Try using a different USB port. Try pressing F5 to refresh the components list from within Explore. You can also hard-wire it in if your computer is a Desktop model.

I had a similar issue with windows 2008 and windows 7. the drive lost all its info and had to be reinitialized under both of those O.S.'s..
You can try that as long as it doesn't have any data you need.. Once you do that the drive will work and you can start using it. The file system under vista and above is slightly different than xp.

is it set up by usb or serial port. if usb try unpluggung it and restarting computer then plug it in. you might want to go to manufacturs website and see if they are updates for the drivers

Hi,
This generally means you have a hardware failure in the drive or enclosure. The simplest way to test which is to have a hardware tech move the drive into a new enclosure and see if it works.
This will void your warranty if you do it, so, if the drive is under warranty and there are no files you consider valuable on the drive, call the manufacturer for warranty support.
If you value the data more than the drive is worth then take it to your local hardware vendor and ask them to test the hard drive in a new enclosure. Good odds it will work this way but if not you may need the help of a data recovery specialist.
In North America I use Armor-IT, if you are in a different region and the new enclosure fails to garner results, comment back with your region(Country, State, City) and I will supply you with the closest reputable facility.

OK, 2 things to check. First and foremost, when you plug it into the PC does it make that nifty noise to let you know it sees a new piece of hardware?
Second, if it does, you probably need to initialize the disk. Hit the windows button, right click on computer, and select manage. Under the storage category highlight Disk management. If you see the drive there, you can right click and select initialize, or format. From there the system should see the drive.

One or more of the hints below will probably sort out most USB problems with most USB portable / external hard drives and OTHER devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
6. For FLASH DRIVES you should ensure that the device is set for "quick removal" using the drive control panel properties or use the USB "Safely Remove Hardware" option. If you don’t do this there is a very strong chance that any files you transfer may not be there when you plug into another computer.
7. It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
You should also do this to check the drives connections are not bad inside the enclosure.
8. If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.
9. If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further
10. Ensure that you have set removable drives for "quick removal" or that you use the "Safely Remove Hardware" option often shown on the lower toolbar. It is possible that files my not be fully written to external devices before they are removed. This corrupts the file itself and even on occasion the drive.
SPECIAL NOTES
USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.
USB hard drives should be treated with extreme care.
This is a real hard drive ! And knocks and bumps can quite literally kill them.
Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.
Known as "The Click of Death"
Hope this gives you the information you need
