Color LaserWriter 12/600PS: Installing Internal Hard Drive

I'm trying to install an internal 40 MB hard drive into my Color LaserWriter 12/600 PS. It is not recognizing the hard drive. When I power up the printer, the status panel indicates a hard drive error; the following LEDs are on: [Paper Out/Paper Jam/Magenta toner/Maintenance Light #2].

When installing the hard drive, I noticed that the connector on the hard drive is larger than the ribbon cable connector. On which side of the hard drive connector should I align the ribbon cable?
It's likely that the ribbon cable is not properly connected to the hard drive.

Align the ribbon cable on the left side of the hard drives connector. After the ribbon cable is connected, there should be four rows of pins exposed on the right side of the hard drive connector.
