Can't mount SD card

[norm.h]

I have an SDHC SanDisk 16 GB card which will not mount in the laptop, but works OK in the camera, and I can transfer pictures to the laptop when connecting the camera via USB. The card is not locked.
I also have an SD Kingston 128 MB card which mounts OK in the laptop.
Gparted tells me that the 128 MB card is formatted to FAT 16, but I can't establish the formatting of the 16 GB card.
Any help, please.........

Linux Mint 18.2 Mate 64 bit and the camera is a Fujifilm Finepix SL.

Edited to add:
The card used to work OK, and I'm wondering if this is relevant. I'm not sure when things went wrong, but may have been coincident with an OS update.

Code: Select all

The SDHC format is also reverse compatible, meaning that devices that can read SDHC cards can also read SD cards, but devices that can only read SD formats cannot use cards that have the SDHC format.

Code: Select all

sudo mount -t vfat /dev/<device> <mountpath>

[norm.h]

Thank you, but I don't know what to put in to describe the <device> and <mountpath>

[austin.texas]

You can get that information with the command

Code: Select all

lsblk -f

[catweazel]

You need to identify the device. Use this:

Code: Select all

lsblk

Once you've correctly identified it, do this:

Code: Select all

udisksctl mount -b /dev/sdX1

Where sdX is the identified device and 1 is the partition number.

Thanks for the help.
I got it mounted -once, and saw all the pics, as expected.
I need to run gparted to check and change, if necessary, the format, but couldn't get gparted to start, so did a reboot.
Now I'm getting this

Code: Select all

normh@normh-nspire2 ~ $ lsblk

[austin.texas]

Use sudo

Code: Select all

sudo udisksctl mount -b /dev/mmcblk0p1

[norm.h]

I've got it mounted, [hurrah!] and gparted is telling me it's formatted to FAT32, which is what one would expect for this size card.
So why won't it mount in the normal manner, 'cos it used to?

[norm.h]

So, mounted with an icon on the desktop, clicking the icon I get this....[screenshot] telling me that the file is of an unknown type, but gparted says it's fat 32.
And yet earlier, [when it was just called "disk"] the contents were displayed.

Another thing I've noticed is that when mounting in the CLI it takes quite a few minutes to be recognised.

[austin.texas]

What is the current result of

Code: Select all

lsblk -f

Can you see the contents in your file manager?

[norm.h]

lsblk -f shows:

Code: Select all

normh@normh-nspire2 ~ $ lsblk -f

Let's try something other than udisksctl.
Do:

Code: Select all

sudo umount /dev/mmcblk0p1

Code: Select all

sudo mount /dev/mmcblk0p1

[norm.h]

Code: Select all

normh@normh-nspire2 ~ $ sudo umount /dev/mmcblk0p1
[sudo] password for normh: 
normh@normh-nspire2 ~ $ sudo mount /dev/mmcblk0p1
mount: can't find /dev/mmcblk0p1 in /etc/fstab

Just tried a little experiment............
Restarted and put in the fat 16 128MB card - mounted straight away.
Restarted and put in the fat 32 16GB card - wouldn't mount.

Lowest common denominator seems to be the file system...............

Time to call it quits for today - many thanks for your help, and I'll look in again tomorrow.

I have a similar problem. If I format an SD card using an old Windows vista laptop it formats fat32, i can put it into the Linuxmint desktop and it mounts. If I format it using Linuxmint, it won't mount?

I also have this type of situation occasionally .
I have a bunch of used HDDs which are very useful for various projects , but they usually need reformatting .
Much as I love Linux ( and I use Gparted regularly ) there are times when I have to go back to Partition Wizard in Windows to get the job done ,
and it irritates me greatly !

There must be something going on "under the hood " , but I can't work out what this basic difference is .

Any clues anybody ?

30 minutes ago, I tried formatting an Sd card in the Linux machine, I changed the label at the same time.
It said 'Done', so I removed it and inserted it again.
Nothing, didn't mount. It also completely shut down my card reader unit. No lights. Zero.
Fired up ye olde laptop, used that to format the card. The card still had the old label on it, Linux had done nothing with the card, not even changed the label.
After formatting on Windows, I rebooted the Linux machine, the card reader was reactivated.
Inserted the SD card and it mounted and worked normally.

This has only started following recent updates over the last few months, and I have no idea why?

[norm.h]

It's reassuring, in a way, that I'm not alone here.

When I mount the card using the "sudo udisksctl mount -b /dev/mmcblk0p1" command it mounts after about a minute, but gives an "unknown file type" error when trying to open it.

gParted takes another minute scanning before finding it, then the drop-down menu to "Format" only gives the option to "unmount" - the rest are greyed out.

Methinks this needs a far better brain than mine to resolve...............

You can't perform operations like giving it a new format while it is mounted - so unmount it. And don't forget to click the APPLY button on the toolbar in Gparted to complete the operations.

[norm.h]

Ah yes, silly me....
Anyway, formatted the card in the camera [which doesn't say what format] then tried to mount in laptop - no change.
Then re-formatted as fat 32 in the laptop, [after mounting with the previous command] but still no change.

Guess I'll have to rely on connecting the camera with USB.

So almost 2 years on, after several new kernels, an upgrade to 18.3, and prompted by a post on another site I had another try.
The 128 MB SD card mounted right away, but the SDHC 16GB card took about 30 seconds to mount.
Both cards have only 5 or 6 images on them.

I therefore don't really have a problem, but it seems that it's a question of time to read the larger card.
Could I be right or am I talking rubbish?
