I have this ASUS M2NBP-VM motherboard http://tinyurl.com/3xby3h running CentOS 4.4 as a web/email server. It has a 500Gb SATA2 drive with about 32Gb in use. The motherboard supports hardware raid. Is there a way to switch to RAID1 without reinstalling or loosing any data? Also, if I am running raid how do I know if there is a failure on one of the drives anyway? Is hardware RAID1 a good idea?
