I don't know a lot. Probably by going into vm86 mode, there you can write to your disks, or else you'll need to write your own drivers.

Ya, I mean I need help to write a driver or routine that allow me to write to a disk or floopy

I suggest write your own. The documentation for these devices are readily available on the internet.

You can use dex OS floppy driver commented to go with the intel pdf manual.
Coded in fasm.

It will just need link into you timer and floppy irq.

For hdd see here: http://www.osdev.org/phpBB2/viewtopic.php?t=12268
But it more the fat part that you will have problems coding, not as in hard, but more as in time.
