Why is my hard drive missing nearly 10G space?

At this time, it is caused by some file fragments on the hard drive, which are invisible, and you can use a defragmenter to organize them, or you can format the hard disk, and the less space will come back.

How do you know only 10gYou may be mistaken. Maybe you're overthinking.

Then you format your disk to see the line, generally speaking, it should be okay!!

The actual capacity of a 1T hard drive is about 931G.

In the process of using the computer, we may find such a phenomenon, why is it a 40GB hard disk but only about 37GB is recognized in the operating system system, an 80GB hard disk is only 74GB, and a 160GB hard disk is only 149GB, and the difference between larger capacity hard disks is 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 disk manufacturer's standard: 1GB = 1,000MB 1MB 1,000KB 1KB 1,000byte

Operating system algorithm: 1GB = 1,024MB 1MB 1,024KB 1KB 1,024byte

This calculates the hard drive manufacturer's 1GB 1000 1000 1000 (1024 1024 1024) in the Windows operating system.

Hard drive manufacturer's 40GB 40 operating system.

HDD manufacturers 80GB 80 operating system.

Hard drive manufacturer's 120GB 120 operating system.

HDD manufacturer's 160GB 160 operating system in 149GB

HDD manufacturer's 200GB 200 operating system.

HDD manufacturer's 250GB 250 operating system.

And so on. Your 1TB is exactly 1000GB, and the actual calculation is 931GB is normal.

Summary. 1. I'm not sure what the specifics are.

2. If you sell a class such as a 1T hard disk, it is normal to have a 30G less.

What to do if the hard disk memory is less than 30 g.

1. I'm not sure what the specifics are. 2. If you sell a class such as a 1T hard disk, it is normal to have a 30G less.

It used to be more than 1890 G, and now it suddenly becomes 1863 G, and now it can't be recognized on the computer, and it shows unallocated after entering Disk Management, how to solve it?

How to recover partitions and files with DiskGenius.

Let's go and learn, supposedly there is a problem with the partition table.

It's just which one to press.

**Learn the content yourself.

This software is only used after honest study.

Is there any other way besides this method? He has a save change that costs more than 200 yuan, but more than 200 yuan can buy a hard disk.

You can find a cracked software to try it. Actually, I use these software are cracked versions.,Supposedly, the cracked version shouldn't have this thing.。 Because these software are almost only used at the time of installation.

Usually rarely used, only know that the problem is found, and there is not much practical experience, because almost never encountered! And there are a lot of these similar software, the owner can't find the west, you can take the time to search for it.
