Question SD card not mounted on Ubuntu Lite 3.6 - card reader not faulty

Hey guys,

I'm obviously a noob on Ubuntu (Linux in general) as well as on the forum, but I'll try my best to explain.

I've used my SD card in an android phone for a while and all of a sudden stopped working.

The phone doesn't "see" it at all, neither does my Windows 10 pc, but my camera picks it up and wants to format it. Therefore I assume it would be a good idea to try my work pc which I installed Ubuntu Lite 3.6 a week or two ago.

I obviously want to save the data.

I've tried EaseUS on Windows 10 to detect and recover, didn't work.

I followed a previous (old'ish) thread on this Forum
( )
and followed the commands up to a point - I have almost no idea what I was doing, but got the below which didn't match up completely to what the guy said it should:

Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 618995711 618993664 295.2G 83 Linux
/dev/sda2 618997758 625141759 6144002 3G 5 Extended
/dev/sda5 618997760 625141759 6144000 3G 82 Linux swap / Solaris

Meaning that he mentioned it should say /dev/sdc1...blah blah and then I could manually mount it.. so, does the fact that these results above only display /dev/sda... mean that it's not the sdCard? I assume sdc means sd card, right?

I hope you would be able to assist. Please note that I would need to know the full command to type in as I am not that familiar with all the commands, I'm only starting today.

Thanks & have a great day!

I'm thinking now.. it's a micro SD with an adapter, could the 'a' mean adapter?

It's not good news - the computer isn't picking up your SD card.
Your SD card should be seen as a usb. So it would show up as sdc or sdf for example.

sda1 is the Ubuntu OS, sda2 is a rather small extended partition and sda5 is the swap partition for the Ubuntu OS.
If it saw your SD card then it wouldn't say 'sda'. sda is only for hard disks.

Never heard of an SD card failing.
You should backup files and phone numbers onto a usb.
But then again, that's a bit like an SD card.

Welcome to LinuxQuestions.

/dev/sd was originally identified as a SCSI disk drive but since libdata all drives have a device ID of /dev/sdx. Where x is a,b,c..aa..zz and so on.

Typically the boot drive is /dev/sda, the next one discovered is /dev/sdb and so on. The device of the SD card should be the next i.e /dev/sdb however you did not post what type of card read i.e. USB or built in. If builtin and never used before it could require a special drive.

Check the output of the dmesg command to see if the reader and SD card are being recognized. SD cards can fail.

Boot up, then plug in the card, & in a terminal type
dmesg | tail
to see if it is recognized & given a drive assignment, likely to be sdc, but not always.
(If you get a designation, try manually mounting it.)
