Jumper settings on the IDE device set the device to master or slave (see the documentation
that comes with the device). Drive letters will be assigned to physical drives as follows.

When drives have multiple partitions on them, partitions beyond the primary partition will
be assigned in ascending order, based on available drive letters and other installed drives.
Partitions are assigned to primary partitions first, and then to secondary partitions. This
means that when there are multiple drives with multiple partitions, the logical drive
numbering scheme may result in discontinuous logical partitions on the same physical drive.
For instance, if "Drive 1" is the master drive on the primary connector has two partitions,
"Drive 2" is the slave drive on the primary connector with three partitions, and "Drive 3" is
the master drive on the secondary connector with two partitions, the drive letters will be
assigned as follows.
