Why SD Card Shows Wrong Storage Capacity?

An SD card might show incorrect storage capacity due to following reasons:

1. You got an expansion card

Expansion card refers to the memory card that shows larger capacity than it should have had using illegal software. For example, the SD card only has 1GB storage capacity, but some manufacturers make it show as an 8GB SD card. Although it shows 8GB storage capacity, it can only be used to store 1GB data. When you store more than 1GB data to the card, the data might become corrupted or lost. Therefore, you should buy copyrighted SD card or other types of memory card. Never buy some fake SD card that is much cheaper than it should be.

2. SD card is infected with virus

Virus can spread and hide in your SD card, which may occupy storage capacity on your card. When an SD card is attacked by virus, it may show wrong capacity.
