USB Ports Malfunction

Try a different USB device on each of the USB ports on your computer.
Hopefully, all your USB ports are working correctly.

Try a different USB port on your computer.
Hopefully, the SanDisk will be detected on one of the ports.

Try a USB port on a different computer.
If the SanDisk still is not detected, then spend $10 to buy a new 4GB flash-drive.

Hi,
This error message comes up when you plugged in your USB Flash drive into a lower version of a USB port. Try using another port in your machine, ports that are USB 2.0 compatible and you shouldn't see this error again.
By the way, there are old motherboards which does not have ports for USB 2.0. You might want to check your motherboard user guide and see which ports runs at 2.0. If there is none, I'm afraid that the only way around it is to upgrade into a better motherboard.
Hope this help.

An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files. For example, see: https://services.seagate.com/index.aspx?lng=en-US for a "no data - no charge" guarantee.

Hi,

Even though it is possible that your USB hard driveis corrupt, but

before you finally conclude, try out these few troubleshooting

steps.

First of all, it is possible that the USB port that you are using is a

USB 1.0 port, which has a lower voltage not enough to

power on your Storage drive.

In this case, there are two things you can do,

1. Change the USB port you are using for the storage drive to a

USB 2.0 one (Just keep Checking all the ports one by one in case

you dont know which one it is).

2. If your Storage drive has external power facility, just plug it in

an external power first, before connecting it to the system.

If there are no USB 2.0 Ports on your system at all,

then just go to any electronic store and tell them you want to buy

a USB 2.0 Expansion card.

and if it is a laptop, A USB 2.0 PCMCIA card.

Install it on your system, and connect your external drive through it.

Meanwhile, before you try out the second option, test the drive on

a friend's system, that you are sure has a very good system, with

USB 2.0 port.

If after trying out all these, the USB Drive still doesn't work, then

I'm afraid, the drive might have been bad/spoilt.

Kindly keep me posted about the problem and let me know how it

goes

Hope this helps you out.

Thank you for using Fixya

Goodluck

could be the problem of USB ports try to connect it in back USB ports or another PC

I would like to point out that this must be something the u3uninstall utility did to the usb stick. Mine was working at full speed while I had the U3 stuff on there, and stopped working at full speed in both windows 7 and ubuntu 10.04 after I used the tool. Sorry this isn't a solution, but it's additional info. It's strange it makes it seem like the problem is your OS or drivers and not the usb stick itself, or what the u3uninstall utility did to it.

Hello,
Plug it through different USB ports, even a USB Hub, or on a different computer. Sometimes rebooting solves the problem. I suspect it is a USB problem, especially on laptops with a small number of USB ports.
I have given mine up as dead several times, but it always comes back up gain.
Hope it helps.

Hi there,

Try plugging it in to a different USB port on your computer. Make sure the connecter on the Cruzer is clean and there's no dust inside.

Also, try plugging it in on a different computer.

If none of these work,
I'm afraid it's a hardware problem and there's nothing that can be done about that.

Hope I helped!

1. Download this tool:
http://dl.dropbox.com/u/4040651/HPUSBFW_2.2.3_MASTER.exe

2. Format

(Before removing USB flash drive click on the Safely Remove
Hardware icon and then click on USB flash drive you want to remove)

if you use it on win 95 or win 98 or vista you need specfic drivers for you usb disk
if you get this on win xp please change the usp ports and use another port to insert the disk one of the ports has to recognise.
if the problem persists the usb port controllor on motherboards needs to be checked for faults or uninstalled drivers ,
if nothing works try a pci to usb internal card and dont forget to loaad drivers . this card has 3 to 6 ports for usb
