Why is the newly bought Hitachi 320G mobile hard drive only 298 points more than G?

Normally, hard disk manufacturers are based on 1000 base, that is, 1GB 1000MB, 1MB = 1000KB, and so on. But when formatted, it is calculated as 1024, which is 2 to the 10th power. So 1g = 1024m, 1m 1024k.

From this, the 320g one is indeed just that.

You see if there are any redundant hidden files. Open My Computer - Folder Options - View.

Put the content color of the display system filer.

Remove the checkmark that hides protected operating system files.

The following items are Hidden Files and Hidden Folders. You choose to show all files and folders.

If it still doesn't work. Format him again!

Normal,There must be a formatted space, if you buy it320G,It's either fake.,Or virtual memory.,U disk is the same.。

Hangzhouers is exactly right, these are two standards in the two industries, the capacity carry is K in both hardware and software, but in the hardware industry 1K 1000, in software (operating system, etc.) 1K 1024, the above units are bytes. Then the hardware has 1G capacity of 1,000,000,000 bytes, and the software thinks it is (1024 1024 1024) bytes, then, the formatted space (in G) of your hard disk is:

320，000，000，000）÷（1024×1024×1024）＝ g

It should be fine, mine tried it too.

1.You can also choose the FAT32 format, but the NTFS format is better2Without this statement, new systems such as Win7 must run on NTFS formatted hard disks.

3.The number of partitions should start from the convenience of management, choose the appropriate number of partitions, and FAT32 does not support large files over 4G, so what format to divide into, think in advance.

4.For the new hard disk, right-click on my computer, enter the disk management to partition, and you can also go to the Internet to find partition software, a lot.

Whether it is formatted or not, it depends on what files you use to store, and the format of FAT32 cannot store a single 4GB file. If you want to import such a large file, you need to format it in NTFS format.

As for whether it is divided or not, it is a personal preference. If you want to partition, you can also do it under Windows, as follows:

Plug in your external hard drive.

My computer - management - disk management, can be directly operated, graphically.

As long as you can open the portable hard drive, you don't need to format it. Depending on your personal needs, you can divide it or not.

Portable hard drives? There is no need to partition.

This sound is the sound of the head bouncing off the platter back to the berthing area when the hard drive is powered off, which is completely normal.

When the hard disk is in use, the head reads and writes to the platter where the data is stored on the hard disk through a swing arm, and the head is not attached to the platter, but operates at a height of a few microns above the platter. If the head still stays in the platter area after the power is off, then the head will inevitably stick to the platter, and the data on the platter is likely to be damaged when the next power is started, so the head should be reset when the power is off, and the swing arm will move the head back to the head berthing area outside the platter. You don't have to worry.

The sound when the motor is powered off, as long as there is no sound during normal use, it is fine, so feel free to use it.

Mine is the same, I can't get on the electricity for a long time, and I'm tired to death.

It's not easy to divide? Your hard drive is new, and there will be no data in it. It is now a partition.

Right-click on it and click Delete Partition. After deleting this unique partition. Right-click on it again and click New Partition.

It's just strange that even if it's a newly bought hard drive, why is there already a partition in it?

Right-click on the portable hard disk - Delete Volume - Create Volume - Determine the size, so that the primary partition is created.

If you want to create a logical partition, run -cmd-enter, diskpart-enter, list disk

Select which hard disk to move, select disk (number), creat partition logical, and then exit the hard disk management to continue the partition.
