Is there a way to change the block/cluster size when formatting a disk using unattend.xml & Windows Deployment Services? It keeps defaulting to 1024k, and I need something smaller.

Why do you need something smaller? – Chris S May 19 '10 at 13:24
it was an old image that WDS was having trouble restoring, and we suspected it was partially because the cluster size was different. – Devnull May 20 '10 at 19:45

Appears to be not possible (at least with current implementation). You can bring up the console and do it manually if its really necessary though.
