Execute diskpart

[ChocJunkie]

Hi,

I'm trying to execute the 'diskpart' command during installation. I've tryed using ExecWait, nsExec::exec, ExecDos::exec and ExecCmd::exec but it seems I'm doing something wrong, because the command never succeeds.

code:
ExecWait '"diskpart" /s $\"C:\Documents and Settings\Administrator\Desktop\test.txt$\"'

${If} ${Errors}

  ...

${EndIf}

What am I doing wrong? >.<

Thanks.

CJ
