I made the USB flash drive into NTFS format to prohibit write permissions under the root directory. In this way, many USB flash drives cannot be damaged. But today, I accidentally pulled out the USB flash drive when there was data, and the folder was displayed, but I was prompted to reference an inaccessible location. I thought it was miserable, and there was a lot of data in it. I went online to find various NTFS repair tools.
While thinking that Windows does not have chdisk, right-click the USB flash drive on my computer and choose Properties. There is a tab "tool" in it ", click the first "check error" to start the check, and check to automatically fix the error. The check will be completed in less than one minute and re-opened, and the folders will be accessible again.
Originally, NTFS is much less prone to errors than fat. This error is caused by the sudden unplugging during reading and writing. It is inevitable that there will be a small problem, but it can be fixed...
However, we recommend that you back up important data. Even if NTFS is safe, there will be other problems, such as losing it (haha, pp)
