I have scripted DriveIcon.bat to create a custom drive icon for any drive letter that you specify.

The syntax for using DriveIcon.bat is:

DriveIcon DriveLetter DriveIconPathIndex DriveLabel


DriveLetter        is the drive letter of the fixed or removable drive.                              DriveIconPathIndex is a quoted string that contains the path to the file that contains the icon, a comma (,),                                                  and the icon index, starting with 0. The second row in column 1 is 1, the third row in column 1 is 2, etc.....                              DriveLabel         is the drive label.
NOTE: If the drive is mounted, the new icon will take immediate effect. If the drive is not mounted, a restart is required.

DriveIcon.bat contains:

                              @echo off                              if \{%3\}==\{\} @echo DriveIcon DriveLetter DriveIconPathIndex DriveLabel&goto :EOF                              setlocal                              set wrk=%1                              set wrk=%wrk:"=%                              set drv=%wrk:~0,1%                              set icon=%2                              set file=%icon:"=%                              if "%file%" EQU "%icon%" @echo DriveIcon DriveLetter DriveIconPathIndex DriveLabel - "DriveIconPath,Index" required.&endlocal&goto :EOF                              set work=%file:,= %                              if "%work%" EQU "%file%" @echo DriveIcon DriveLetter DriveIconPathIndex DriveLabel - icon index missing.&endlocal&goto :EOF                              for /f "Tokens=1" %%a in ('@echo %work%') do (                               set file=%%a                              )                              if not exist %file% @echo DriveIcon DriveLetter DriveIconPath DriveLabel - %file% NOT found.&endlocal&goto :EOF                              if not exist %drv%:\ goto noar                              set work=%icon%                              set work=%icon:"=%                              @echo \[autorun\]>%drv%:\autorun.inf                              @echo ICON=%work%>>%drv%:\autorun.inf                              attrib -a +R +S +H %drv%:\autorun.inf                              :noar                              set lbl=%3                              set key1=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\%drv%\DefaultIcon                              set key2=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\%drv%\DefaultLabel                              @echo.                              @echo REG ADD %key1% /Ve /T REG_SZ /F /D %icon%                              REG ADD %key1% /Ve /T REG_SZ /F /D %icon%                              @echo REG ADD %key2% /Ve /T REG_SZ /F /D %lbl%                              REG ADD %key2% /Ve /T REG_SZ /F /D %lbl%                              endlocal
