Yes, that is correct.  And if one is missing (like you only have
ide1/master and ide2/master, they still are hda and hdc.  The system
doesn't re-letter them to be hda/hdb or anything.  On the other hand,
scsi disk drives do this behavior.  /dev/sda = first scsi hd, sdb =
second, etc.  That got annoying when I removed one of my scsi disks and
everything went out of whack.

One question I had once, how many partitions can a drive (IDE or SCSI)
have?  I know IDE hds can only have 4 primary partitions, but are the
logical partitions in an extended limited?  SCSI I think I read
somewhere can have more primaries, but anyone know how many?
