I have a power vault 600 which was holding all my backup data for a couple of servers. When i show up today one of the hard drive sliders is flashing from green to amber and will not boot seems like it doesnt recognize the drive. I've never really worked with this server and am not sure what configuration they had the hard drives. Seems like someone went in there an removed the drive so i put it back in and made sure its secured in its slot. No luck Any ideas??
