Now that many workstations are coming with RAID-1 mirrored hard drives, taking them offline to get rid of rootkits have gotten more complicated. I have a RAID-1 computer that has a particularly awful rootkit. I'm going to rebuild it, but if it was just a single hard drive, I'd take it out, connect it to my own computer and run scans on it that way. What's the comparable practice if you're dealing with RAIDed disks. How do you interact with them without booting into their OSes?
