  Thanks - you saved my bacon. I had a USB mass storage device that wasn't showing in Explorer. Didn't realise I had to format & register it here first ... (assumed it had arrived already formatted).

  In the installation of a NEW primary hard drive, somehow it was assigned 'E' instead of 'C'.
  
  Using the procedure to reassign it to 'C' does not work.
  
  The procedure does NOT allow reassigning the boot drive letter.
  
  Anyone have any ideas?

  Forgot exactly where I googled this from, but it worked for me in the same circumstances:
  
  This procedure swaps drive letters for drives C and D. If you do not need to swap drive letters, simply name the DosDeviceletter: value to any new drive letter not in use.
  1. Make a full system backup of the computer and system state.
  
  2. Log on as an Administrator.
  
  3. Start Regedt32.exe.
  
  4. Go to the HKEY_LOCAL_MACHINESYSTEMMountedDevices key.
  
  5. Click MountedDevices. On the Security menu, click Permissions. Check to make sure Administrators have full control. Change this back when you are finished with these steps.
  
  6. Quit Regedt32 and start Regedit.exe Go to the HKEY_LOCAL_MACHINESYSTEMMountedDevices key.
  
  7. Find the drive letter you want to change to (new). Look for "DosDevicesC:".
  
  8. Right-click DosDevicesC:, and then click Rename.
  
  9. Rename it to an unused drive letter "DosDevicesZ:". (This will free up drive letter C: to be used later.)
  
  10. Find the drive letter you want changed. Look for "DosDevicesD:".
  
  11. Right-click DosDevicesD:, and then click Rename.
  
  12. Rename it to the appropriate (new) drive letter "DosDevicesC:".
  
  13. Click the value for DosDevicesZ:, click Rename, and name it back to "DosDevicesD:".
  
  14. Quit Regedit and start Regedt32.
  
  15. Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
  
  16. Restart the computer.

  i have an XP machine. it has had an external hard drive connected that has all my music loaded on. it has worked fine for a few years. music is set up through media player, i have also built playlists, etc. in My Computer, this external has always been "L drive". all of the sudden it doesnt show up in my computer, i cant access music in media player- no paths. i tried plugging it into other USB ports with still no recognizing of the drive. i have plugged mp3 players into these USB ports, and they do get recognized. i plugged a different external hard drive into the USB ports, and it doesnt show up either. does my computer now have a prob with external hard drives? very strange- HELP

  I want to switch the drive letter between E and F. Referring to your instruction, I changed the drive E to X successfully. However, I can't find out the E in the drop down list when I tried to change the drive F to E. I also tried to reboot the company and do it again. However, I'm still unable to get letter of E in the drop down list. What should I do in this situation?
