Hard drive missing space

post #1 of 5
Thread Starter 
I notice that whenever I install a new hard drive, some of the space disappears. For example, I have a 1TB hard drive but my computer only says I have 931GB.... Similarly, I have a 500GB hard drive but my computer says its 465GB.... Lastly, I have a 300GB hard drive but my computer says its only 296...

Where is my missing 100+ GB.....

I believe its because there is software on the harddrive already to run the harddrive...

The drive manufacturer is counting what constitutes a TB in a different way than Windows does, using a factor of 1000 instead of 1024.

1,000,000,000,000 bytes
/ 1024 = 976,562,500 kB
/ 1024 = 953,674 MB
/ 1024 = 931 GB

A "proper" TB = 1000 GB would be 1,099,511,627,776 bytes.

This is standard practice for storage manufacturers.

People commit crimes through guns. And guns enable them to commit "higher levels" of crime... Similarly, people do commit errors through pencils, but pencils are not controversial because errors do not hurt anyone.... Nice job at reducing murder, and accidental deaths to spelling mistakes though....

Try this one on for size... "Missiles don't kill people, people kill people".... According to this kind of logic, people should be equipped with nuclear arsenal.. With a background check of course.....


Anyways, thanks everyone for the explanation on hard drives....

I used to wonder this, back when I had a 80GB hard disk it only came up as 74GB. I always thought there was a problem with it lol. Glad I learned since then.

It's the same for me OP, I have 2x 1TB hard disks in my computer and both of them show up as 931GB.
