Why 1TB external disk only showing 931GB in Windows?

I bought a 1TB external USB drive, but it only shows 931 GB in Windows 7.
This is due to that  drive manufacturer count TB in different way from Windows.
For Drive manufacturer:
1TB=1,000,000,000,000 bytes
For Windows:
1KB=1024 bytes
i.e 1GB=1073741824 Bytes
931GB= 1,000,000,000,000 bytes

So drive manufactures do not cheat us, but misleading. The definition in Windows is closer to the definition in computer science.
