Micro sd card reading problems

Linux Support
1

Hello.

I have just purchased a 64gb micro Sandisk sdxc uhs-1 card. I cant get Peppermint 5 or Mint16 to recognise it properly. My Android phone won’t recognise it either.

Any suggestions.

Screen shot attached.

2 
sudo apt-get install exfat-fuse exfat-utils

Now try inserting the card again

Thanks Mark.
It’s now showing it as a 29gb volume but then it says it has 63.8 gb space.
Do I have to partition it to two 32 gb volumes?

Dunno, does GParted ot “Disks” show any unpartitioned space ?

and what’s the output from:

sudo fdisk -l

Hi Mark.

First the out put;

Here is a screen shot of Gparted

I think it is more than likely that your devices cannot read the SDXC cards so they default to SDHC (4GB to 32GB). See here
Try a different card reader capable of reading SDXC cards.

I agree with SeZo … are you 100% sure your card reader is SDXC capable ?

Thought I do find it odd that fdisk sees

total 57626624 sectors

yet only uses

32768 → 124735487

Can you explain this statement:-

It's now showing it as a 29gb volume but then it says it has 63.8 gb space.

Where does it say that there’s 63.8GB of space ?

Yep SeZo is right. card reader problems.

Now shows the full 64gb.

Mark. With regard to the question of showing 63gb I was confusing it with another partition.

Thanks for the help Mark and SeZo. :slight_smile:
