Note: Jumper E2 is difficult to find on this drive. It is between the power
connector and a row of 4 resistors. The text "E2" is hard to see because it
is underneath one of the resistors. E2 closed is the preferred setting, but
the drive will still work with E2 open.

If using a different model of drive, make the equivalent jumper settings
according to the above descriptions and your drive’s documentation.
