Why real capacity of WD external hard drive are messing? it’s lost 70gb?I’m no computer expert, but every drive is like this. For example, a 32 GB iPod will come with only around 30 GB free and a 120 GB Xbox 360 hard drive will come with about 110 GB free. It’s just how memory is, nothing is wrong with your drive. In the grand scheme of things, 70 GB is smaller than either of these examples in terms of percentage.
For marketing purpose, 1TB (terabyte = 1,000,000,000 byte). In computer world, 1KB=1024Bytes, 1MB=1024x1024Byte, and 1TB=1024x1024x1024. That means whenever you get a hard drive, it will never be the “marketing size” once you see it on computer. What you see on computer in this case = 1,000,000,000 / 1024 / 1024 / 1024 ~= 0.931TB which explain why you think 70GB are missing.
Actually, you haven’t lost anything at all. It’s all still there, and you are able to use all that it came with. The confusion is coming about because WD has defined a terabyte as 1 trillion bytes of data, although this is NOT the same as a true terabyte. It comes with 1,000,169,533,440 total bytes of space available. This equates to 930 GB in technically-accurate computer terms.
