System: NetBSD chiharu.yk.rim.or.jp 1.3 NetBSD 1.3 (MOBIO) #0: Mon Feb 2 02:51:32 JST 1998 oki@chiharu.yk.rim.or.jp:/usr/src/sys/arch/i386/compile/MOBIO i386


>Description:
	
	NetBSD can mount and read FAT32 filesystem with msdosfs.
	But, cannot write to FAT32 filesystem. Hang up.
>How-To-Repeat:
	
	In Windows95(OSR2) command prompt,
		FDISK (with large filesystem support)
		FORMAT C:
	In NetBSD,
		(/dev/wd0e == C:)
		mount -t msdosfs /dev/wd0e /c
		mkdir /c/XXXX, touch /c/XXXX, etc, etc.
>Fix:
	
This is patch to NetBSD-current(1.3E, 980420).
