Reading physical drive

[simplix]

Good day!

I'm trying to read a physical drive, but I get an error. Please tell me how to do it?

code:
;File Access Modes

!define GENERIC_READ         0x80000000

!define GENERIC_WRITE        0x40000000

;File Sharing Modes

!define FILE_SHARE_READ      0x00000001

!define FILE_SHARE_WRITE     0x00000002

;File Creation Flags

!define OPEN_EXISTING        3

!define INVALID_HANDLE_VALUE -1



Section Main



  StrCpy $3 "\\?\PhysicalDrive0"

  System::Call "kernel32::CreateFile(t r3, i ${GENERIC_READ}|${GENERIC_WRITE}, \

    i ${FILE_SHARE_READ}|${FILE_SHARE_WRITE}, i 0, i ${OPEN_EXISTING}, i 0, i 0) i .r2"

  ${If} $2 != ${INVALID_HANDLE_VALUE}

     System::Alloc 1

     Pop $0



     System::Call "kernel32::ReadFile (i r2, i r0, i 1, *i .r4, i 0) ?e"

     Pop $5



     System::Call "kernel32::GetLastError() i() .r1"     

     MessageBox MB_ICONINFORMATION|MB_OK "Return code: $5, Error code: $1"



     System::Free $0

     System::Call "kernel32::CloseHandle(i r2) i.r3"

  ${Else}

     StrCpy $5 "Error: CreateFile failed for \\?\PhysicalDrive0"

  ${EndIf}



SectionEnd

ReadFile must return non-zero, but it returns 0 and GetLastError returns 80.

Thanks for your help!
