Mount sd-card
« on: 09 June 2011, 03:13:05 pm »

Hi,
i want to mount a sd-card.
`ls /dev/sd*` is "/dev/sda  /dev/sda1  /dev/sda2  /dev/sdb  /dev/sdc  /dev/sdc1". sda is the boot-sd card, sdc the esata device, so it seems to be the sdb. `fdisk /dev/sdb` = "Unable to open /dev/sdb" The SD-card is most certanly not broken; am i accessing the wrong blockdevice?

We don't know how static the device assignments are, but in this case it does seem that /dev/sdb is the SD card.

And fdisk /dev/sdb shouldn't give you the message that it does.

I would review the connections of the card/slot (did you ever open up the DP to mess with the micro-SD card?) As it happens, the board that handles the micro-SD card also handles the SD card, but at some level it must be possible for one to be working but not the other.

And possibly fdisk -l will tell you something.

English wikipedia says the same thing.

Well, I learnt something new today too. I don't believe I've ever seen an MMC card, but I see that my card reader has a slot marked "SD/MMC".
