#CHANGE CID SD CARD WINDOWS SERIAL NUMBER#
They came out reversed, and the endianness of the serial number and manufacturer date were unhelpful. It works on my laptop's reader, but not on a fan controller/card reading gadget plugged in to my desktop as its card reader is attached via a USB header on the mobo. If USB is involved in the chain, then the DeviceIOControl messages go to the USB host controller, and it doesn't understand them. The other biggy is that it only works when the SD Card is plugged into a reader that is attached directly to the pci bus. When I tried it on Vista 32 I got invalid handle errors. Weirdly it only works when compiled for the x86 platform (the build target in visual studio). My program (VB.Net) currently works only on Vista 64. I decided to try and get this CID number out, and I've managed to, but there are provisos.

IOCTL_DISK_GET_STORAGEID is useless - it gets a serial that Windows invents when it formats a volume.) I don't know.(edit - NO it isn't the same. I was asked if the number that my earlier program grabbed was this number from the CID. There we have 128 bits used to identify the device. The CID is the bit we are interested in, the Card IDentification register: This describes various commands that can be sent. It's call the simplified version of the physical layer spec. I was asked again this week about this, and pointed in the direction of the concise SD specification (you can only see the big one if you pay $$$$, as it isn't an open standard). I didn't know if the number was really the hardware stamped serial or whether it was just something windows dreamt up (like the volume serial you get with dir c:\).

I quickly wrote some code that demonstrated sending the message.
#CHANGE CID SD CARD WINDOWS HOW TO#
I wasn't sure how to deal with all the possible errors during burning - there were so many! I eventually got a vb.net program that could burn MP3s to CD. I used it to find out things that IMAPI couldn't tell you - like the exact media in the drive, and whether the drive was ready. I'd learnt about DeviceIOControl, and how it can be used to send messages straight to a device. I was working at trying to make a CD Burner, using COM Interop to talk to IMAPI on XP (before IMAPI2). There weren't any useful examples that I could find. But anyway the thread went along the lines of:Ģ) Someone suggested: Well use DeviceIOControl to send IOCTL_DISK_GET_STORAGEID to the drive.Īt the time I'd just been playing with DeviceIOControl, and had spent ages working out how to use it from.

Distribute your program on an SD Card, have it check the serial, and have it fail if the number doesn't match a hard-coded version. People want to do this as the number is factory stamped and unchangeable, so it could be used to protect programs from being copied. I got an email about a post from ages ago on the msdn forums about reading the serial number from an SD Card. That would not be a problem always working on the same type of cards.(Quick link to an executable, this might read the serial number on Windows XP/Vista/32/64 when you are not using a USB card reader (so when you have the card in a slot on the side of a laptop it should work - though it depends on the driver!)). You also wrote that it’s not just sending CMD26 on SPI mode and it’s need to knock SD or MicroSD card into firmware mode, then once done, they do accept CMD26 and permanently accept new CID values. So please, explain exactly with what kind of cards you were able to do the job possibly specifying their manufacturer, brand, type CSD and original CID (in order to know their manufacturer date).

I’m pretty sure I’d be able to do the job but unluckily I can’t find the right SD/MMC. I don’t know what do you mean about the different ways for different controllers you wrote, but in my opinion I think with the right cards isn’t too hard to achieve the goal. You wrote that it is possible but very time consuming do the job since you will need to come up with different ways for different controllers and also creating something (Universal) that will work with every controller is almost impossible. Once you can reach the target with a certain type of cards produced by a specific manufacturer, then surely you can repeat the job on others cards which are the same as model, brand and manufacturer. So actually your answer has to be interpreted academically rather than like a possible solution to the problem, being in the facts that in real life the things are far from being as you have described them.Īnyway, you wrote that each controller needs different methods, I guess you mean working on different cards produced by different manufacturer’s brands.
