My hard drive is 80GB why is it only 76 1GB big now

Big brother, after the hard disk partition will "waste" some vendors' tricks, using different conversion methods:

Manufacturer: Decimal 1000m 1g, 1000k 1m, 1k 1000 bytes.

Operating system: binary, 1024m 1g, 1024k 1m, 1024 bytes 1k

And so came the result:

The units of calculation are different, so the display is different. Hard disk manufacturers use decimal 1000m 1g, 1000k 1m, 1k 1000 bytes, windows use binary, 1024m 1g, 1024k 1m, 1024 bytes 1k. So the standard 80G hard disk should display a little more than 74G, and your hard disk should be Hitachi, which is usually a little larger than other manufacturers, so it is to display 76G

Normal What brand of hard drive?

Remember 1m=1024kb, right?

The conversion unit of the windows system and the manufacturer is different! That's why this happens!!

It may be that you didn't divide it well when you partitioned, find a software to check it!

If it's the problem of the hard drive itself, you can find a seller to change it to you!

It is also possible to submit to the consumer association.

The hard disk is carried by 1000, but the system is carried by 1024.

Converted in kb.

This is because System Restore will take up space on your hard drive.

Quite a little bit is not normal! The problem of conversion. Don't worry.

Does this need to be asked? Do you have more than four districts?

Too much useless, really can't get things done.

That's not a dime!

This is a normal phenomenon, as long as it does not exceed a difference of 10g, it is normal.

What was said upstairs made sense.

I would also like to add that hard drives are subject to low-level formatting before leaving the factory, which will inevitably lose some pull

Mine too, this is normal, you go and look at those, *** is the same, 128 is actually no, 128, almost between 120 and 125, don't believe it, ask.

An inevitable phenomenon after partitioning! You have to throw away the skin when you buy watermelon to eat!

The size of the hard drive is not very standard.

It's normal.,It's just ordinary 8G memory like this.。。 Buy back only 7g more points,. It also has something to do with the manufacturer of this thing. The better ones will have a little more memory. And the transfer speed is faster.

Normal, it's genuine, and USB hard drives are like this.

Normal, as cache partitions take up a portion of space.

The conversion rate of the hard disk manufacturer is 1000GB = 1TB, and the system conversion rate is 1024GB = 1TB

It's normal, it's okay, have you seen it?

The nominal capacity of the portable hard drive is 2TB, and the actual viewing capacity is normal. There are a few main reasons for the capacity reduction.

1. The error caused by the difference between the nominal capacity and the operating system of the hard disk manufacturer and the difference between the two is different. When the hard disk manufacturer calculates the nominal capacity, it is based on the decimal method: 1KB=1000bytes, 1MB=1000KB, 1GB=1000MB, 1TB=1000GB; Whereas, the operating system calculates the capacity in binary terms:

1kb=1024bytes、1mb=1024kb、1gb=1024mb、1tb=1024gb。Therefore, the actual capacity seen in the computer will be different from the capacity of the manufacturer's trademark.

2. When the hard disk leaves the factory, it will be written into the manufacturer information, hard disk information, firmware and other files, which will also occupy a part of the capacity space.

3. For mobile hard disks, a small part of the capacity space will be used as a ** station to store deleted files.

4. Start boot partition and the existence of bad blocks occupy a part of the capacity space.

In the process of using the computer, you may find such a phenomenon, why is it a 10GB hard disk but only about 9GB is recognized in the operating system system, a 20GB hard disk is only 19GB, a 40GB hard disk is only 38GB, and the difference between larger capacity hard disks is even greater?

This is because the hard drive manufacturer's definition of the hard drive capacity and the operating system's algorithm for the hard drive capacity are different, resulting in an error between the disk identification capacity and the actual capacity displayed in the operating system.

Let's compare the criteria of the two and actually do the math:

Hard drive manufacturer's standard:

1gb=1，000mb 1mb＝1，000kb 1kb＝1，000byte

Algorithm of the operating system:

1gb=1，024mb 1mb＝1，024kb 1kb＝1，024byte
