RE: 2.4: "access beyond end of device" after ext2 mount

[Piszcz, Justin Michael]

Normally, this problem associated with drives over 32GB or 127GB on a
controller that cannot support it.  It was not discussed here, I was
wondering if that is the problem, if it is not, what type of Hard Drive
is giving you these problems?

Thanks.

OK.

This seems to be harmless, so, better do nothing about it.
