In contrast, Windows and other operating systems use binary (base 2) notation. This is why, for example, that a HDD labeled and sold by the manufacturer as 76.86 GB is reported by Windows as 71.6 GB. NOTE: Always convert like units to like units, e.g., decimal GB to binary GB, or binary GB to decimal GB. To convert decimal kilobytes to binary kilobytes multiply by .976563 1000 / 1024 = 10^3 / 2^10 ~ .976563 To convert decimal megabytes to binary megabytes multiply by .953674 1000^2 / 1024^2 = 10^6 / 2^20 ~ .953674 To convert decimal gigabytes to binary gigabytes multiply by .931323 1000^3 / 1024^3 = 10^9 / 2^30 ~ .931323 To convert decimal terabytes to binary terabytes multiply by .909495 1000^4 / 1024^4 = 10^12 / 2^40 ~ .909495 To convert in the other direction, e.g., binary units to decimal units, multiply by the reciprocal (multiplicative inverse). To convert binary kilobytes to decimal kilobytes multiply by 1.024 To convert binary megabytes to decimal megabytes multiply by 1.04858 To convert binary gigabytes to decimal gigabytes multiply by 1.07374 To convert binary terabytes to decimal terabytes multiply by 1.09951 __________________ __________________

The shelves in your empty room take up some space in the room, the same way with the file system on a hard drive, the "shelves" for the data take up some of the room on the hard drive, so thats why it's reading only 195 gb or whatever, because of the file system taking up room on the drive like on my primary hard drive, I have a partition for my os and progs, which is 50 gb, it only shows at 48.8 gb, and I have the rest as another partition which is 150 gb, but it shows as 141 gb. and my 250gb drive is showing at 233gb, which leads me to believe that the bigger the drive the more space you lose. you can't have your cake and eat it too, windows doesn't work like that.....lol __________________ When all else fails...Ham Radio!
