D5-300 all lights red and 4 peeps in a row NOT DETECTED

[acodemonkey99]

I have the d5-300. I use to have 5 drives in there but they moved to another project when I put the new drives in they all went red and the d5-300 is beeping 4 times in a row stopping and repeating. It also is not being recognized with in raid master on two separate computers with or with out the drives in it. Please help. The other drives have been wiped and are in another project. I need to get this original enclosure back up and running with a new raid 5 array.
