What's the systematic way of accessing an SD card? I've installed one in my reader, but nothing seems to progress. The end of dmesg gives:

[ 6647.300380] mmcblk0: error -123 sending status command, aborting
[ 6647.300392] end_request: I/O error, dev mmcblk0, sector 2952

None of that tells me what the dev might be. lspci:

And sudo fdisk -l just shows the hard drive.

I'm running Ubuntu 14.04.3.

Your dmesg output is full of errors. That SD card seems like it's quite faulty. That's why it isn't being made accessible to you.

  • It's a while ago now, but I'm pretty sure that card didn't have any trouble in other readers. – Opux Mar 13 '18 at 13:40
