Read SD Card CID (serial number)

I just moved blogs, so here's an overview of the SD card CID stuff. I've had some success reading the CID from an SD Card:

Where:

1) The OS is XP or Vista 2) The device is not attached via any USB gizmo. It works only in a card reader attached directly to the PCI bus. (Can scsi pass through get around this? It's not an ATA or SCSI command...) 3) Admin privileges...

What not to do:

1) IOCTL_DISK_GET_STORAGEID 2) GetFileInformationByHandle

As both these return a number assigned when the volume is created. It will change next time the drive is formatted. What I did:

Use IOCTL_SFFDISK_DEVICE_COMMAND to send command 10 (see the SD spec).

I don't think it works.

The Future?
