USB drives not recognised.

When I attach external USB stick drives to the computer, the message appears that drive is not formatted. If I select to format it the message that the drive is not recognised appears. The drive icon appears faded and flashing on and off.
I have tried different ports and cables and attached the drives directly to the computer. The computer was also restarted.

OS is win 7
Computer is Advent.

Any further advise would be appreciated.

Hi

I followed the steps in the links above, but the problem remains.
I would just like to mention that the issue is with these kind of small USB storage pen and key devices (4 in all). I have several other USB external "hard drives" and they connect and disconnect without any issues.

I will give the exact windows messages I am getting:

After the pen usb drive is connected there is the dump-duh sound, and the new drive icon appears but as faded and flashing on and off. A message appears in the taskbar that the driver has successfully installed and is ready to use.
But if I click on the faded flashing icon, the messages are as follows:

1. You need to format the disk in drive G: before you can use it. Do you want to format it. Format & Cancel.
2. There is no disk in drive G. Insert a disk, and then try again.
3. Check to see that the disk and drive are connected properly, make sure that the disk is not read only, and then try again.

Any further information would be appreciated.

Please try this:

UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.

Firstly to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!

So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute or even longer and then plug it back in.

regards,
