    Just my 0.02$ . maybe this can help someone.

    some days ago my nvidia raid mirror array shows up as degraded. It was build with two 200gb sata maxtor hard disks and I was booting windows XP from it.
    I was lucky enought to be able to boot into windows (this is what mirroring should do) and I've found that the disk was recognized as a 400gb one. It seems to me the mirror was erroneously seen as a striping unit.
    after that I disconnected one drive at a time anf foind out I can boot from each one. After identifying the most recently used disk I removed both disks from the array (DON'T clear the disk data!). Then I disabled the nvraid in the bios.
    I dosconnected the "old" disk and I verified I can boot from the "new" disk without it being in an array.
    I disconnected the "new" disk and completely erase the "old" one.
    I reconnected the "new" disk and after reenabling the nvraid in the bios, I created a new striping array with only the "new" disk.(DON'T clear the disk data!), leaving the "old" disk unassigned but available to the raid controller.
    After booting into windows I started the nvraid manager and choosed to convert the existing array into a mirror one. everything seems to work fine but the process freezed at 1.56%, no matter how many times I've tried it.
    So I repeted the process up to the erase of the "old" disk, but then I created two striping arrays (one for each disk, DON'T clear the disk data!) and fired up TI9 and cloned the "new" disk to the "old" one. After that I disconnected the "new" disk and I verified I can boot off the "old" disk. Everything worked fine, so I completely erase the "new" disk and assigned as a spare disk to the raid controller.
    after booting into windows and choosed to convert my array to a mirror one (and a wait of about 10 hours) I've got my mirroring array back to life :)

    HTH someone, as I lost 3 days trying to find out why the nvraid controller was hanging during the rebuild. (btw the disks wasn't faulty but it seems like a corrupted metadata stored by the nvraid controller)
