![]() ![]() ![]() Thank you for the response.I am able to get unique 'Volume Serial Numbers' from the SD card when using the dir command in MS-DOS, though this number changes every time the card is formatted:I:dirVolume in drive I is WIPEDVolume Serial Number is C688-0DDD. Fedora 9.īacktrack 4I had the same results with each combination of card reader/SD card. Adata Suber SD Duo 1.0 GBOperating systems. Would this be the case? And if so, is it possible to force the mmccore driver to pass through the USB card reader and be used directly with the SD card?Īre there any PCI MMC/SD card readers that would be able to have lower level access to the cards?Thank you in advance.Information:Card readers. I had read that the sgraw command allowes for sending arbitrary HEX formatted commands to a device, though none seemed to pass through the reader to the SD card itself (I tried the binary commands that where listed in the MMC spec and the SD spec).When looking at the linux drivers for MMCs and SD cards (sdmod, mmccore) it seems that if the mmccore driver were to be used to interface with the card, the serial number ( cid.serial in 'mmc.c' in mmccore) would be obtained during the card initialization period. I was running various commands on the device (/dev/sdc and /dev/sg3) trying to get any response from the SD card, but I was only getting responses from USB connected reader. Under Linux I have found the sg3-utils that send SCSI instructions to devices. ![]()
