In 2.4 there used to be a megaide driver for certain ata raid controllers. In 2.6 I can't access more than my /dev/hda , I can see my other 4, I can create filesystems on them, but I can't mount them Anyone knows how to use these on a 2.6 kernel (Centos 4.2) greetings Kris 00:02.0 RAID bus controller: Silicon Image, Inc.
