Hello Kern,

Hello Radosław,

There may be a place for an option that puts back zeros where zeros were
read as Bastian is requesting,

This is a good idea. I suggest that this option should be set to the current behavior on default.
but it is clear that this code would break the
current behavior of sparse file (sparse volume) handling, which is not desirable.

I agree.
Best regards
Radosław Korzeniewski
