Moving to the Laptops forum
When you say 'recognized' do you mean to do a certain task? Because if you check dmesg the drive should be properly recognized during startup, however for the dynamic changing of the drives you'll probably need to make an itricate system of /etc/fstab entries to correspond, none of which should be using the option 'auto'.
Just a guess though, figure I'd contribute since I had already responded to let you know I was moving your thread
