Thumbs up which daemon or program watches writing files on floppy disk?


Hello folks,

I got two redhat8 systems. I found that I could write files to the floppy without umounting the floppy disk on one of them. That means when you copy a file to the disk, it writes on the disk right away. but another one got a problem on this. it will lose the files if you don't umount the disk. I failed to find out the
difference between the two in terms of writing files on floppy disk. Does anyone know which program or daemon is to watch or control writing files on
floppy disk?

check out mtools, it seems it has a 'dos' like way to handle writing to a floppy

lost floppy files

Linux uses a disk cache. When you write to a floppy or a hard disk the buffers are first entered into the disk cache. Later the cache buffers are writen to the floppy or hard disk. If you take a floppy or hard disk down without doing an umount you may or may not lose the data depending on whethe the data happens to have already been written.

When you do an umount one of the things that umount does is writes all of the cache buffers to the device before dismounting it.
