I had this same problem. What I figure is that the Fujitsu drives are junk! But I found a work-around. I put a small 5GB IBM drive in mine as the slave drive, and everything works. Take it out, and I have the exact same problems you have. I really think it is the drives. I figure the fact that you can't auto update hijack doesn't fall under the warranty... besides the Fujitsu I have is my 3rd one. If you can get a spare drive to check it out, do it.
