For IDE hard drives, it’s important to properly set the jumpers. If not properly done, your computer may not boot or the hard drive won’t be detected.

If more than one device is on an IDE port, one device must be set to primary and the other set to secondary or cable select.

Many early hard drive jumper settings are on our hard drive specifications page.
