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

Is this still a problem with latest git?

Just tested with mame-windows-gcc-c7967fdd59c85b3a548e2d19bce5da255e937432

unfortunately this problem is still here, can't save or restore from floppy disks, no matter what format (WOZ, DOS, ProDOS, MFI)

FWIW, I think the first half of this report is not a MAME bug. 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.
