I've installed Windows Vista Ultimate x64 with almost no problems, except for\none.\n\nI dual boot with another operating system, and created a RAID array with a\ndifferent filesystem (i.e. not NTFS.) It uses the GPT partitioning scheme.\n\nVista does recognize the big RAID drive, but it thinks it is a RAW\npartition. There is another filesystem on it, and I found out selecting it\nasks me if I want to format the partition. I obviously don't, as there is\ndata on it.\n\nIs there a way to just hide this device so it doesn't get a drive letter? Or\nbetter yet, have it detect properly so the ext2/3 driver can access it? The\next2/3 driver documentation will support GPT if Vista can access the drive\ncorrectly, and currently it isn't able to do so.
