Formatting DS\\DD 5'25 720kb disks on PC

Hello All! Is the subject even possible, since the format is non-standard? If yes, what software? can this be done normally? DOS Navigator seems to format it when finished writes that 720kb is free, then, when the panels are re-read, it displays below, which is free 360kb. When you try to write to such a disk, the computer unwrites the file portions, in between swearing that he couldn’t write something down, but in in the end it records, within 360kb, of course. I heard that supposedly for To support this format, you need a special driver, is that true? I wonder what disks formatted for MS-DOS 720kb on the Spectrum, the PC understands fluently, and writes, and reads, and does not swear, so Specov disks for the emulator using disk2trd are driven without problems. But is it really on the PC for this that it’s normal? there is no software, just as I have never seen or heard of any analogue Spec's DCU-shaped disk recovery utilities? Best regards, Alexey.
