So I will return it and install another one. I am glad I was doing all this as a "testing phase", before I actually deleted the data I was going to put on the RAID. Although I do have more trust in SCSI drives, only one of about 8 failed in my "career", I will go ahead and get another IDE. I bought it and it's "powermax" test failed--quite a bad reputation it should be, however... they're cheap. So I will try again ;) Thanks for everybody helping me! I really appreciate it.
