Your message isn't well explained, so my answer might not be correct,
but I'll explain as best I can and see if it answers what you're asking.

The first 63 blocks and last 4725 blocks are unused because you're using
a DOS parition scheme. I don't know the details of why DOS partition
schemes waste this space, but they do.

When I say, DOS, I mean any version of Windows as well, since they all
use the same partition scheme.
First thing to understand is that what BSD calls a "slice" is = to what
DOS calls a "partition"
What BSD calls a "partition" doesn't really exist in DOS, BSD partitions
exist inside BSD slices. If that's not confusing enough, I don't know
what is. From here on out I will use BSD terminology for clarity

The First slice is your C:, looks like it's about 6G or so and it's
formatted FAT (DOS filesystem)
Second slice is your D:, it's an "extended partition" (no information
about format) and about 3G or so in size.
If you want to delete the C: slice and replace it with FreeBSD, do this:
use the down arrows to highlight the FAT slice and hit the "D" key to
delete it. Then scroll back up to the top of the screen (where it says
"free") and hit "C" to create a new BSD slice. (choose type BSD) Use all
the space it will allow. You should now see something similar to what
you saw before, except the first slice will be labeled "FreeBSD"
Now you're done with this screen. press "Q" to exit.
You'll next enter the partition editor, You want to create all your
partitions on the first slice. Use "A" to auto-create default size
partitions - read up about what each parition is for so you better
understand what each is used for, but for now the defaults will be fine.
When prompted, select "booteasy". booteasy will allow you to select
which OS to boot as the system is starting.

Warning! There's an outside possibility that the OS on your D: drive
will be unbootable after this (unlikely, but possible) so make sure
you're serious about not having any important data that could be lost
before continuing.

Hope this helps.
Bill
