How To Clone Sd Card Serial Number
Internal SD Card Information Information about an SD card is encoded in its internal card registries. 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.
To clone Micro SD card in Windows is not complex anymore. EaseUS Partition Master allows you to clone SD card to larger SD card within 3 steps and you don’t need need to spend time copying files one by one anymore.
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.

I'll be receiving a GPS programs and maps on an SD card soon and would like to clone the card for backup. The software is locked to the serial number of the SD card, so just backing up the data isn't enough.
How To Clone Sd Card Serial Number
I suspect it is impossible to clone the card completely, including serial number, but thought I'd ask if anyone has investigated this and found a solution. I believe one can change the Volume ID of hard drives and imagine something similar being possible for SD cards. Partition magic free. I appreciate that unscrupulous people might clone such cards and sell copies, and I certainly don't want to facilitate that behaviour through this thread. Free download hp laserjet p2055dn driver. Given that the program and data on the card in question cost me $183 CAD, I do feel rather vulnerable, even if I can backup the contents of the card excluding the serial number. I have had SD cards become totally unreadable and unformatable and would like to be prepared should it happen with this one. Only freeware, please. Thanks, Larry ┊ 19/6/2007, 16:17 น.
