sdelete may be the easiest, but not the best tool here, since it`s made for
secure deletion and not made for filling a disk with zeroes quickly.
i have no windows around here for performance testing, but dd may perform
better:

You can reclaim this space with the SDelete utility from Microsoft.
With the -c option it will zero any free space on the volume. For
example:
C:\>sdelete -c C:

I use several file-backed thin provisioned iSCSI volumes presented over Comstar.
The initiators are Windows 2003/2008 systems with the MS MPIO initiator.
The Windows systems only claim to be using about 4TB of space, but the
ZFS volume says 7.12TB is used.
Granted, I imagine ZFS allocates the bloc
