I hate to bring up an old post, especially as a new poster, but I ran into the same problem. The deal is, even though the drives do show up in the windows environment with the ex2 program, they show up as separate drives. This is probably because they are in a software raid on by the Linux OS. in XP, the separate drives show up, but windows does not see them as even being formatted. So its not such a cool thing that we see both drives in Windows.
Is there some way to have Linux continue to do its thing with the software raid, so that XP sees the RAID drive as a single drive rather than two unformatted drives, or is this only a pipe dream?
Is it possible perhaps to have both operating systems software RAIDing (by the way, is there a verb for this?) the drives with the ext2 format and to keep the data intact between OS's?
