Hard disk storage capacity not in line with nominal value is it a lie?

Generally speaking, the size of the hard disk is less than the nominal value, which is due to different conversion methods.

Hard disk manufacturers generally according to 1MB=1000KB to calculate, and in most computer BIOS and test software are calculated by 1MB=1024KB, so that the capacity between the two differences, but the actual capacity and nominal value of the gap will never exceed 20%.

If the gap between the two is very large, you should enter the BIOS setup at boot time, and according to the hard drive for reasonable settings.

If not, it may be that the motherboard is too old to support a large-capacity hard drive, and you can try downloading the latest motherboard bios and refreshing it, most of which occurs when a large-capacity hard drive is paired with an older motherboard.

In addition, due to sudden power outages and other causes of the BIOS setup confusion may also lead to this failure occurred.
