How Do I Get D Drive Back on Computer?

by James B. Jones

On rare occasions after a computer crashes, you will find that your D: drive, which is most commonly associated with a CD drive, cannot be found inside of your Windows operating system. While this can be cause for alarm, know that remedying this issue is a relatively simple process that only takes a few minutes.

Restoring D: Drive

Step 1

Open your \"Start\" menu and click the \"Run...\" button. In Windows Vista, this option can be found under the \"Accessories\" tab in the \"All Programs\" menu listing.

Step 2

Type \"regedit\" into the \"Run...\" box and press the \"Enter\" key, which brings up a new window titled \"Registry Editor.\"

Step 3

Locate the \"HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class\\{4D36E965-E325-11CE-BFC1-08002BE10318}\" registry folder in the left-hand sidebar.

Step 4

Delete both the \"UpperFilters\" and \"LowerFilters\" options.

Exit out of the Registry Editor and restart your computer. Upon reboot, open \"My Computer\" to see if the process has worked.


  • Some may not see an \"UpperFilters\" option. If this is not there, proceed with the \"LowerFilters\" deletion.
  • If all your drives are still registering but with different letters, you can manually change the letter of your drive through your Computer Management window.
