My PC doesn't recognize the SD card

My PC doesn't recognize the SD card (the partition is shown, although). I tried it with Windows 10 and Linux. No luck. I used a tool called Diskgenius in Windows and I got this message:

Read Sector Error! Disk: RD2:MassStorageDevice(7GB) From Sector: 0. 2 Sector(s) Total. (Err:0)
Read Sector Error! Disk: RD2:MassStorageDevice(7GB) From Sector: 0. 2 Sector(s) Total. (Err:0)

I'm only wanna add more games and update the firmware.

Thanks.

Does the partition have a drive letter mapped to it?
Sometimes the firmwares for these devices don't. Meaning although Windows will know the partition is there, it won't know where the "front door" is, or so to speak.
