Lexmark X-83 printer

AMD K-6 450 Mhz processor
40 Gb Maxtor Harddrive
184 Mb PC 100 SDRAM
ATI Radeon 7000 video card
Creative SoundBlaster Audio card.
Plextor CDR/RW 40X read speed

I just changed mother boards, put in a new power supply and then found the A: Floppy drive light stays on all the time.

.... Any suggestions on what to do about this ?

all your cable connections. A constant green light after a motherboard change usually means the data cable isn't seated correctly.

I did check my connections very thoroughly and made sure they were secure and in place ...both on the floppy drive and the motherboard. I een changed the direction of the cable...all to no change.

one of the wires in the connector was damaged. Try a new/different floppy cable and see what happens.

floppy drive green light stays on all the time

Most of the time this is caused by plugging the floppy cable backward. Unplug the cable from the drive, flip the cable upside down and reconnect it.

This is a question from the A+ test!!!!!!
The answer is that the cable is reversed at one end.
The cable must be pluged in correctly at BOTH ends.
The red wire on the cable shows the pin 1 end of the connector and must be plugged in correctly on the MB and the drive. John

Cable reversed or bent pin...
by jparkhill / September 22, 2005 10:10 PM PDT

First, check for a bent pin in either end of the cable.

Hook up your floppy cable this way:

How to locate Pin 1.

On the motherboard connection, the red marker on the floppy cable will be facing the same direction as the red marker on the primary and secondary hard drive cables.

On the floppy, the red marker goes next to the power supply cable. You can always flip-flop one cable end to see if that turns off the green light, too.

Try a different cable if this doesn't work.

Pin 1 is not always at the power connector end
by JohnCNR / September 22, 2005 11:56 PM PDT

On Hard Drives Pin 1 is always at the end nearest the power connector BUT on Floppy Disk Drives there has never been a standard imposed.

connect the FDD cable to the MBoard make sure pin 1 is to pin 1 and that you are using the MBoard end of the cable. Then connect the FDD end of the cable to the FDD connection (cable has twist in it) but with Pin 1 away from the power connector.

Hi. You say you just installed a new Motherboard on your machine. Chances are you've plugged the cable from the floppy to the motherboard in backwards. Go through all your safety precautions, then open up, unplug and reinsert. Look carefully at BOTH ends of the cable to be sure. Chances are the green light will go out when you reboot. Rememaber, take ALL standard precautions when touching the MB and other internal static-affected parts.

Good Luck

Floppy light stays on
by andy1512 / September 22, 2005 9:09 PM PDT

There are only 2 reasons for this fault one is the Bus cable is on back to front either at the floppy side which should have pin one facing the power connection or on the board.
However you've checked and made sure this is not the case then the second reason is the drive controller has failed.

The floppy drive controller is usually loaded automatically by the bios or upgraded during the install of windows etc.

Try updating the drive controller from system, it should state standard floppy controller in device manager.

Use your Win XP or which ever op system you have installed and try an upgrade of the driver.

If this does not work then you'll have to install a new floppy drive.

Do without it
by Nebuchadnezzer / September 22, 2005 10:24 PM PDT

If you cannot fix the problem after going through all the previous excellent suggestions, then do without a floppy. Very rarely are they used these days. If you have no real need for a floppy drive, why bother ?

Cable is reversed
by atcontrolr / September 22, 2005 10:29 PM PDT

You have one end of the cable reversed. You need to have pin 1 to pin 1. Take the cable off at the drive and reverse it. Be sure that pin 1 on the board corresponds to the red stripe on the cable.

Don't trust the FDD connector!
by CorkyMuldoon / September 23, 2005 12:13 AM PDT


This happened to me once upon a time.

As many other posters have indicated, the FDD ribbon cable is reversed - and probably at the end connected to the drive.

The documentation I received with a new floppy once said that the FDD adapter was to be connected in reverse! That is - I had to defeat the knockout (or notch) on the FDD end of the ribbon cable. Once I reversed it, the green light only stayed on during boot (looking for a bottable floppy).

This could be the problem but if they just changed the motherboard, then that would most likely be where the cable is reversed. Chances are that the FDD did not go bad between the change in the MB. Hope this helps.

Inverted signal cable.
by Mendieta / September 23, 2005 4:33 PM PDT

Check the signal cable, it's much probably inverted, pin 1 conected to pin 40, the signal cable has a red stripe that must be conected to pin 1 on both, floppy unit & controller, most floppies has pin 1 near to the energy conector, but not all floppies, there are some exceptions, to be shure look at your floppy unit conector, there must be a number "1" printed near pin 1 or a small triangle, that's pin 1, on the mother board manual must be indicated which pin is Number one & probably on the motherboard too.

Hope this helps you.

I forgot to say...
by Mendieta / September 23, 2005 5:01 PM PDT
In reply to: Inverted signal cable.

Some floppies have a plastic box around the 40 pins that prevents reversed cable on the floppy side (just like the motherboard controller has), this plastic guide box also prevents pins to be left out from the cable conector & to be bended for the same reason, but some floppies don't have this platic box guide, if yours doesn't have that plastic guide, disconect the cable from the floppy & check out if some pins are bended out, if so, carefully realign them and conect the cable again.

Try also another cable, maybe your motherboard came with new drive cables and if you use the new ones, can be that the new cable is defective.

I don't think that your floppy can be defective if it was working before the motherboard change.

I had this problem
by The Dud / September 24, 2005 2:54 AM PDT

When ever I put a floppy drive in a computer I always get the green light that stays on, for me it was a simple fix. On the back of the floppy drive the cable could be upside down, because most arn't notched like on CD/Hard Drives. If you flip it and it still is green flip it on the mother bord. Try some diferent combonations.

floppy dks light stays on.
by liondad0 / September 24, 2005 5:02 AM PDT

One. Replace drive,
Two Replace drive lead,
Three look at pins in mobo socket and the solder joints and the component in and around the socket,
i a feeling your find a capacitor has got to the end
of its life and is leaking,
if it not one or two,
its three,
Four replace mobo,
trying to replace a capacitor on a four layer mobo,
is not fun.

Figure this out
by Drake1132 / July 7, 2006 8:10 AM PDT

Got a new comp
floppy light stayed on
checked all cables - no change
checked cables in another computer - all fine
checked floppy drive in other comp - light stays on

this would suggest it was the floppy right?


used second floppy from other comp(which was working fine) in new comp
Light stayed on...... argggggghhh
put second floppy from other comp back into other comp

Are my floppys dead? Has the m/b or psu in new comp done something to them?

Please help!!!

FDD light staying on
by riktek / February 3, 2010 7:03 AM PST

Had this problem recently, and followed all recommended procedures without success, including flashing bios. When the o/s was up (WinxP), the drive was seen, but kept coming up with the message "Please insert floppy disk in drive A". As the problem occurred during bootup then persisted, as a final resort,I reseated the memory. Problem solved. Hope this helps.

In file explorer click on This PC  then double click Floppy Disk Drive (A) which will respond with Insert disk click Cancel and all is kosher.
