Default External USB Hard Drive no longer works

I have been using an external drive for backup - but as of today, I
cannot 'see' it in 'Computer.' It is turning, but not showing up on my
monitor. Is there any way I can check to see what the problem is? The
cables seem fine.

Have you tried another USB port or another USB cable?

Have you opened it up to see if the cables are still seated properly?
It is also possible that the power supply has failed and that there
might be enough juice to turn it, but not run the electronics (a long
shot, but possible).

External drives DO go bad also and this one may have just done that.

Haven't tried that yet - but will.

What would happen if the hard drive was 'accidentally' shut off (during
or not during a backup)?

Most likely, some corrupted data.

Method 1

*For Microsoft Windows Vista (and windows 7)
Click Start, and type device manager in the Start Search box.
Click Device Manager in the Programs list.
If you are prompted for an administrator password or confirmation, type your
password or click Continue.
In the Device Manager dialog box, expand Universal Serial Bus controllers.
Right-click USB Root Hub and then click Properties.
In the USB Root Hub Properties dialog box, click the Power Management tab.
Remove the check from the Allow the computer to turn off this device to save
power check box. Repeat steps 1 through 4 for each USB Root Hub listed in
the Device Manager.


Under Power settings, check the 'USB settings' - 'USB selective suspend
settings' and make sure it is disabled.

Check Thumbnail, highlighted: Open Device manager, Double click on Universal
Serial Bus controller at the bottom, Double Click USB Root Hub, Click Power
Management on top right, Uncheck Allow Power...

Method 2

*You can disable the USB Selective Suspend feature as a workaround by
editing the registry. The USB device may become unresponsive because of a
race condition in the Selective Suspend feature. The Selective Suspend
feature suspends the USB device to efficiently maintain battery power by
enabling the computer to turn off the USB device. However, sometimes this
feature may not correctly wake up the USB device. Therefore, the USB device
is unresponsive when you try to use it.
You might want to disable this feature for server products where power
management is not important or required.
*To disable the Selective Suspend feature, follow these steps:
Click Start and then click Run.
Note If you are running Windows Vista, click Start, and then use the Start
Search box.
Type regedit, and then click OK. Registry Editor opens.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\USB
If the DisableSelectiveSuspend registry entry is present, double-click it.
If it is not present, create the entry. To create the entry, follow these
steps:
On the Edit menu, point to New, and then click DWORD.
Type DisableSelectiveSuspend, and then press ENTER.
On the Edit menu, click Modify.
In the Value data field, type 1 to disable the Selective Suspend feature,
and then click OK.
