[hatari-devel] Strange problem with Floppy access in Falcon mode & TOS 4.04

[Thorsten Otto <admin@xxxxxxxxxxx>]

Hi,

with hatari built from current source, i encounter some strange floppy disk 
read errors when accessing a normal file image of 1440KB. The root directory 
is shown without errors, i can also open some subdirectories, but when trying 
to display text files, i get read error on some (but not all) of them. Any 
idea what might be causing this?

config file is attached, if that matters.

I'm sure the image itself is ok, since i can access it without errors both 
when running emutos or tos 3.06.
