SD card does not get mounted automatically

[wrongusername2]

I am using 16.04. Many times SD card does not automatically get mounted. In such cases I mount it manually, but OS won't let me delete the files. In that case only solution is rebooting machine. Please let me know if there is a better solution to come out of such stale situation? I have tried removing the SD card, that does not help.

sudo mount -rw /dev/mmcblk0p1 /media/afterwindows/junk1

Thanks

I think you can write and delete files via sudo (with root privileges). If you want your regular user ID to write and delete files, you can add some mount options. Maybe the following link can help,

Mount NTFS partition in a USB drive with custom permissions and owner

---

I guess that there is a Microsoft file system in the card, FAT32 or NTFS. Depending of your version of Ubuntu, you may need to install extra packages for exFAT.

If you have a linux file system (for example ext4), things are more flexible.

[wrongusername2]

Thanks for responding.

I am having slightly different issue in 18.04. Please follow these steps.

1) When I insert the MP3 recorder, partition gets mounted as read-only.

2) LSBLK shows the device & mount point

root@afterwindowsP50:/media/afterwindows# lsblk
    sdd      8:48   1   7.8G  0 disk 
    └─sdd1   8:49   1   7.8G  0 part /mnt/K-183

3) I unmount so I can remount with RW permission

 
            root@afterwindowsP50:/media/afterwindows# umount /mnt/K-183

4) Now LSBLK shows device but not mount point. That is expected.

root@afterwindowsP50:/media/afterwindows# lsblk    
sdd      8:48   1   7.8G  0 disk 
└─sdd1   8:49   1   7.8G  0 part

5) Now mount command fails saying device is missing.

root@afterwindowsP50:/media/afterwindows# mount -rw /sdd/sdd1 junk1
mount: /media/afterwindows/junk1: special device /sdd/sdd1 does not exist.

root@afterwindowsP50:/media/afterwindows# mount -rw /sdd/K-183 junk1
mount: /media/afterwindows/junk1: special device /sdd/K-183 does not exist.

This method of unmount & mount used to work in 16.04 but not in 18.04 anymore.

Please help me. I do not mind remounting just to delete a file but that is also not working any more. This method used to work on 16.04.

[sudodus]

You should specify the device, that is pointing to the partition, that you want to mount, /dev/...

This mount command line might work better, (assuming that junk1 is a directory made to be a mountpoint).

sudo mount -rw /dev/sdd1 /media/afterwindows/junk1

[wrongusername2]

Hi,

Thank you. Mount command worked, but filesystem still stays READONLY and does not let me delete the file

afterwindows@afterwindowsP50:/media/afterwindows$ sudo mount -rw /dev/sdc1 junk1

When I try to delete the file, I get following error.

REC087.WAV: Error removing file /media/afterwindows/junk1/RECORD/REC087.WAV: Read-only file system

MP3 player has two partitions (K1 & K1-183). By default K1 gets mounted under /media but K1-183 gets mounted under /mnt. Second difference is K1-183 stays read only where K1 is RW.


Here is the outputs of lsblk, blkid, lshw. May be this will help diagnose this issue.

I ran Fsck and that did not fix the problem'

sudo fsck -r /dev/sdc1

fsck from util-linux 2.31.1
fsck.fat 4.1 (2017-01-24)
0x41: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
1) Remove dirty bit
2) No action

I think I probably just use WIN10 for deleting files. This issue is taking way too much of time.


Thanks

[sudodus]

Please run the following command lines and post the results, when you have mounted the SD card with the recommended command (that I thought would mount it read-write),

sudo lsblk -f
sudo lsblk -m
sudo parted -ls
df -h
cat /etc/mtab

[wrongusername2]

Thanks for the response. i will post the results tomorrow. I also read that kernal marks the filesystem as RD-only if it encounters any error during mounting time. They suggested to run fsck.

Hi,


Sorry i was late getting the response. Here is the outputs. K-183 is the problem VOLUME. Here is lay out of MP3 player

Things look OK, as far as I can understand.

cat /etc/mtab

tells us

/dev/sdc1 /mnt/K-183 vfat rw,nosuid,nodev,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0

Both of these (/dev/sdc1 and /dev/sdd1) are mounted with read and write permissions 'rw', so at least with sudo you should be able to write.

If it is still not working, there is some other problem than mounting, either that the device is failing (for example a gridlocked memory card) or that the electronic system in the mp3 player is not allowing writing or not managing to make it work. Sometimes a peripheral device (in this case the mp3 player) is not working correctly with the computer hardware or software.
