Buying tips and help

If you have not already purchased a floppy drive see the floppy buying tips section help before continuing.

Note: This page is written for computers that have had an internal floppy disk drive. Newer computers and operating systems no longer support internal floppy disk drives.

Tip: If you still need access to a floppy disk drive we suggest purchasing a USB floppy disk drive that is compatible with your version of Windows or Mac.

How to determine the floppy drive type

Before getting started

  1. Write down important information from the top or bottom of the floppy disk drive such as the Model Number, Serial Number, and specifications.
  2. Ensure you are familiar with ESD and its potential dangers.
  3. When physically installing the standard floppy disk drive, ensure the computer is powered down and unplugged.

Remove existing floppy drive

If you are installing a floppy disk drive to replace a faulty one, begin by disconnecting all cables from the current floppy drive and then remove it from the system. Most systems will require that a screw or set of screws be removed before the drive can be extracted. Other drives are attached to a removable bracket that can be pulled out by pressing and holding two tabs.

Note: If you do not see screws, some systems may hold the drive with a screw on the front of the case.


Open the computer case and connect the floppy drive to the computer using screws or a bracket.

Connect Cables

Once the new floppy drive has been connected into the computer, connect the floppy interface cable (small gray flat cable) to the back of the floppy drive. The floppy cable has a side with a blue or red side indicating pin number 1. This side of the cable will point to the power connection. If your computer floppy cable has three connections or a twist in the cable, ensure that the cable is connected properly by referring to the picture below.

Floppy cable

Today, most computers and computer floppy disk drives have cables that only have two connections: one for the motherboard and the other for the floppy disk drive A. If your cable only has two connections, the above picture does not apply.

Once the floppy interface cable has been connected to the computer, connect the floppy power cable to the back of the floppy disk drive. This cable is a small power cable when compared to the other power cables coming from the power supply.

Setup CMOS

Once the floppy drive has been connected to the computer, place the case back onto the computer and connect the keyboard, monitor, and power to the computer (we recommend that you do not connect all the cables yet, if problems are experienced you may have to disconnect all the cables again).

Once connected, turn on the computer and enter CMOS setup. Verify that the floppy drive is properly setup within BIOS, most likely as a 1.44 MB 3.25" Floppy A.


If additional issues are encountered during or after the installation of the floppy disk drive, refer to our floppy disk drive page for additional help and information.
