Mounting the Floppy Drive

Now you should mount the drives into the case. The floppy drive should go into one of the smaller (3 1/2") bays.



Make sure that it is flush with the front of the case, and then put the screws in. While it is always better to mount the drives with four screws, only two are really needed. If you are only going to use two screws, make sure that they go in opposite corners (left front/right rear or right front/left rear).



Next, you have to connect the floppy cable. The floppy cable will be the one that has a weird twist in it.



One of the wires should have red dots on it (on the left, in the above picture). The red dots indicate with side of the cable should line up with "pin 1" on the motherboard and on the drive.

Locate pin 1 on the floppy controller on the motherboard. If you can't figure out which one is the floppy controller, just compare the size of the floppy cable connector with the different sockets on the motherboard - the floppy cable will only fit into one of those sockets. In the below pictures, the floppy controller is the bottom one. Note that the IDE controllers have sockets that are longer than the floppy controller's. You may have to consult the manual for your motherboard if you can't figure out which one pin 1 is. If you are looking at the socket, and the notch in the socket is on the bottom, then pin 1 will be on the left side. The bottom picture show a close up of the same connectors after cables have been hooked up. Note that on the lower left side of each IDE socket is a printed "1" indicating which pin is pin1 (it's kind of hard to see, but they're circled in green). Also note that the red side of the cables correspond with the pin 1's.





Sometimes, the motherboard will actually have "Pin 1" labelled on it.



Then connect the floppy cable to the drive itself. The end that you connect to the drive should be the one that has the twist in it. When you power up the computer, if the light on the front of the floppy drive comes on and stays on, then you have connected this cable incorrectly. The light on the front of the floppy drive should come on briefly and then go off. If the light does not come on at all, then you either have a defective drive, or you have forgotten to hook up one of the cables.



Finally, connect the power cable to the floppy drive. The floppy power connector will be smaller than the rest of the power connectors. Make sure that the power cable lines up with the pins on the back of the floppy drive. This typically involves a lot of force to connect. And they are usually very difficult to disconnect. So, before connecting it, make sure that it's where it's supposed to be. Note that in the below pictures, pin 1 on the drive itself is denoted by a triangle that has been stamped into the drive, just below and on the left side of the floppy connector.

I seen your blog using google and I must say, this is probably one of the best well prepared articles I have come across in a long time. I have bookmarked your site for more posts.
