Hi.
I need to detect whether media in floppy or MO disk is write-protected or not.
I've tried to determine it by opening device "\\.\A:" with GENERIC_WRITE access permission, but it succeeds even if the media is write protected.
Any ideas ?
Thank you in advance.

I suppose you could try creating a file in it and see if it works:

HANDLE hTempFile;

GetTempFileName("A:\\", // dir. for temp. files
  "NEW",                // temp. filename prefix
  0,                    // create unique name
  szTempName);          // buffer for name

hTempFile = CreateFile((LPTSTR) szTempName,  // filename
  GENERIC_READ | GENERIC_WRITE, // open for read-write
  0,                            // do not share
  NULL,                         // no security
  CREATE_ALWAYS,                // overwrite existing file
  FILE_ATTRIBUTE_NORMAL,        // normal file
  NULL);                        // no attr. template

if (hTempFile == INVALID_HANDLE_VALUE) {
  printf("Read-only");
}

Hi.
I suppose this will work fine for floppy, but this might be wrong on MO disk, that is NTFS formatted and can have protected folders and so on.
