• RMPartUSB FAQs

Q1. How can I use RMPartUSB in my Windows script files (e.g. .cmd or .bat files)?

A1. Most functions of RMPrepUSB are available in RMPartUSB and so can be scripted - except you will need to use XCOPY to copy files to the USB drive once it has been formatted.

Some special commands and code examples are shown below (code in bold, keywords in red bold):

RMPARTUSB LIST

====================================================

*DRIVE 1 - 7.5GiB TakeMS MEM-Drive Smart USB Devi Fw=0.00 H:

DRIVE 2 - 7.5GiB Verbatim STORE N GO USB Device Fw=5.00 J:

RMPARTUSB LIST ALLDRIVES

====================================================

*DRIVE 0 - 232.8GiB ST3250820AS ATA Device Fw=3.ADG Sno=202020202020202 C:

DRIVE 1 - 7.5GiB TakeMS MEM-Drive Smart USB Devi Fw=0.00 H:

DRIVE 2 - 7.5GiB Verbatim STORE N GO USB Device Fw=5.00 J:

RMPARTUSB FIND > drv.cmd

example drv.cmd file produced is:

SET DRIVE=1

SET DRIVEDESC=TakeMS MEM-Drive Smart USB Device

SET DRIVESIZE=8086618112

SET DRIVELETTER=H:

SET DRIVE1DESC=TakeMS MEM-Drive Smart USB Device

SET DRIVE1SIZE=8086618112

SET DRIVE1LETTER=H:

SET DRIVE2DESC=Verbatim STORE N GO USB Device

SET DRIVE2SIZE=8011120640

SET DRIVE2LETTER=J:

(Note: DRIVE, DRIVEDESC and DRIVELETTER are used for the FIRST USB DRIVE to be found, if more than one USB drive is expected to be in the system then use the DRIVEn variables).

Example of how to use in a batch file:

RMPartUSB FIND > drv.cmd

call drv.cmd

del drv.cmd

echo Drive 1 is a %DRIVE1DESC% with a size of %DRIVE1SIZE% and a volume letter of %DRIVE1LETTER%

Or an alternative that does the same thing without needing a temporary file:

FOR /F "tokens=*" %%A IN ('RMPartUSB FIND') DO %%A

echo Drive 1 is a %DRIVE1DESC% with a size of %DRIVE1SIZE% and a volume letter of %DRIVE1LETTER%

Another example - ask user to select a USB drive and copy files to it:

RMPARTUSB LIST

set /P DD=Please enter the USB Flash drive number you want to use:

rmpartusb DRIVE=%dd% WINPE FAT32 2PTN VOLUME=WINPE

if errorlevel 1 echo COMMAND FAILED!

if errorlevel 1 goto :EOF

rmpartusb DRIVE=%dd% GETDRV > drv1.cmd

set USBDRIVELETTER=

call drv1.cmd

del drv1.cmd

If "%USBDRIVELETTER%"="" goto :EOF

xcopy /herky C:\mysourcefiles\*.* %USBDRIVELETTER%\*.*

echo all files copied!

example drv1.cmd file produced is:

SET USBDRIVE=1

SET USBDRIVEDESC=TakeMS MEM-Drive Smart USB Device

SET USBDRIVESIZE=8086618112

SET USBDRIVELETTER=H:

Another example - ask user to select the USB drive, partition and format the drive, add grub4dos and copy files to it:

@echo off

REM change to our working folder

pushd "C:\Program Files (x86)\RMPrepUSB"

REM list all USB drives so user can see them and their drive number

RMPARTUSB LIST

REM Ask user for a drive number

set /P DD=Please enter the USB Flash drive number you want to use:

REM execute RMPARTUSB (insert SURE if you don't want the user prompt)

RMPARTUSB DRIVE=%dd% MSDOS FAT32 2PTN FORCELBA VOLUME=WINPE

if errorlevel 1 echo RMPARTUSB COMMAND FAILED!

if errorlevel 1 goto :EOF

set USBDRIVELETTER=

REM get the drive letter of the newly formatted drive

FOR /F "tokens=*" %%A IN ('RMPARTUSB DRIVE^=%dd% GETDRV') DO %%A

If "%USBDRIVELETTER%"=="" goto :EOF

REM install grub4dos

grubinst -v --skip-mbr-test (hd%dd%)

If errorlevel 1 goto :EOF

REM use touchdrv to ensure MBR changes are not removed by Windows!

touchdrv %USBDRIVELETTER%

REM copy grldr file over which is needed by grub4dos

copy grldr %USBDRIVELETTER%

If errorlevel 1 goto :EOF

REM copy over boot files (assumes a menu.lst file has been added for use by grub4dos)

xcopy /herky .\mybootfiles\*.* %USBDRIVELETTER%\*.*

If errorlevel 1 goto :EOF

echo Finished - All files copied!

Q2 How can I determine the correct command for RMPartUSB?

Use RMPrepUSB, set your options and click the Prepare Drive button and note down the command line that it uses to call RMPartUSB (uncheck 'No user prompts' checkbox). Otherwise typing RMPARTUSB on the command line should give some help.
