Note: If you are using an IDE hard drive 1 Gigabyte in size or smaller, refer to the following FAQ: http://www.startech.com/faq/hard_drive_accessories_minimum_ide_hard_drive_size
If you are unable to detect your IDE (PATA) drive using a StarTech.com product, you may need to change the jumper settings on your drive. The jumpers switch the drive between Master, Slave, and Cable Select for most drives. A jumper is a small plastic piece that slides on top of two pins to electrically short them together.
When it does not mention what IDE drive configuration is required or if there is only one drive in the setup, the drive should be configured as Master. If Master is not working, try using the drive in Cable Select.
There is no standard position for the jumpers on IDE drives. On some drives, the jumper diagram is on the label that is on the top of the drive. On other drives, there are markings on the circuit board for CS, MA, and SL, which means a jumper shorts the pins vertically in that position. For more information, refer to the documentation provided by the manufacturer.
