I did all of that before posting this thread, and yes my computer itself is ok.

Western Digital

If you can't reformat it, nip out and get a new one and back up ASAP.

since, I my computer can't see it at the moment,  I don't know how I would reformat it.

yeah, I'll have to see if I can get it apart.

First you should really make sure it's the harddrive itself that's not working.

Does the harddrive have any light, and if so, does it blink when you connect the drive?

Does the harddrive make any sounds, if so, does it sound as it normally does or do you hear an unfamiliar "clicking"? (Clicking usually means the drive is dying)

Have you tried going into BIOS at startup and make sure that the USB (or whatever port it's connected to) is activated? Don't know why it would deactivate but always good to check.

Also, have you tried all ports in the computer, both front and back if you have any?

Have you tried going into the Windows device manager and checked if the drive is listed there?

If the drive is listed in "disk drives", remove it from there and reconnect it and Windows might find it again.

Also check disk management.

the light comes on when I connect the drive.

yeah, I think I do hear a clicking.

I don't think it is.   I was able to plug my Ipod into it and it connected to my computer just fine.

I haven't tried all ports, but I have tried multiple ports, to no avail.

I see something in there, I am not sure what it is.   I am uncertain whether its the back up drive or something else.   I am not sure I want to remove it and risk the situation getting worse.

edit: I think it is the internal hard drive of my computer.

I don't see the back drive in there.

Ok, from what you're saying, it does seem like the drive is failing, but the cable could be bad. Do you have any other USB cable that you could try connecting it with?

Now that I think of it, I've heard of some WD external drives that had some faulty power cables. No idea if it can be related to this but you might wanna unplug it and replug it and see if anything happens. The drive sure wouldn't work without power.

I am not sure,  I have anything to connect it with.   I have cords with a USB end to it, but not with the end that would go into the back up drive.

edit: I just found away to test this.  Its turns out that my printer also uses a USB connection that the  part that plugs into the printer matches the part on the other cord that plugs into the back up drive.  I unplugged the cord from the printer and plugged it into my back drive.   My computer still did not recognize the back up drive.

As stupid as this sounds with my old Western Digital, which I think is about the same age as yours, it was VERY easy to plug the cable into the unit upside down by mistake; the lights would even go on, the computer just wouldn't register it. Make sure you're not doing that.

I apologize for assuming you'd make the same dumb mistake I would. I just had problem after problem with the cables - the plug on my unit itself is actually very loose and it's a struggle to keep a cable in.

there is no way to plug it in upside down.   I just checked.   and no need to apologize.

Does the drive have other connection options (some have firewire sockets as well as USB)?

If so giving that a try might get through to it.

If you can get thing to be acknowledged by a machine you can reformat it which would probably give the drive another lease of life.

it looks like there is another way to connect it to a computer, but I have no idea what I did with whatever cord it would take to do so, it such a cord came with the device.   This is also assume my computer can take such a connection, being a few years older than the device, that is far from certain.

that does not look like the kind of connection I have on the back up drive.

nope, its not that either.
