To save the current path as a variable (much easier: %__CD__:~,1%):

FOR %%A in ("%__CD__%") do set "disk=%%~dA"
set "disk=%disk:~0,1%"

Edit: Alternatively,

FOR /F %%D in ('"prompt $N&cmd/k<nul"') do set "disk=%%D"

You may not need an additional for loop to define the driver, because you have a system variable %cd% or %__CD__% for this task, use it through the substring variable 

%CD:~0,1%

rem :: or...
%__CD__:~0,1%

@echo/%CD:~0,1%

rem :: or...
@echo/%__CD__:~0,1%

@set "drive=%CD:~0,1%"

rem :: or...
@set "drive=%CD:~0,1%

@set "drive=%__CD__:~0,1%"

Obs.: Also works %CD:~,1%, %__CD__:~,1%
