There is. (or rather will be. I think it might be in the pipeline).
if you want to check it check
http://pinus.tt.ltu.se/~baf/dkoll.tgz
dkoll.c is cygwin source the rest is visual studio
build by make dkoll
dkoll.exe is the compiled cygwin version which gives on my system:

$ ./dkoll
Disk 0  cygwin=/dev/sda
dsig a853000400000080
Disksize 18GB
 part    len typ

Disk 1  cygwin=/dev/sdb
dsig a05f20122a744c01
Disksize 74GB
 part    len typ
    1   54MB 222 Dell system          Dell 4.1
    2   59GB   7 NTFS                 NTFS
    3  502MB  12 FAT 32 (xp)          MSWIN4.1
    4   13GB 131 Linux Native         ext3 LILO
    5  996MB 130 Linux Swap           SWAP

Disk 2  cygwin=/dev/sdc
dsig c282801c8e9ce5bf
Disksize 115GB
 part    len typ
    1  115GB 131 Linux Native         XFS

Disk 3  cygwin=/dev/sdd
dsig f99e600d8e82ca7b
Disksize 55GB
 part    len typ
    1   55GB   7 NTFS                 NTFS

Disk 4  cygwin=/dev/sde
dsig 7de080005cf52c49
Disksize 2.0GB
 part    len typ
    1  2.0GB 131 Linux Native         ext2

baf@bafstat3 ~/dkoll
$
so you get windows disk number. cygwin /ev/sdX disksize and partition size
plus a good guess of what filesystem it has. NOT always perfect.
The partition number is the the same as Y in /dev/sdXY
Hope this helps.
