Hi
i have done program that read and write from USB and SD card the all image
include the FAT and MBR,Now at the end i want to close the Disk for Write, to
move the disk to be WRITE PROTECTED.
I am working with vista SP1 and with visual studio and with MFC application.
After i write new image to the SD CARD, I would like to Enable Write protect
that the SD willn't be available for Writing/Copy files ?
i have tried to do that with IOCTL_DISK_SET_DRIVE_LAYOUT_EX and to change:
pBuf->PartitionEntry->RewritePartition = FALSE;
the code is working but i can still write to the SD Card.
first i would like to know if this is the correct way to do that ?
any other way to write protect the SD CARD?

I believe i have found the define i want to use inorder to write protect the
flash:

MEDIA_WRITE_PROTECTED

But i don't see any function of set i can use to set the Flash to be write
protected?
Any one knows function for setting the write protected ?
