Hello! I managed to install Windows 7 beside my Os X snow leopard and for some reason my external hard drive (Lacie 1Tb) is in "read only"-mode in windows. In OS X it works like a charm. I did try the HD on my other PC (also windows 7) and it worked just fine. So I figured the problem must be caused by boot camp/ OS X...?? I tried to solve the problems in Windows using the error code that the HD writing effort provided: 0x8007005. No succes. I'm very grateful on any ideas on this matter. Cheers!
