The other night at golf league one of the members was commenting on how he ordered a new computer and “upon delivery the hard drive was reported as 20gb less than what the size on the website” had advertised. He was supposed to have 160gb hard drive, but when Windows was installed and the drive was viewed for available space it showed around 149gb. With the hefty Windows install, the drive was down close to 125gb. I had a good idea of what was going on as far as interpreting what a hard drive truly consisted of and how the computer interpreted it. A quick Google search pulled up some forum debates and a few good articles. Tech Support Guy Forums has a member that gave a pretty straightforward answer.
That’s right. That is the true amount of space on a one terabyte drive. The manufacturer’s use 1000 kb as one MB, rather than 1024 kb.
