Bug Description

When I insert an Ext4 formatted SD-card (64Gb), I get an error notification stating 'Failed to add storage device'. From the terminal I can mount it as expected (sudo mount /dev/mmcblk0p1 somewhere).

I tried the card with its original file system as well (exfat), but that causes the same problem.

Device: Meizu Pro 5 Ubuntu (OTA-10.2, OTA-11)

If formatted from the External Drives app, eventually the SD can no longer be read. `sudo fdisk -l /dev/mmcblk1` has the following output:
fdisk: cannot open /dev/mmcblk1: Input/output error

Tested with Aquaris M10

Jonathan:

Your issue seems different from the one reported by me (I have no problem reading the SD-card with fdisk -l, it just doesn't get mounted).

You may want to open a new bug instead.

Yes it was different. My issue was that I was using SDXC, while SDHC cards have no issue. However I did try and ext4 formatted SDHC card and I got the message "Unable to mount SD card. Check to see if it was formatted correctly." I was also able to mount from the command line, but I did not like the behavior. Instead I decided to reformat the card as fat32 and I had no issues.

Hi all,

The issue is reproducible using SDXC sd card, SanDisk Ultra 200 GB. Could you test it again?,

Thank you.

Regards.

After continued testing I found any class 10 SD card had problems on Aquaris M10, even 16GB and 32GB SDHC cards. I am currently using a class 4, 32GB, SDHC, and the device does not have any more problems.
