Why is the 250GB hard disk having less than 233 GB? This was a question that one of my friends asks me after buying a new 250GB Hard Disk. I really didn’t ask that question to myself. So, I couldn’t answer that instantly. After a few days of information searching I realize the truth. So, here I’m going bring the facts the way I told my friend. All Hard Disk manufacturer way of counting space is different from the way a software count a space. This means to a Hard Disk Manufacturer, 1GB is 1000 MB, 1 MB is 1000 KB and so on.Software or computer language recognize a space in terms of power of 2 say 21, 22,23 etc. hence a KB is 210 Bytes which is 1024 Bytes.Lets do a little math:From a Manufacturer a 250 GB hard disk is 250 x 1000 x 1000 x 1000 =250000000000 Bytes From the Computer Language point of view a 250000000000 Bytes is:250000000000/(1024*1024*1024)=232.83 GB. Now you’ll see why your 250GB harddisk has only less than 232.83 GB space in total. !!
