I still can't get my sd card to read. this is becoming worthless.

[Teunis]

Oops, yes xfat needs to be installed separately...
And xfat is what you expect with cards over 32GB.

[vinnywright]

OK then ,,,,,I do not think exfat is the problem UNLESS the size of the file system has some extra affect on things ,,,(I do not think so)

hear is a test I did on this just now .......... I logged the progress of the experiment in a text file and am just going to copy it @hear and wrap it in CODE tags,,,,,,,,,,I have a hard time spelling and typing long responses

 
 first run ,,,,,card NOT mounted in 14.04 ----exfat-fuse and exfat-utils have been installed .

dolphin sees it and will mount it .............copying some files to it and booting back to 16.04 , that dose NOT have exfat-fuse and exfat-utils installed.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx


back in 16.04 , on plugging in the sd card formated exfat and containing some picks ,,,,,,
the device notifier dose pop up BUT can not mount it and it DOSE show in dolphin but again will not mount 

but dose show.

parted shows the same as in 14.04 ..................

SO unless (and again I do not think so) the size (mine is 1GB) of the file system matters the fact it may or may not have been exfat sould not keep the sd-card from at least showing up some where ,,,,,,,,,,,O and hear is the "lsblk"

I do think he was hit by the bug I linked to @hear https://www.kubuntuforums.net/showth...l=1#post385634

32GB is the maximum partition size for FAT32.

[vinnywright]

32GB is the maximum partition size for FAT32.

I still contend that if his card reader was working properly it would not matter what was on it , file system type , size , or lack their of ,,,,,,it still should have shown up in parted , lsblk , the device notifier , dolphin ,, somewhere .

I have an internal SD card reader on my Asus Laptop and I found that when I was given an SD card from a camera, I could not read it. I found that I needed to install exfat-utils to read the card.

I am not sure, but I may have had to install mtpfs and jmtpfs, but these may have been installed to access my Wife's Samsung Galaxy phone to transfer files.

Regarding blackmachismo having trouble with kmail, I must confess that I am a Thunderbird user and have not had any trouble with it.

[MoonRise]

Just to note, I had issues reading 64GB micro. The problem in Linux was I had to install xFAT and that solved all issues I had. So, those who mention that, you are probably correct here as I've never had any issues with Linux on any machine that had a build it card reader. the ones over 32GB was the only time and xFAT did fix that.

to "read" it yes ,,,,,,,, but the system should still have showen it ,,,,,,,,the OP could not even see it in parted different problem altogether look at his dmesg output @hear https://www.kubuntuforums.net/showth...l=1#post385622

Those messages go to kernel issues and I believe I read in this chain or the other one where someone, maybe you Vinny, to try older versions.

right ,,,,the "sdhci debug_quirks=0x40"

is what I wanted him to try ,,,,but as a kernel boot line option in grub as a test .

Yes, definitely, jmtpfs talks MTP over a cable.
