Uh-oh -- it looks like the nasty Windows Home Server bug that corrupts data affects quite a few more apps than Microsoft initially let on.
The company's just updated the WHS support note to include reports of data corruption when using iTunes, the Zune software, WinAmp, WMP 11, Photoshop, and a host of other applications -- and the problem's expanded in scope as well, now affecting files saved to the server in addition to files edited on the server.
That basically makes WHS useless as of right now -- if you can't trust your data on it, there's no point -- so let's hope there's a fix on the way.
