So... do you have three disks or four? Disk numbering by the system
(based on "c") starts at 0, but quantity (not based on "c") starts
counting at 1. When I was learning math in school and the teacher held
up four fingers and asked how many fingers we saw the answer was four
not three.
Hence your forth disk would be hdd "d" being the forth letter of the
alphabet, and it would not be hd0/hda as there is no hd0, there is hda0
meaning the first partition on the first drive.
