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 dont 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 cheack 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 "Safly 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

It would be very decent of you to consider the quality of our experts answers and judge them accordingly as you pass through FixYa.

Thank you

1. 1 Insert your memory card into your computer's reader if you have one. If not, you can purchase a multi-format USB Memory Card reader from Amazon.com or Buy.com
   
2. 2 Open up 'My Computer'. You should see it under the list of available drives.
   
3. 3 Check its contents first to make sure that you have the right drive.
   
4. 4 In 'My Computer', right-click on the drive and choose 'Format'.
   
5. 5 Leave all the options as they are and click on 'Start'. This is a non-reversible process so make sure this is what you truly wanted to do in the first place.
   
6. 6 Once the process is completed, take the memory card out and insert it into your Digital Camera or any other device. Try to browse to it to make sure it works fine now.
