Sd Card Serial Number
I can't seem to find a way to find the serial number of my SD card. I've looked in /dev/disk/by-uuid, but the same uuid is used across multiple Pis that I have. I've also used the blkid command, but I can only seem to get the size of the SD card. Any help would be appreciated. Edit: I managed to figure out where the 'serial number', aka CID, is found. For anyone who's interested, it's located in /sys/block/mmcblk0/device/cid.
The CID contains info on when the card was manufactured, by whom and what its intended content is. For more information on the SD card standard I plan on using the CID to encrypt the files on the SD card so no one can take my card out and simply copy what's on it.
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/mmc. Mar 29, 2013 - Serial Number is required for product registration. The product code is located on the back or the side of the USB Flash Drive. The product code is located on the bottom side of the CompactFlash card. The product code is located on the back of the SD card.
I have loaded a region from my 'blue nav' mapping program onto an sd card for my magellan meridian gps. As part of the copy protection system magellan requires that you go thru a reauthorization process to copy this region onto a different card.
My original sd card has failed for some reason and i cannot get it to reformat. It fails about 10% of way thru format and i can't read it at all.
Micro Sd Card Serial Number
When i tried to install the region onto a new sd card the gps software informs me that the serial number of the card in the original install now does not matcg the new card and will not allow me to proceed if i can rename the serial number of the new card to the old number it will save me the hassles of going thru the normal long-winded reauthorization procedure. I also have a number of other regions on the original card (that i backed up onto my hdd) to copy back to the card in case i should have any problems. I really don't want to have to go thru uploading all these regions again as it is very time consuming if you have to upload to the gps receiver rather than the sd programer.
