Hi vvulture,
There is a known bug within Windows Home Server in that it corrupts files...
Microsoft: When certain programs are used to edit or transfer files that are stored on a Windows Home Server-based computer that has more than one hard drive, the files may become corrupted
I received a demo version of the software, but once I heard this I decided not to install.
Having said that, the concept of WHS is a good one, and once this bug is fixed I'll be investigating.
