Disk label type DoS and NTFS? I bet if you could reformat those two drives to ext4 or something more Linux friendly your problem would evaporate. I bet there is a hidden file in the NTFS that the computer is choking on. https://superuser.com/questions/37512/how-to-read-ext4-partitions-on-windows If you need to deal with windows on those drives, look at different options. But I'd see about removing NTFS as a headache. I'm sure someone with more experience in drive management will chime in though. Some people still like ext2 and ext3 as options as well. Got a drive you could format as four, toss some files on, and try and see? If it boots with it plugged in I'd bet that's the problem.
