May I ask why the newly bought 160G Seagate Parallel Port hard drive is only 149G after formatting

Because the hard disk manufacturer is 1G by 1000M, and the operating system is 1G by 1024.

So 160g is only 149g

Also, if you're using NTFS format, it seems to take up a portion of the space to store a list of files, making it easier to find files.

My computer is also 160G and it's actually upstairs and it's very right.,1000M is a hard disk-specific setting.,In short, there's nothing wrong with your computer hard drive.,It has nothing to do with the brand or something else.。

Normally, the hard disk manufacturer is 1G by 1000M, and the operating system is 1G by 1024.

When partitioning, the capacity of NTFS and FAT32 is also a little different!

It's an old question, why is this being done, it's puzzling, why isn't there a uniform standard?

Another example is: the size of the monitor screen, said to be 17 inches, you use a ruler to measure the diagonal of the screen, it must be less than 17 inches, it is said that there has also been a lawsuit, but it was said by the merchant"Industry Practice"There was nothing left.

Consumers are played by JS, helpless!

Yes, we use 1GB=1024MB in our daily life, while manufacturers usually do not use 1GB=1000MB computing

It's good to have so much, but you're not satisfied.

Of course, the algorithm is not the same, the smallest unit of hard disk capacity is bytes, let's convert to bytes first, you do the math:

Hard disk manufacturer's algorithm:

120g=(120*1000)mb=((120*1000)*1000)kb=((120*1000)*1000)*1000)b=120000000000b

This capacity is the actual number of bytes on our hard disk, and hard disk manufacturers are all 1000 decimal system, so agree with this.

The algorithm of the operating system is based on the decimal system of 2, which is 1024

Let's take the number of bytes on the hard drive and divide it:

1200000000000)b/1024=(117187500)kb/1024=(

It's also normal for yours to be 108g, don't believe you to ask a friend with the same hard disk capacity as you, each hard disk is nominally 120g, but it's not the same, the capacity is different, because the hard disk is very large when it is produced, for example, yours is a 120g hard disk, it may be 160g at the beginning of the factory, but there are bad tracks in it, and the manufacturer will store those tracks in a permanent chip, so that the hard disk can skip those places when used in the future. Set aside the tracks that can be used, and calculate the capacity is the nominal capacity pull that we see now. The larger the capacity of the hard drive, the worse it is.

Hello, it may be caused by your mistake, try to reformat the partition with DiskGenius and see if you can restore the normal capacity:

Step 1: We first open the DiskGenius software, then we can see the hard drive that is currently displayed, we choose to delete the partition.

Step 2: After we click on the delete partition, a prompt will pop up for us to confirm whether the hard drive data can be deleted, and we can select Yes.

Step 3: After we have deleted the partition, select the New Partition menu above DiskGenius.

Step 4: We can set the hard disk in the pop-up partition familiarity, such as 4K alignment, etc., and then click OK.

Step 5: Once the partition is complete, we click on the Save button on the top left of DiskGenius.

Step 6: The newly created partition needs to be formatted, after we click Save, select Format, and then our hard drive will become a new state.

Why can't you install it? If it doesn't work, repartition and reinstall. However, I found that the system with ghost will not be installed in some hard disk partitions, and I heard that it is okay to reformat the whole disk and repartition.

Take a slow-loading plate, try it, and you'll definitely be able to do it.
