As it turned out, the write protection mode turns on spontaneously on all flash drives from SanDisk. On the website of this wonderful manufacturer, where I went first of all, it is written that their miraculous chip itself determines in which cases to protect the flash drive from writing, and no one is able to remove this protection later, even the manufacturer himself. I was lucky - it stopped working on the first inclusion. But if I bought it, for example, in another city, in a closed kiosk, or simply lost the check, a thousand would go to the trash. It was my first and last flash drive from SanDisk.
