How to write data to sectors of a USB drive?

Question

Windows

Hello everyone, I need to write data to sectors of a flash drive and I ran into a problem when there is an unallocated area on the flash drive at the end, I have no problems, but if there is no such area, that is, the end of the physical disk co-flows with the end of the logical one, then when I try to write data, for example, to the penultimate sector from the end, I get a stable ACCESS_DENIED error. Does anyone know how to get around this? 7/8/10 system. Or maybe you can get some kind of privilege that will allow you to do this?
