I can test the code once it's done. I just moved my / to the RAID1 provided by IT8212. The controller has a great feature that allows converting a drive between RAID1/standalone without data loss (haven't seen anything like this yet).

I sold it including the controller a couple of years ago (it was still working) so no testing fun for me. > Alan -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
