What is the maximum drive size supported by FAT32?

• A. 1 terabyte
• B. 2 terabytes
• C. 3 terabytes
• D. 4 terabytes

Answer: (B)

FAT32’s drive size limit comes from how it allocates space using clusters and how many clusters it can address. It uses 28-bit cluster addressing, so there’s a fixed ceiling on the number of clusters. With the common 512-byte sectors, that translates to a maximum FAT32 volume size of about 2 terabytes. In practical terms, Windows tools also cap FAT32 formatting at 2 TB. So the largest drive size FAT32 effectively supports is 2 terabytes. The smaller option is below the limit, while the larger ones exceed FAT32’s standard maximum.
