Transfer data from external hard drive to another drive using variable drive path

Hi All,

I need to retreive data from a hard drive from computers that failed. My plan is to plug the hard drive as a external drive and retrieve the data to another external or local disk C: . Is there a way I would like to have the batch file ask for the drive letter where the data is stored before running and backup to current drive?

Please advice.

Thanks,
Vicki

Try something like this; set Source and Target to the required paths. The script is currently in test mode and will only display the robocopy command it would normally run. Remove the uppercase ECHO in line 15 to run it for real.
@echo off
setlocal
:Loop
set Drive=
set /p Drive=Please enter the drive letter for the backup: 
if "%Drive%"=="" goto :eof
if not "%Drive:~-1%"==":" set Drive=%Drive%:
dir Drive >NUL 2>&1
if errorlevel 1 (
	echo Drive %Drive% not found.
	goto :Loop
)
set Source=C:\
set Target=%Drive%\
ECHO robocopy.exe %Source% %Target% /e /r:0 /w:0

Open in new window

In a BAT file you can just use the SET /P command to prompt for the drive letter and assign it to a variable.  Something like this:

@echo off
set Drive=
set /p "Drive=Please enter drive letter:"
if "%Drive%" NEQ "" (
  REM Place whatever copy commands you need here...
  xcopy "%Drive%:\*.*" Z:\
)

Open in new window

Correction, sorry; missed some percent signs in line 8:
@echo off
setlocal
:Loop
set Drive=
set /p Drive=Please enter the drive letter for the backup: 
if "%Drive%"=="" goto :eof
if not "%Drive:~-1%"==":" set Drive=%Drive%:
dir Drive >NUL 2>&1
if errorlevel 1 (
	echo Drive %Drive% not found.
	goto :Loop
)
set Source=C:\
set Target=%Drive%\
ECHO robocopy.exe %Source% %Target% /e /r:0 /w:0

Open in new window

You could always give a little bit of a helping hand to choosing the drive too with a command at the top of your script to show some info, .e.g

@echo off
WMIC logicaldisk get caption, volumename, description, size, freespace
Set Drive=
set /p Drive =  etc.

Or even:

@echo off
echo Set objShell = CreateObject^( "Shell.Application" ^) > "%temp%\getpath.vbs"
echo set objFolder = objShell.BrowseForFolder^( 0, "Select a drive", ^&H10^&, ""^)>> "%temp%\getpath.vbs"
echo wscript.echo objFolder.Self.Path >> "%temp%\getpath.vbs"

for /f "tokens=*" %%a in ('cscript //nologo "%temp%\getpath.vbs"') do set folder=%%a
echo Now do copy from %folder:~0,2%
pause

Hi oBdA,

I am getting drive letter not found.

Hi Bill,
I am able to continue with the method you have suggested however, I need to be able to enter the source drive and be able to backup to current drive which can be a external drive as well.

Is that a possibility?
 Something like
xcopy /q/y "%Drive%:\Test\Backup\*.*"  %Current_Drive%:\

For the current drive you can just not specify a drive, i.e. \path\file is for the current drive or you can get the current directory using %cd%.  From that %cd~0,2% should be the drive letter.

.
My solution certainly allowed that, just adjust the destination of whatever copy command you use to specify the destination relative to whatever will be the current directory.

Did you see my second comment? The first version was missing the percent sign around "Drive" in line 6.
If the script is stored on the external drive, you can just use %~dp0 to access the drive.
@echo off
setlocal
:Loop
set Drive=
set /p Drive=Please enter the drive letter to backup: 
if "%Drive%"=="" goto :eof
if not "%Drive:~-1%"==":" set Drive=%Drive%:
dir Drive >NUL 2>&1
if errorlevel 1 (
	echo Drive %Drive% not found.
	goto :Loop
)
set Source=%Drive%\
set Target=%~dp0\
ECHO robocopy.exe %Source% %Target% /e /r:0 /w:0

Hi oBdA,

When I run the batch file, I get a error when I enter the drive letter. Please try to run it yourself.



@echo off
setlocal
:Loop
set Drive=
set /p Drive=Please enter the drive letter to backup:
if "%Drive%"=="" goto :eof
if not "%Drive:~-1%"==":" set Drive=%Drive%:
dir Drive >NUL 2>&1
if errorlevel 1 (
      echo Drive %Drive% not found.
      goto :Loop
)
set Source=%Drive%\
set Target=%~dp0\
ECHO robocopy.exe %Source% %Target% /e /r:0 /w:0

Line 8 had % % missing too.  %Drive% instead of Drive
