assume that the drives for missing drive are intact and other possibility has been tried.

1. Open a notepad.
2. Paste the following code –

   Option Explicit
   On Error Resume Next

   Dim WshShell, Message

   Set WshShell = WScript.CreateObject("WScript.Shell") WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\UpperFilters"
   WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\LowerFilters"
   WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_2K\"
   WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdralw2k\"
   WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf\"
   WshShell.RegDelete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr\"
   Set WshShell = Nothing Message = "Your CD/DVD-ROM drives should now appear in Windows Explorer." & vbCR
   Message = Message & "You may need to reboot your computer to see the change." MsgBox Message, 4096,"Finished!"

3. Save this file with .vbs extension. For e.g. cd_dvd.vbs
4. Now simply double click the file or open it with command prompt.
5. Finally your CD/DVD ROM should reappear. If it doesn’t then reboot the machine.
