Did you do that as root?  All of my windows disks report valid
partitions.

From my sever:
% fdisk -s da0
/dev/da0: 2231 cyl 255 hd 63 sec
Part        Start        Size Type Flags
   4:           1    35841014 0xa5 0x80

From my laptop:
fdisk -s ad0
/dev/ad0: 559 cyl 240 hd 63 sec
Part        Start        Size Type Flags
   1:          63     2766897 0x0b 0x00
   2:     2766960     5397840 0xa5 0x80
   4:     8164800      272160 0xa0 0x00

I'm in group operator, so I can read the disks on my own.  The part
type 0xa0 is for the suspend to disk partition in my VAIO.

: Does that mean that a dedicated disk has a slice table, a normal doesn't?

No.  That's backwards.  A dedicated disk has no slice table (a
dangerously dedicated disk, that is), and a "normal" one does have a
slice table.
