My Dynamic Disk is offline

I got a test version of Longhorn and installed it. It was boring. The default font cannot display Chinese characters. I changed the Chinese font and the English character became ugly,. the Chinese version of net2003 is not available yet, so I switched back to Windows2003. Unexpectedly, after I got back to 2003, my two dynamic disks changed to "offline", which was hard to be re-activated and did not reflect the problem, the thought could be Longhorn's hands and feet on the Dynamic Disk, resulting in 2003 being unable to be re-activated, so I hurried back to Longhorn. Fortunately, my files are still there and there is no way, there are too many things in the two hard disks, but they are not ready yet. Please wait and buy another GB hard disk!
