It is often necessary to install a second floppy or optical disk drive in your computer. So that there is no conflict between two drives connected to the same loop, certain rules should be followed during the revision of the machine.
Instructions
Step 1
Shut down the operating system. Power off the computer.
Step 2
Before installing a second optical drive, make sure ribbon cables are connected to both IDE connectors on the motherboard. If this is not the case, connect the second ribbon in such a way that the conductor with the stripe (usually red) is connected to the pin of the connector marked with number 1.
Step 3
To prepare the system case for the installation of the drive, remove the plastic cover of one of the 5, 25-inch bays from the front panel. If there is a second, metal plug behind it, break it off.
Step 4
Slide the drive into the bay, then secure it with four screws on each side.
Step 5
Correctly redistribute the drives between the loops. One of them must have only optical drives, the other must have only hard drives. Connect the ribbon cables to all drives in such a way that the stripe conductor faces the drive's power connector.
Step 6
Previously, the machine had three hard drives and one optical drive, but after installing the second optical drive, one of the hard drives will have to be disconnected. In the future, it can be connected via a RAID controller or a USB-IDE adapter.
Step 7
Now you need to set the jumpers on the drives correctly. Jumper positions for "master", "slave" and "cable select" modes are indicated on the drive cases. To change the mode on a hard disk, you usually have to rearrange several jumpers, on an optical drive - only one. On each of the loops, either switch one of the drives to the "master" mode, and the other to "slave", or switch both drives to the "cable select ".
Step 8
Be sure to connect the power connector to the newly added drive.
Step 9
Connecting SATA drives has two differences. First, there is no need to select the "master" and "slave" modes. Secondly, the loops of this standard are of two types: with seven and fifteen contacts. You need to connect the power connector to the drive only in the first case. If you apply power through a separate connector to a drive connected in the second way, it can be damaged.
Step 10
The floppy drive fits into a 3, 5, or 5, 25 bay, depending on which floppy it is designed for. A special 34-pin ribbon cable is used to connect it. On the newly connected drive, it is necessary to select with a jumper, if any, the same mode as on the existing one. If the existing drive is connected before twisting on the cable, the second is connected after it, and vice versa. The ribbon cable, which does not have a connector before twisting, is designed for the connection of only one drive - it must be replaced with another. Note that 5, 25-inch drives use specially shaped connectors that are not found on all cables. In this case, the cable must also be replaced. The red wire on the ribbon cable should face the power connector of the drive.
Step 11
5, 25-inch drives use large power connectors, such as those found on hard drives and optical drives. For 3.5-inch drives, special reduced-size power connectors are used. It is important to connect the latter correctly, paying attention to the key, otherwise the drive will receive a voltage of 12 volts instead of 5, and it will be instantly disabled.
