u want to format the FAT fs and get a ext2 or ext3?
u just use fdisk /dev/hdxy to get the device number of the fat u want to format
then mkfs /dev/hda3 (if u find that hda3 is u fat partition)
ths is not related to kernel.
i have already format my /dev/hda3 to FAT16
now what i have to do is to operate on this region of hard disk using my own filesystem.
and the read_file, create_file, and write_file have already existed, now i am doing delete_file, and format function. i dont know how to begin!?
so depressed!!
