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.
3. SD card is corrupted
If an SD card is damaged, it may also say wrong storage size. For example, if the file system of SD card is corrupted turning to RAW, you will find its capacity would show 0 byte.
If you bought an expansion card, you cannot fix the problem. If the SD card shows wrong capacity due to virus infection or file system corruption or other logical failures, you can restore full capacity of SD card by formatting it with following methods:
1. Format SD card back to original storage size in camera/phone/pc

Here is a related Case:
My 8GB SD card shows as two volumes in Windows 8. One volume shows 56MB capacity healthy, and the other one shows about 7GB as unallocated space. PC only allows me to format the partition that has 56MB capacity, but disables me to extend the partition by adding the 7GB unallocated space to it. I cannot format the unallocated volume, either. – A user from tomshardware.com
