whats the command i put in the file explorer to go from linux (hdb) to windows 98 (hda) i did it before,but i forget the command 
Should be something along the lines of :
mount -t msdos /dev/hda /mnt/point
That didnt work! any other ideas ??
What part didn't work?
Error messages?
it just said not a vailid drive command
What OS? Please provide the `uname -a` output, thanks.
try using "mount -t vfat /dev/hda1 /mnt/win98 (or whatever directory you want)". I also make sure the mount point exist and also you mention typing the commands into the file explorer.By this I assume you mean konqueror,galeon,etc.These commands should be typed in the terminal.
okay, thanks
