Summary	08779: Apple IIe, probably all Apple II models: Apple IIe floppy disk creation is buggy/broken. Cannot write to floppy disk
Description	Tried running Zork III Release 17 Interpreter K on Apple IIe. Game itself runs fine. But disk creation and saving is bugged. Reading from disk is fine, just not writing Tried to save my progress in game. Expected behaviour Zork III should say "Ok." and should be able to restore from disk created in MAME What happened was it crashed.
Steps To Reproduce	Loaded apple2e driver loaded zork3.zip (contains .woz disk image) game boots and plays fine game needs a disk to save progress to create new WOZ disk in 2nd drive slot, restart system walk around then save in Zork 3 "Failed" if I use another format like DOS or ProDOS, MAME refuses to even attach the disk image to 2nd drive slot I used a blank .nib disk file from the internet which I then saved in Zork 3 in the AppleWin emulator. Then I loaded this .nib file into MAME and was able to restore my progress. But saving to the .nib in MAME would say "Ok." (even though it didn't save) and then restoring from it after would crash with Internal Error 14.
Additional Information	Also tried in MAME 0.258. same problem

When you create a blank image in MAME, you get an _unformatted_ floppy, whereas, according to the Infocom Reference Card, you need a formatted floppy to save your game. The second half (where saving to an existing floppy disk appears to succeed, but then loading crashes the game) does appear to be a MAME bug, though.
