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.

I no longer have the transfer disc but have new laptop I do not have the nikon transfer software that came with the camera. I want to take the pics I have taken off of my camera transfer over to laptop


Hi,
Connect the camera to your computer with the USB cable. Wait for the operating system to detect the camera.
Double click on Computer or My Computer. In the list of drives you should see "Removable Devices". Double click on that/them and copy the files to the computer.

If the computer does not see the card (removable device) then check that it's inserted properly in the camera and that the write protect switch is in the off position.

Failing that if you purchase a card reader you can take the camera card out and put it in the card reader and connect it directly to a USB port on the computer to transfer your flies.


Regards.

Computer won't recognize my nikon coolpix 4600


You need to give some additional information. What OS are you using? USB, with all newer OS's is native and you shouldn't have to have any special drivers or software to get the camera detected by the computer. Simply plug it in and go to "My Computer" and it should be seen. If this is not the case, start with the physical connections first. Check the USB cable between the two. if a 2nd cable does the same thing, check a different device with the same cable and connection port on the computer. If the port works, and it recognizes another device, you have to look at the camera. If it doesn't recognize the 2nd device, look at the port on the computer. If ANOTHER port doesn't work, go into the Hardware device manager and ensure that USB ports have not been disabled. If it's the camera, chances are the port has died. If this is the case and you don't want to trade the camera in, try getting a $30 card reader and place the data card into the reader to ensure that the card isn't the issue. The reader will ensure that you can transfer the images and will also save some wear and tear on your camera.
