I'm trying to mount a Micro SD card. I'm using Ubuntu 20.04.2. When I put a new micro SD card in, it automatically mounts and shows all files.

When I run: sudo mount /dev/mmcblk0p1 /media/micro && cd /media/micro, the commands work and shows the directory of the sd card.

When I put this card into my dash cam it, reformats it. I put the card in a windows machine it shows it as a FAT32 file system and shows all the video files. I can transfer to a thumb drive and it read all files fine on my Linux machine.

However When I put the SD card in my Linux laptop nothing. The command sudo mount /dev/mmcblk0p1 /media/micro I get:

aaron@aaron-K46CA:/media/micro$ sudo mount /dev/mmcblk0p1 /media/micro 
mount: /media/micro: more filesystems detected on /dev/mmcblk0p1; use -t <type> or wipefs(8).

Running: aaron@aaron-K46CA:~$ sudo mount /dev/mmcblk0 /media/micro
[sudo] password for aaron: 
mount: /media/micro: wrong fs type, bad option, bad superblock on /dev/mmcblk0, missing codepage or helper program, or other error.

If I run sudo fdisk -l, I get:

Disk /dev/mmcblk0: 29.74 GiB, 31914983424 bytes, 62333952 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

Thanks!

  • What do you get after you run sudo lsblk ? I suspect that you will get more than one disk partition showing up beneath mmcblk0 – mondotofu Mar 15 '21 at 01:28
  • You can got to the top left corner of your screen "Activities" and search for "Disks" aka "Gnome Disks" . It will tell you what sort of format it has detected for the partitions on your SD card, how large they are, etc. I hope this will give you the idea of how to mount the card and get what you need instead of having to run to a windows machine to transfer your dash cam videos. – mondotofu Mar 15 '21 at 01:31
  • Running sudo lsbik: mmcblk0 179:0 0 29.7G 1 disk └─mmcblk0p1 179:1 0 29.7G 1 part – Aaron Possien Mar 15 '21 at 02:39
  • When I look22.4G 0 dis at "Disks" I get: Two partitions of the 32gb sd card, sdb (4mbfree space) mmcblk0 and (partition 1, 32gb, unknown, and Read Only) mmcblk0p1 – Aaron Possien Mar 15 '21 at 02:40

Either

$ sudo mount -t vfat  /dev/mmcblk0p1 /media/micro   #fat32

OR

$ sudo mount -t ntfs-3g  /dev/mmcblk0p1 /media/micro    #ntfs

should work
