Tony, thanks for the reply. Someone else has figured out that my
partitions are overlapping. Oh, and I am using the term partitions
as BSD uses them. In the BSD world you can have four slices and
each slice can hold up to 8 partitions (what the BSDers call
slices is what the rest of the world calls partitions and what you
call UFS partitions). I had made the same mistake and was corrected
by a couple of the FreeBSD developers. Now this gets confusing,
even in the man pages. For example the man page for fdisk talks
about partitions, but that is because the DOS calls them this. At
the bottom of this page it says:
Throughout this man page, the term `partition' is used where it
should
actually be `slice', in order to conform with the terms used
elsewhere.
at least on the 2.1.0 release.
So for FreeBSD a slice = a DOS partition and a partition seems to be
equivalent to a DOS extended partition.
I will check my disk with SCANDISK (if I can do so without clobbering
everything I'm trying to save). Thanks again for the suggestion.
