Tools / Raw Materials: Computer U disk

Methods / steps: 1 When copying, it is not completely copied in. Please remove the U disk in advance. Or the copy is not trusted by the anti-virus software, and the anti-virus software is automatically deleted after reporting the virus. When we copied, make sure to copy it to the U disk and then unplug it. If it is a virus report, we open the kill software and go to the recovery area to see if it was deleted by mistake. 2 There is a virus in the U disk, the file is hidden, or the virus deletes the file directly, we open the antivirus software and find the U disk killing function. Kill the USB flash drive, or select a USB flash drive by location. After the antivirus is complete, click Restore or re-examine the file to the USB drive. 3 If the above method is tried and the copy is still not available, then right-click the properties of the USB disk and open to check the disk.

After you have saved 8G files in it, you see that there is still a lot of space left. But how do you copy the files to the U disk, once you unplug it, there is nothing. When you copy it, you can still see the files copied in, but unplug No more plug in. No matter how big it is, it can only save 8G files. 5 At this time, we need to use the USB disk identification tool to identify it. Go to Baidu to download or use the detection tool that comes with the security guard. 6 I have tried the above, but there are still problems, we download the U disk tool to detect and repair it.
