Unencrypted, FAT sdcard doesn't properly mount via GUI

REPRODUCIBILITY (% or how often): 100%
BUILD ID = OS VERSION (Settings > About product): 4.4.0.58
HARDWARE (XA2, X10, X10 II, …): X10 II
UI LANGUAGE: en
REGRESSION: (compared to previous public release: Yes, No, ?): Yes

DESCRIPTION:

Mounting of sdcard with FAT filesystem via SETTINGS->System->Storage is not possible. It reads “Unsupported memory card” and attempt to mount ends up with pop up “The file system is incopatible. Formatting is needed”.
Sdcard is already formatted and used to work. The scard is not visible in UI i.e file browsers but is already mounted and visible via command line in /run/media.

PRECONDITIONS:

FAT formatted sdcard, (encrypted ext4 sdcard is mounted properly)

STEPS TO REPRODUCE:

  1. Have already working phone with 4.3.0.15 and sdcard with FAT filesystem
  2. Update to 4.4.0.58
  3. Reboot

Next reboot doesn’t change anything.

EXPECTED RESULT:

Sdcards properly handled .

ACTUAL RESULT:

as mentioned

Which version of File Browser are you using? If not done already, I recommend updating to version 2.5.1 from OpenRepos and check if it detects the SD card then.

Also, how can it be mounted if mounting fails? :thinking:

Yes in the latest 2.5.1 sdcard is visible but is not visible in any of the rest of file browsers.

For me it is mounted properly, content is visible by apps (eg, music). Only settings app does not show whole sd card just like in you case.
I have 2 partitions: one fat, second ext4. Both unencrypted.

I see; then it sounds more related to the system, not to File Browser.

O course . If it was a File Browser issue I would rise a bug report at File Browser at OpenRepos :).

Sure :slight_smile: I could have worded my reply better: it sounds like a system bug and I’m relieved File Browser isn’t affected and isn’t the culprit.

I couldn’t reproduce your bug. Can you explain with more details how you formatted your SD Card? Like which program did you use? On which system was your SD card formatted. What are the result of:

fdisk -l </dev/memoryCard>

I have no idea how formatted this SD card was. It has been working for years, already.

Disk /dev/mmcblk1: 3.7 GiB, 3980394496 bytes, 7774208 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device         Boot Start     End Sectors  Size Id Type
/dev/mmcblk1p1       8192 7774207 7766016  3.7G  b W95 FAT32

I could not reproduce either. Tried LBA and non LBA FAT, both were working.
Maybe your card went faulty. I had a certain amount of microSD who died from one day to the other.

I just tried with a died SD Card and unfortunately I don’t get the same message as @kan_ibal. It shows No memory card inserted.

@kan_ibal do you remember on which system you formatted your SD Card? On Android? Windows? Linux?
