I have an application for my Hermes (Cingular 8525) that came on a 1-Gb micro-SD card. I have backed up the application in a RAR file and unRARed it to a larger (2-Gb) micro-SD card.
When I try to run it, I get a hardware ID error. It seems that there is a file that likely contains the CID identifier of the micro-SD card, which is unique to the card and is not affected by formatting. What I would like to know is if there is any application which will run on either my Hermes or my PC which will read out and display the CID identifier of an SD or micro-SD card.
Actually when I bought iGo, I asked for a 2Gb micro-Sd and they told me that they only supplied it on a 1Gb card. On top of that, they charged an extra amount because it was on a micro-SD card instead of a regular SD card. The price was really quite exorbitant - $300 including shipping just for the map of Israel. TomTom maps are $100 for all of North America (and only $50 if you do an annual upgrade).

However, for some insane reason, iGO is the only GPS map software for Israel - Garmin and TomTom don't have it. In looking over the supplied software from iGO, I noticed that there is one file called license.db which seems to contain the CID number of the card. I thought I would experiment with putting their app on a larger card and hacking that file to change the number to the CID of the larger card - except that I can't find any utility that will read out the CID. Hence my post. I can't experiment with this right now, but you might try popping the card into a USB reader attached to a laptop or PC. Then, on that machine, open a CMD (DOS) window, browse to the root of the card, and type DIR and press enter.
The resulting screen should show you a list of all the files in the root directory of the card. The second line in that list should tell you the 'Volume Serial Number'. Is THAT what you're looking for?

If so, you should also be able to edit it, using a program like WinHex. Simply make the large (2GB) card have the same VSN as the one the software was delivered on. Hope this helps, -pvs. Quote: Originally Posted by pvs I can't experiment with this right now, but you might try popping the card into a USB reader attached to a laptop or PC.

Hope this helps, -pvs. I've got the CID in C# in Windows XP/Vista. No luck with Windows Mobile 2003 SE (I haven't got anything newer to try it with). You send IOCTLSFFDISKDEVICECOMMAND with deviceIOControl. Works only with SD cards plugged into a reader attached directly to the pci bus, it doesn't work with usb readers, you need admin rights for the call, it needs to be compiled for x86 instead of AnyCPU, it's flaky. My pocket pc experiments have ended in misery.
I think the driver for the SD Bus Host must be programmed to deal with the calls or something. Rocket from the crypt live from camp x-ray rar. It's too low level for me, my understanding is minimal. Hi, im searching too for a way to copy igo license card i think this tool is probably the first step to success copy the file to your PPC insert the card you want to now the id and run (works only on PPC) The license.db works together with the card id i found a field by opening the license.db with normal hexeditor where the id is stored ( field called 'secid' ) but no way to change it because the file gets unreadable for igo we need a way to change the id in the license.db sorry for my bad english.
Internal SD Card Information Information about an SD card is encoded in its internal card registries. Intel chipset drivers download. One of these is the Card Identification (CID) Register, a 16 byte code that contains information that uniquely identifies the SD card, including the card serial number (PSN), manufacturer ID number (MID) and manufacture date (MDT). The CID register is set when the card is manufactured and cannot be changed after it is set. (According to SD card specification the information is only to be written once, however if a card does not conform to the specification this information could be changed!) How to read the CID from an SD card One way to read the CID is to use a laptop with an SD card slot.
Card readers in laptops are usually connected directly through the PCI bus (or IDE bus). This will not work through a USB card reader because the command to retrieve the card information is intercepted and not understood by card readers. Not all computers with built-in card slots will work, some internal card readers are connected through a USB bus. Assuming you have the proper hardware, there are several methods you can use to get the card information. With Linux, reading the internal SD card information is simple. Insert the card and look under /sys/block/mmcblk0/device/ (this location may change depending on your platform, it may be mmcblk1 or in a different location). Under this location you will see several available that include the CID and CSD registers and the information inside it.
To view the CID, the command is cat /sys/block/mmcblk0/device/cid (the exact location may be different) What information is in the CID? The following information is stored in the CID: Name Field Linux attribute. Description Manufacturer ID MID manfid Assigned by SD-3C, LLC. OEM/Application ID OID oemid Identifies the card OEM and/or the card contents. Assigned by SD-3C, LLC. Product Name PNM name 5 characters long (ASCII) Product Revision PRV hwrev, fwrev Two binary coded decimal (BCD) digits. Each is four bits.
The PRV is in the form x.y. The PRV can also be found by using the hwrev and fwrev, where x=hwrev and y=fwrev Serial Number PSN serial This 32 bit field is intended to be read as an unsigned integer Manufacture Date Code MDT date Manufacture date is stored in the form yym (offset from 2000) CRC7 checksum CRC 7 bit code used for checking errors in the card register. these are the attribute titles used for the card in Linux For more information, refer to the. How can I use the information from the CID?
The CID information can be helpful in identifying counterfeit memory cards. We include the CID data in our so you may compare it with your cards.
In some versions of Android, and other variants of Linux, it's possible to get the serial number of a mounted SD card, e.g. By reading the contents of /sys/class/mmchost/mmc0/mmc0:0001/serial or /sys/block/mmcblk0/device/serial (specific numbers may vary). In my testing this has worked pretty reliably, as long as the SD card is inserted in a built-in SD card slot (not mounted via USB adapter). But as of Android 7.0 Nougat, the to this information, at least on some devices.
I tested this by running a test app on a new Alcatel A30 GSM (Android 7.0), and in fact the above approach fails with a permission error: java.io.FileNotFoundException: /sys/block/mmcblk0/device/serial (Permission denied) at java.io.FileInputStream.open(Native Method) For future reference, we (testing from an adb shell) have permissions to ls -ld the following:. /sys/class/mmchost but not /sys/class/mmchost/mmc0. /sys/block but not /sys/block/mmcblk0 Since the above approach no longer works,. Is there another way to obtain the serial number of a mounted SD card in Android 7.0 or later?. Failing that, is there any documentation or other statement from Google on plans for providing or not providing this function? I haven't found anything in the Android, but maybe I'm not searching right. To make sure the question is clear, I'm talking about what an ordinary (non-system) app running on a non-rooted device can do, with any permissions that an app can normally request and receive.
FYI, the /sbin directory doesn't seem to be readable, so commands like /sbin/udevadm aren't an option. In Android N access to /sys nad /proc was significantly restricted, this was done to provide stricter sandboxes where applications run. This is explained in as intentional. Actually its not said that all the data in /sys is not accessible, and Google is open to allow access to other files from this location: If there are specific files in /sys you believe should be available to applications, but are not, please file a new bug where the request can be evaluated. For instance, /sys/devices/system/cpu is available to all processes, so it's inaccurate to say all of /sys is restricted. I have a bad feeling that google is making changes similar to Apple where it is not allowed to gain hardware id-s.
If that is not resolved then the solution is to use google account IDs instead. But I am aware it is not always possible, and will require major changes in business logic (licensing etc.).
Change Sd Card Serial Number Windows
Hopefully your will be considered positively. Another related SO I found.
I have dozens of SD cards that I need to keep track of for a project. Right now, they each have a number physically written with permanent marker on the outside. This is OK, but I want to see if there is something unique that's built into each SD card that I can record. So far I am aware of:. The SD card's CID, which usually (not always???) includes an unique serial number. I can't find a straightforward way to read this off an SD card in Fedora 21. Some pages say that unless you have a card reader directly connected to the PCI bus (and not via USB), you can't see the CID.
Volume/partition serial number. This might work but I understand that this changes every time the card is reformatted, which is something we do from time to time. So not a good option. Just labelling the SD card volume with my own unique naming system. This is too easy to change, and I might as well just stick with writing the numbers on the outside. So, I guess my questions are:. Is there a way to reliable read the CID off my SD cards to get serial numbers via a USB card reader in Fedora 21 or other GNU/Linux distributions?.
If not, are there other ways of using existing unique identifiers in an SD card or another system for uniquely identifying SD cards? Whatever blkid returns will change whenever the data stored on the SD-card changes. This is much different to the CID or serial number. If you made a dd if=/dev/sdcard1 of=/dev/sdcard2 count=2, changes are very hight that blkid /dev/sdcard1 will be identical to blkid /dev/sdcard2. Also the final remark of the answer is misleading: the UUID is derived from the data stored on the SD card, and not the card, clearly most every USB reader will let you read the content of th SD-card.
What is still not possible is to access the CID. – Mar 8 '17 at 14:00.
I just got a new clio with the tomtom carminat built-in sat nav and thought I would take a copy of teh SD card to be safe. I followed tomtom home instructions for backup and then did a recovery to a new sd card - which all worked fine. But when I tried to use the copied card the tomtom said something like 'you are not allowed to use this map'. I'm not sure if this is supposed to work or if there is some kind of link between the original sd card serial number and the tomtom unit? If the backup/restore process only works withe th original card then not sure what the point is as most likely its lost/damaged cards that are the main problem.
You CAN make a copy of your SD card onto a bigger card - I'm using a 4GB card in mine and the original TT SD card is in my desk drawer right now. The map is not solely tied to the original SD card. The procedure is a complete pain and I can't remember it properly, so try first of all simply copying the card using Windows Explorer and see if it works. I don't think it does. So try starting Carminat without a card (remember first to choose to Remove card and wait for it to say you can now remove it).
When it objects to no card, stick a blank card in and see how it reacts - it'll probably still object but at some stage it should say the card has been initialised or prepared. Then take the card out and try it in Home on your computer. The real pain in all this is that you can't use 'Operate my Carminat' on the computer, so to see what works and when, is a case of going out to your car each time. I'm sorry, but for some reason I haven't got a spare SD card at the moment, otherwise I'd do the experiments and tell you what succeeds. I've just found the following, which sounds right. Start the car and switch on your Carminat TomTom.
Wait for the navigation screen to appear. Insert the new memory card into your Carminat TomTom. Wait for a few seconds so that the card can be initialised by your Carminat TomTom. Remove the card from your Carminat TomTom and insert it into the card reader connected to your computer.That would have the new SD card initialised. The next step could be to copy (using Windows Explorer) the contents of your original card to the new card - it is probably best to do this by copying the original to a folder on your PC, then copying from that folder to the new card.
