In-Depth Information
The master jumper indicates that the drive is a master or a slave. Some drives also require
a slave present jumper, which is used only in a dual-drive setup and then installed only
on the master drive—which is somewhat confusing. This jumper tells the master that a
slave drive is attached. With many PATA drives, the master jumper is optional and can be
left off. Installing this jumper doesn't hurt in these cases and can eliminate confusion; I
recommend that you install the jumpers listed here.
Note
Note that some drives have these jumpers on the drive circuit board on the bottom of the
drive, and as such they might not be visible on the rear.
