The USB disk can be recognized on the back of the computer

php editor Baicao reminds everyone that sometimes when we use a U disk to connect to the computer, we may encounter a situation where the USB interface on the back of the computer cannot recognize the U disk. This problem may be caused by a variety of reasons, such as loose interfaces, driver issues, etc. Today, let’s discuss the solution to this problem and help you solve this trouble easily.

U disk is the most commonly used mobile storage device. I don’t know, after you connect the U disk to the computer, when you need to remove it, do you just unplug it directly?

To be honest, when I first started using the U disk, Dabaicai also honestly clicked on the U disk safe ejection option.

However, when I got anxious and the pop-up failed again, I basically pulled out the USB disk out of frustration~

After that, Dabaicai also tried Unplugging it directly after a few times seems to have no effect. So is it really that important to safely eject the USB flash drive?

Here, let’s briefly talk about why there is a “safe eject” option?

In early Windows systems, in order to improve the reading and writing speed of external storage devices, Microsoft would enable caching for these devices.

In short, when you copy data to a USB flash drive, Windows will first write the data to the faster cache and then write it to the storage device. This will cause the computer to first "Copy successful" is displayed.

The reality is that if your cache has not been completely written, if you forcefully remove the USB flash drive, you will be fooled by Windows.

After using a USB flash disk, problems such as data loss, unrecognizable device, and need to format or repair sectors may occur.

Therefore, in order to avoid data suddenly losing its target in the cache, which may cause Windows to slow down and other consequences, Microsoft has added a safe pop-up function.

Purely from the nature point of view, safe ejection is just a detection process to check whether the data in the external storage is being read or written. It has little technical content. Strictly speaking, it is different from direct plugging and unplugging. Very small.

However, the quality of previous USB flash drives varied. If your USB flash drive manufacturer did not follow the protocol when manufacturing it, that is to say, USB naturally supports hot swapping, which allows users to operate without shutting down the system. Remove the hardware without cutting off the power supply.

The consequence of casual plugging and unplugging is that the U disk hardware is easily damaged, and eventually the U disk is scrapped~

There is a reason why U disks from serious manufacturers are expensive~

Nowadays, U disks are developing rapidly, the reading and writing speed has been increasing, and most U disks support hot swapping.

Microsoft has finally realized that a change is needed. After version 1809 of Win10, all Windows computers will support U disk hot swapping by default.

So, in addition to reading and writing operations, the external U disk can be removed at will by default! The previous statement of caching will no longer exist. If the data is said to have been transferred, it has been transferred.

It should be noted that Microsoft’s technical improvements this time are only for U disks, so if you are connecting an external mechanical hard disk, it will be safer to “safely exit” (due to the structure of the mechanical hard disk) .

However, there is also a saying that Microsoft's "Quick Delete" sacrifices the performance of the U disk to ensure the safety of the U disk. When the U disk is inserted, Windows cannot cache the disk write operation. This can be understood as Less performant and slower, but can be plugged and unplugged at will.

Recently, many friends have reported that the U disk transfer speed is slow, precisely because of this reason.

Therefore, some friends still insist on Microsoft’s previous settings for the U disk, which prefers the “better performance” mode. The file opening speed is fast and the transfer speed is also fast. The U disk is on standby at any time, but it must be clicked. "Safely Remove USB Hardware" will stop the USB drive from working.

Of course, you are free to choose the method to insert and remove the USB flash drive, but the current version of the window system has modified the settings.

If you want to manually remove the hardware instead of plugging and unplugging it directly, you can still set it up:

1. Insert the U disk into the computer, right-click the U disk, Select Properties

2. On the page, click to switch the "Hardware" tab, and then click "Properties"

3. Finally, you can set the policy to enable, Click "OK" to save the changes, and then you need to "Safely Remove Hardware"

This time about the issue that the U disk must be ejected safely and cannot be plugged in or out at will. The answer given by Microsoft is, Are you still satisfied?
