You misunderstood why I mentioned the Ext3 driver for Windows. I wasn't suggesting you convert your Windows partitions to ext3. I was suggesting you educate Windows about your existing Linux partitions.
This is an evolved thing. It started out as 1 300g drive then 2, thena third and I did some jugling to go raid 5 this involved HDs into a previous place I worked and filling they're file server with 500+G of data and then back off. Now its a single drive over 1 TB NTFS formatted and its something of a nightmare. There is no sane way to back it up in order to go from NTFS to Ext3. I trust accessing the drive using a questionable kernel module over doing some kind of ntfs to ext3 conversion.. if its even possible.
