batch file - How to pass to, and read from, diskpart.exe?

Question

How can I pass parameter from my batch script to diskpart.exe?

Batch file:

DISKPART /s diskpart.txt F

This is giving me an error:

Diskpart unable to process parameter

diskpart.txt:

SELECT DISK 3
ATTRIBUTES DISK CLEAR READONLY
ONLINE DISK
SELECT DISK 3
CLEAN
CREATE PARTITION PRIMARY
ASSIGN LETTER %1
EXIT

Also, how to read it from diskpart.exe?

As questions on SO deal with only a single specific issue, I'll attempt to offer a solution for the first question only, which is directly related to your code.

Here's my suggested replacement for what you're using:

@CALL :SUB F
@EXIT /B
:SUB
@(  ECHO SELECT DISK 3
    ECHO ATTRIBUTES DISK CLEAR READONLY
    ECHO ONLINE DISK
    ECHO SELECT DISK 3
    ECHO CLEAN
    ECHO CREATE PARTITION PRIMARY
    ECHO ASSIGN LETTER %1
    EXIT) | %SYSTEMROOT%SYSTEM32DISKPART.EXE

Please note, that I am not recommending that anyone tests this code, as it will destroy data, on any online Disk 3 on their system.
