Asus A716 report incorrect SD card Serial Number

[jo...@sky-power.com.hk]

I have been running this program in my ASUS A716 PPC for checking the
serial number of the SD card. It is interesting that HP/DELL/ACER with
PPC2003 report both Manufacturer ID and Serial ID in hexidecimal
format, while Asus A716 report only the Serial ID (Manafacturer ID
reported as not available), and the Serial ID is in decimal format.

What's more strange is that the serial ID reported is not correct.

Any body has any idea? (attached with my testing program)

Best regards,

IOCTL_DISK_GET_STORAGEID is implemented by the OEM, so perhaps ASUS is
simply not returning the correct information.
