All storage product will display a lower than stated memory capacity when they are viewed on a computer. The reason for this discrepancy is the way in which manufacturers calculate a megabyte of memory.
32GB = 32,000,000,000 Bytes
1024Byte = 1K
32,000,000,000/1024 = 31,250,000 KB
1024KB= 1MB
31,250,000/1024 =30,517.57 MB
1024MB= 1GB
30,517.57 /1024 =29.8 GB
Therefore, the capacity of USB flash drive x 0.93 =Windows shown capacity.
