When an SD card is not showing full capacity, it is usually because of logical errors, compatibility issues or technical errors like bad sectors. Logical errors can be taken care of by doing some quick fixes. If you want to know why your SD card might be showing the wrong size on any other device other than computer, you might want to first check with the compatibility. For example, a few cameras only support 32 GB memory cards. Start with verifying the device.
If you have bought the SD card new and it does not have the same storage space as claimed, it might also be that the product is not genuine. Here are a few other important reasons why an SD card might not be showing full capacity.
Why is my SD Card not Showing Full Capacity?
“I have a 128GB SD card which is not showing full capacity in my Windows 10 computer, I am not able to format it to the correct size with Windows format tool. Why does my 128GB microSD card formatting to lower capacity and 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.
In such cases, your SD card or any kind of flash drive will reduce the storage space.
The other scenarios because of which memory card capacity is reduced might be Bad Sectors. Bad Sectors are damaged storage sectors that don’t respond to read or write commands. 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 being reduced.
