trader18,
Bit more information would be useful (like operating system, how you partitioned it, what filestore, machine spec/age). Eg, 2k & XP have maximum 32GB (very close to your 33GB) size for FAT32 partitions. Some motherboards/bioses have 32GB max disk size they can see (so if they can see larger disks, they appear as 32GB).
Have you checked (either with fdisk - win9x/ME or disk management - 2k/XP) there is unused space? If you want one large partition & mobo/bios supports it, you'll either need to start from scratch (backup, delete existing partition, create new one) or use something like partition magic to extend size of your existing partition.
