    Hard drive is not showing correct amount of space?

    Issue:

    Hard drive does not show the exact size what it is rated for i.e 1TB = approx 931GB


    Resolution:

    This variation in size is caused due to the fact that Hard drive manufacturers uses the decimal system to measure the HDD capacity.

    In a decimal system "1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 Byte"

    Where as most OS calculate in binary i.e 1024 instead of 1000 "1 GB= 1024 MB= 1024 x1 024 KB= 1,073,741,824 Bytes". Thereforeall drives seem to be around 1.074 times smaller under the operating system than there actual size.

    For example: An 1000GB = 1TB drive can store 1000,000,000,000 bytes, but the operating system divides this number by 1.074 and therefore shows the drive as having a capacity of 931.1GB only. You are still storing same number of bytes in either case.
