I don't think so.

The result is:

D:\coLinux>dd.exe if=\\?\Device\Harddisk0\Partition4 of=foo bs=512 count=1
rawwrite dd for windows version 0.5.

Same for the HarddiskVolume4 partition, and also for the Partition 6.
On the other two partitions, it works fine:

D:\coLinux>dd.exe if=\\?\Device\Harddisk0\Partition5 of=foo bs=512 count=1
rawwrite dd for windows version 0.5.

This means that Windows can access the two partitions of type 0x83 (Linux),
but refuses access to type 0x8e (Linux LVM).

While coLinux is running, none of the partitions can be accessed, but the
error messages are different:

(Type 0x8e Linux LVM)
D:\coLinux>dd.exe if=\\?\Device\Harddisk0\Partition4 of=foo bs=512 count=1
rawwrite dd for windows version 0.5.
