Issue: SD Card Is Not Showing Full Capacity
"I bought a SanDisk micro SD card a year ago, and it's 8GB. This morning when I transferred some photos from the SD card to the other on my Windows 10 computer, to free up some space, later I check its property, it shows around ~500MB capacity. That's not true. What happened? It should be as the original 8GB I think."
As far as we concerned, the issue of SD card showing the wrong size mainly owes to three aspects.
- 1. Cheap and faulty SD card bought from dishonest vendors
- 2. Incompatible with card readers or host devices
- 3. Infected by computer viruses
