Why is the capacity of the USB flash drive insufficient, and why is the capacity of the USB flash dr

In fact, this conclusion should be incorrect, or depending on the specific problem, let's analyze it for you: Because the U disk manufacturer is calculated according to the conversion unit of 1g=1000m, and the computer is calculated according to 1g=1024m, so the actual capacity of the U disk with a nominal 8G capacity on the market is only 8*1000=8000M, not 8*1024=8192M as we understand it. In this 8000m capacity, divide 8000m by 1024m g (computer) =, and then deduct some system files to occupy the space that may be left, so the 8g**u disk you bought, the capacity displayed on the computer is not 8g, generally floating left and right.

This situation generally appears in the storage industry on hard disks, USB flash drives, ***, MP4 and other storage products, the principle is basically the same, because these products have hidden partitions, used to support hard disks, USB flash drive boot and ***, MP4** and other special functions.

Solution:1 After the USB drive is plugged into the computer, right-click on the USB drive icon to check the attributes.

2 Right-click on the icon to enter formatting.

Remember to back it up first.

There is a part of the space in the USB flash drive that is not allocated, resulting in the problem of the capacity of the USB flash drive becoming smaller, which can be solved by the DiskGenius software, and the steps today are as follows:

<>5. Right-click the gray part above the software, click the Assign Free Space button in the submenu, and then select a drive letter in the submenu to allocate the free space.

6. After completion, exit the software, restart the computer, and you can see that the capacity of the USB flash drive has been increased, and the free space has been allocated, and you are done.

It's a virus, and the solution is as follows:

1. First, return to the computer desktop, use the shortcut key win key + R to call up the running window, enter cmd, and click the enter key.

2. Enter chkdsk ?Click Enter to see all the functions associated with the command.

3. Try to fix the error of the disk to fix the USB flash drive, enter chkdsk h: f, where h: is the drive letter of the USB flash drive, and click the enter key.

4. Finally, wait for it to check and repair the U disk, and after the repair is completed, as shown in the figure below, the problem will be solved.

It's not that it's not enough, but the algorithm is different, people are 1024, we are 1000. Here is a simple practical problem, when you buy a hard disk, such as 160GB, the base system used by the manufacturer here is 1000, not 1024, so after 160GB formatting, it is probably only: (160 x 1000 x1000 x1000) 1024 1024 1024 = 149GB

When the USB flash drive is plugged into the computer or other equipment, the power on starts to work. As an electronic device, the USB flash drive will consume electrical energy during operation, so it will inevitably release heat, which is what we usually call heating. Generally speaking, as long as the temperature of the USB flash drive is not abnormally high, then it is normal.

If the temperature of the USB flash drive is particularly high, and you can even feel the heat obviously, then such a heat is very abnormal. Generally speaking, the temperature that the chip inside the USB flash drive can withstand is about 85 degrees Celsius, and if the USB flash drive is at this temperature for a long time, it is very likely that the USB flash drive will burn out. Once the USB flash drive is abnormally heated, it is recommended that users replace the USB flash drive or back up data as soon as possible to avoid data loss.
