External floppy drive causing system failure.

I have an Acer Aspire laptop and a Dell D800 laptop.

I have a Packard Bell and Dell usb external floppy disk drive.

The 2 floppy drives cause a serious system failure on both computers.

My partner also has a Dell laptop.

The 2 floppy drives install and work perfectly on it.

Why won't they work on my laptops especially the Dell?
Is there anything I can do?.

Any help would be appreciated. Thanks.

 

A better definition of the differences between the systems that work and the ones that don't would be helpful. Things like operating systems, computer model numbers, USB 1.0 or 2.0 on which computers, etc.

 

Hi Schnerdly

The Acer is an Aspire 3660 series.
The Dell is a Latitude D800.

Both work on windows Xp with usb 2.0 I believe.

My partners Dell is a Latitude D810, which also works on windows Xp and usb 2.0 ports.:wave

 

Are these drives your using bus powered off the USB port or do they have a separate supply?
It's possible that the power from those USB ports is bottoming out as the motor spins up and the
D810 machine has a slightly stiffer supply that copes better with the surge current, the way to
prove or disprove this would be to plug the drive into a powered USB hub.
When you say 'serious system failure' do you mean it goes off or blue screens with any error warnings?

 

Hello people I think things have just got worse!!

The laptop doesn't have any other usb hardware connected.
The floppy drives were connected direct to laptop not a powered supply.

When I connect them the screen goes black with a lot of writing and shuts down in a second (no chance to read anything) then reboots stating the computer has recovered from a serious system error.

Today I have switched the computer on and all I am getting is a black screen, windows is not loading, if it is, it is hiding.:confused

 

If you have the XP disk you could try doing a repair install. If your lucky the floppy drive might also
start working.

 

Have now got windows back from black screen by pressing F8. Guesswork.:confused

Don't have windows disks to be able to perform repair.

 

Update.

When computer shuts down I have following Info:-
A problem has been detected and windows has shut down to prevent damage to your computer.

Stop 0x0000007E (0xC0000005, 0xF7BE7A05, 0xF7C8A548, 0xF7C8A548)

Hello
I have the same usbstor as the dell 810.
I have run sfc scannow and it keeps asking me to insert xp professional sp3 disk but the computer didn't come with any disks and it is xp home installed not xp pro.

 

I uninstalled all software I put into the Dell laptop so it is back to how it was when I had it.

Reinstalled the floppy drive, but then I had a message saying ' A problem occurred during installation, your hardware may not work properly'.

I went into device manager and there was a yellow circle with exclamation mark next to the floppy drive.

I uninstalled then reinstalled again and received the message 'windows cannot load the device driver for this hardware. Driver may be corrupt or missing (code 39). :cry
