How to mount a memory card without errors?

Question

linux

When trying to connect a Raspbian memory card from a Raspberry Pi to a Linux Mint PC, the following error pops up:

Failed to mount Volume 8.0 GB
Error mounting /dev/mmcblk0p2 at /media/nikita/23c4ddbc-85fa-4cea-b96b-edae0bb138c9: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid " "/dev/mmcblk0p2" "/media/nikita/23c4ddbc-85fa-4cea-b96b-edae0bb138c9"' exited with non-zero exit status 32: mount: /dev/mmcblk0p2 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.

In this case, the boot partition is mounted normally, but there is no size with data. How to mount the second partition?

Answer 1

Does this card mount on a raspberry?
See what fdisk says:
and try to mount this partition without options:
where /dev/mmcblk0p2 is what fdisk actually says and /mnt is an existing empty directory

Answer 2

Line
indicates that the media is in read-only mode, which can be caused by two reasons:

1. A write prohibit switch is installed on the card body
   
2. The card is broken and the file system is damaged, and the card itself is write-locked due to damage
   . In any case,
   indicates that the file system has significant damage, or it is not ext4.
