I was extracting one tar.xz file via my Raspberry SD card, so the process must be completed after a long time but when I wanted to unmount the SD card I get one error which one other program (the extractor program ) is working on your SD card, So I thought it must not be real,so I used the unmount forcibly or something like this ... in the LINUX GUI, but now when I inserted the SD card again into my Laptop ( LMDE Linux OS) I get this error for accessing to Some parts of My SD card:

Error mountinf /dev/mmcblkop2 at /media/so/rootfs:command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/mmcblk0p2" "/media/so/rootfs" exited with no-zero exit status 32: mount:mount /dev/mmcblk0p2 on /media/so/rootfs failed: file exist

Also, you can see below:

SD card situation

So what can I do to solve this problem and have access to my Sd card files again?

And when this situation happens again, for example, some programs were working on my SD card but I cannot find them via my Linux toolbar, what could I do to avoid this kind of error to be happening again?
