How?
In FreeBSD terminalogy this is now 2 slices:-

In FreeBSD terminology "created partitions" or
more specifically "BSD partitions".

On the first "slice" -- no "BSD partitioning".

The MBR (master boot record) table will still have
the first slice marked as ntfs unless you ran fdisk to
change it.

It seems you have now assigned all "slices" to Linux
at least in your mind. But what types does fdisk think they are?

Probably because it is still marked as ntfs in the MBR.
Change its type with fdisk.

Where is FreeBSD? -- it appeared you had given the FreeBSD slice
ad0s2 over to Linux swap -- but then I'm not knowledgable with
respect to exactly what Linux means by hda2.

What data? -- the original ntfs data or what Linux may have installed?
I suspect that in either case it is now pretty much corrupted. The semblance
of windows files will have a scattering of blocks over written by newfs.

You seem to be confused with slices and partitions -- but it IS
confusing. Just remember Microsoft partitions are slices in the BSD
world.
