Hard Drive Size Mismatch??

post #1 of 9
Thread Starter 
I have a 100gb 7200 rpm HD in my laptop. It is corectly listed in the bios and in everest ultimate edition has a 100gb hard drive.

But in windows, it tells me that my max space is 93.1 gb.

Why is that so?????

Operating systems frequently report capacity using the same abbreviations but with a binary interpretation. For instance, the prefix mega can also mean 220 (1,048,576), which is approximately 1,000,000. Similar usage has been applied to prefixes of greater magnitude. This results in a discrepancy between the disk manufacturer's stated capacity and what the system reports. The difference becomes much more noticeable in the multi-gigabyte range. For example, Microsoft Windows reports disk capacity both in decimal to 12 or more significant digits and with binary prefixes to 3 significant digits. Thus a disk specified by a disk manufacturer as a 30 GB disk might have its capacity reported by Windows 2000 both as "30,065,098,568 bytes" and "28.0 GB" The disk manufacturer used the SI definition of "giga," 109 to arrive at 30 GB; however, because the utilities provided by Windows define a gigabyte as 1,073,741,824 bytes (230 bytes), the operating system reports capacity of the disk drive as 28.0 GB.
thats why

1MB = 1024kb
HDD makers say 1MB = 1000kb

You lose space.

Yup. Everyone's the same. Even USB Hard Drives works like that.

I thought it was because Windows: XP takes up a certain amount of space... So, if you have a 40GB Hard Drive and you install the OS you only have like 38.6GB or whatever left...

Thanks guys.

No, the formating and MBR does take up a little space. OS reports back what space it does use.
Once again...
