If the computer does not recognize the external drive, plug it into another computer to ensure the drive is not corrupted. If the drive is good, a few simple steps should help re-enable the drive for use.
Switch the power button to "off." Disconnect the power cord from any extension cords or power strip, then re-seat the power cord into the hard drive. Connect the cord directly into an outlet and power up the drive. If the drive is powered and still not working, check the data cable. Power down the hard drive and disconnect the data cable from the computer. Wait 30 seconds to one minute. Reconnect the data cable and power up the drive. If the drive is not detected, power down the hard drive and connect the cable to a different port. Power up the drive. If the drive is detected but not working, check for a missing driver. Click on the "Start" button, right-click "Computer" and select "Manage." Enter your administrator password if requested. Select "Device Manager" and double-click "Disk Drives." Right-click the yellow exclamation point and install the missing driver. Close the Device Manager. If the drive is detected but not working check to ensure it has an assigned drive letter. Disconnect all devices connected by USB cables from the computer. Reconnect the drive's data and USB power cables directly into the computer. Click on the "Start" button, right-click "Computer" and select "Manage." Enter your administrator password if requested. Click on "Disk Management," right-click the external hard drive, click "change drive letter and path," and click "Add." Assign a drive letter. Avoid using A, B or C (C is usually assigned to the computer's internal hard drive). Click "OK" close the window. If the drive is detected but not working, check whether the drive is in sleep mode. Disconnect all devices connected by USB cables from the computer. Reconnect the drive's data and USB power cables directly into the computer. Click the "Start" button, right-click "Computer" and select "Manage." Enter your administrator password if requested. Select "Device Manager" and double-click "Universal Serial Bus Controllers." Double-click the first instance of "USB Root Hub" or "Root Hub." Check for the hard drive. If the drive is not visible, move to the next instance of "USB Root Hub." Continue checking each instance until the hard drive is located. Once located, click the "Power Management" tab and uncheck the "Allow computer to turn off this device to save power" box, click "OK," then close the Device Manager. Power the computer down, wait 30 seconds to one minute, and power the computer back up to ensure the drive is detected. Hope this helps.

check under the system profiler which can be found in the applications folder and then in the utilities folder. See if under usb whether the drive is showing under there. If it is, open up disk utility and use the verify disk to see if there is a problem with the drive, if there is use the repair disk to repair it.

Other things to check try a different usb port on the macbook or a different usb cable.

Hope this helps

I devised these simple steps that tend to remedy quite a few issues with most portable / external hard drives (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems 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.
If you checked and fixed anything there and still have issues carry on reading.
Go to your control panel and then administrative tools, select Computer Management.
Now select Disk Management and expand the window.
Your drive should be listed here, if not then you need to check your computer hardware has not got any issues before proceeding.
If your drive is listed and says healthy then right click on it an select Properties, click Tools and then Error Checking, Check now, tick the two boxes and then Start.
This will attempt to fix most minor / common errors on the drive. It may also ask you to restart which is fine. Allow it to finish its work or you could corrupt the drive. If all went well you should be able to use it normally again.
If you drive was listed but did NOT say healthy then right click and select Format. Choose NTFS as the file system and do not tick any boxes you do NOT want quick format. Again start and let it do its thing. When it is done restart your computer and you should be good to go.
If you still have problems with the drive you might want to look at other areas.

WinXP SP2 blocks the use of the drive because it thinks it draws too much power. But there is a simple procedure to override this (from WD site):

"Problem:
Under Windows XP, an error message of "Power Surge on Hub Port" or "USB device has exceeded the power limits of it's hub port" is displayed when connecting a USB device to a USB port on a computer or Hub.

Cause:
Under some computers, USB devices are only allowed to draw a maximum of 500 milliamps (mA) per connection from the USB port on the computer system or from a USB hub. Under the Windows XP Operating System, with the release of Service Pack 2, if a device attempts to draw more than this (500 milliamps), a USB port balloon message is displayed to indicate this over current condition. When connecting a USB device that draws power from the USB bus, a very brief over current condition is sometimes detected by the OS, and the warning message is displayed.

Resolution:
This message has no affect on the functionality of the USB port. The USB hard drive should still function correctly on the USB port regardless of the error message. To prevent the USB Power Surge Alert message from displaying, please complete the following steps:
Click on Start.

Click on Control Panel.

Double-click on the System Icon.

Click on the Hardware Tab.

Click on the Device Manager button.

Click on the + next to Universal Serial Bus Controllers to expand the selection.

Right-click and select Properties on any listing that displays USB UNIVERSAL HOST CONTROLLER.

Click on the Advanced Tab.

Check the box that says: Don't tell me about USB errors."

This works fine, and the drive works fine afterwards. I suspect it actually draws less power than they say. Maybe it has a brief power draw spike on startup, but it's running power seems less. In any case, it works fine without the Y cable. I do think it is tacky that WD doesn't give the cable for free, since my $7 Sabrent 2.5" Hard drive enclosure came with a y cable.

But most likely the drive will work fine for you. It is a lovely quiet drive, and takes up no space at all.
