whitch partition format linux and windows are allowed to write on fat32 or ext2?
Linux can write to both FAT32 and EXT2 along with many other file systems. My computer can boot to both Linux and Windows. The Linux partitions are formatted EXT3. I also have a partition that is shared by both Linux and Windows that is formatted FAT32. I can write to the FAT32 partition from both operating systems.
In order to be able to write to the FAT32 partition, I had to add "umask=000" on the proper line in /etc/fstab thusly:
/dev/hda3 /D vfat defaults,umask=000 0 0
Of course, your hard drive partition is probably not /dev/hda3 and your mount point is probably not /D, so you will have to supply these parameters based on your computer's setup.
