Following are the most common reasons why your SD card is not up to full capacity.

Why is my SD Card not Showing Full Capacity?

“Why does my 128GB flash drive only showing 32GB?”

Usually, it happens because of three main reasons:

  • Virus infection
  • Cheap or faulty SD card
  • SD card is not compatible with the card reader

Typically, this error is prevalent in large capacity flash drives such as SDHC or SDXC cards where the capacity of SD cards can even reach over 250 GB. So, if the either card reader or the host device does not support such high capacities,  the host device will create a smaller partition.

Simply, if a camera or a phone might support a storage drive only up to 32 GB. If you insert such a high capacity SD card which is 128 GB on onto such a host device, by default, the host device (camera or Phone) will create a partition of 32 GB and the remaining space will be marked as unallocated.

Or a typical virus attack might alter the Master boot record of the flash drive (MBR is like an index of the storage drive where all the details of the drive are maintained) and result in memory card capacity reduced.
