To begin you must understand a couple basics, I’ll make this easy. I’ll try my best. A GB is 1000 MB. But a computer is binary. Each bit can only be on or off. So 2 bits can make 2^2 different numbers =4. And likewise 3bits make 2^3 numbers = 8. Following this pattern you will see you cannot actually make 1000 (MB); 2,4,8,16,32,64,128,256,512,1024. And in the first we discussed that a GB is 1000 MB. So a GB or 1 billion bits / 1024 thousand bits. (A thousand, thousand is a million). The best you can (format) this 30 GB drive to is 2.92. The storage is really there, just the way it is formatted tells a different tale.
