Therefore we can fix the problem by adding unallocated space to existing partition. The result is that you can make use of allocated space only. We all know that unallocated disk space cannot be used if there is not partition created on it. Thus the capacity you can use is the first partition. If there are multiple partitions on a flash disk, you can only see the first volume in File Explorer. Unlike hard drives, USB flash drive or SD card usually have only one partition, because Windows cannot recognize and access data stored on the second or other partitions. The USB drive is divided into two or more partition.Some system changes the partition of removable disk when writing booting data.
For instance, you burn a portable operating system on your removable drive, and you may find that the disk loses capacity.

The flash drive used to have 16GB storages, but it is 2.19MB in Windows Explorer only after it is made as a bootable drive. The problem is that the USB's capacity shrank. I fixed the system problem successfully but a new problem arose in the flash drive. "Lately I made a bootable USB drive on a USB flash drive for crashed laptop. Let's take a close look at a real cause about this issue:
That does not necessarily mean you have to buy a new one, as the capacity can be restored in many cases. It's possible that a 64GB flash drive shows as 54MB only. We can store large amount of data on SD card or flash drive so that we can take them to anywhere without difficulty. Likewise hard drive, USB disks come with different size, ranging 215 MB to 1TB. USB storage devices such as external HDD, USB flash drive, pen drive, memory card, etc, play important role in daily lives. Thus we should get a rough idea about this issue at least. It's really annoying to be unable to use all USB drive's storage, but this issue just happens due to various reasons.
