My external hard drive doesn't show up on under my computer?

First make sure the external hard drive is powered on.  I know that may seem like common sense but the simplest things are often over looked.  Next if your hard drive came with software you should install that.  If those things do not work go to start, control panel, in category view go to printers and other hardware, from there you will see something on the left side that says add hardware.  Go to that and follow the on screen instructions.  If you are in classic view just go to add hardware.  You can change the view on the left side of the screen.  After you have installed it restart your computer.  if there is something wrong you may need to reinstall something.  To check if something is wrong go to control panel again, in category view go to performance and maintenance then go to system.  In classic view just go to system.  Once in system go to the hardware tab then go to device manager.  Look for your external hard drive in the list of hardware installed on your computer.  If there is a yellow exclamation mark next to the hard drive then something isn't working correctly.

Most external hard drives are just an internal ide drive with its own power supply. You should be able to remove the drive, set it as slave and install it in your PC. This is pretty simple. If the drive is still ok, you can then recover the data.

Make sure your hard drive is formatted with the FAT-32 system.  Check the file name.  If it begins with a period, it will be hidden.\n\nAlso, check to see what type of extension the image has.  Mac OS X is tought to ignore some file types, mainly for it's HFS formatting.  I can't think of any case in which this would happen, but it's worth a shot.  Open Terminal and type:\n\ndefaults write com.apple.finder AppleShowAllFiles TRUE\nkillall Finder\n\nThat will show all of the hidden files.  If your image appears here, you may have to go back to your PC and resave them to a standard format\n\nJust retype the stuff in the Terminal, except put FALSE instead of TRUE

Just click on start on the bar at the bottom of the screen and click on my computer. Then double click on the hard drive which is usually C:

Is that a brand new external hard drive? If it is you normally have to partition it before your computer can easily detect it. You can use partition magic 9. It might probably have bad sectors too, you can use norton disk doctor to check it. If you think it really has keylogger or worm viruses then scan it using your updated(virus definitions) antivirus software. If the problem still persist, transfer all files to another computer (b sure it has the latest firewall and antivirus update) if you can, then reformat that drive using partition magic. Good Luck!

unbend a paper clip and stick the paper clip into the small hole in the front of the drive. that should release it

Sparky's answers would be right, if your computer just "couldn't see" the drive, but that's not your problem.  The drive is being recognized, so you've got a malfunction with either the drive itself, or the external case (probably the case's power supply).  \n\nDrives are "recognized" by Windows if their IDE cable isn't plugged in properly, or they don't have SOME power coming into them.  So, you have another problem.

As long as the hard drive is plugged in and it shows up in your computer's BIOS (and is given a drive letter) then it doesn't matter where it is... or what enclosure it's contained in.\n\nIf you're using Windows, you should be able to right click on that drive and choose "Format".

check the cables and power. those are the most likely culprits, especialy if the computer has been moved or jarred.  failing that go into bios and see if the computer recognizes the hard drive as there and can read it.  if you need files from it, attach it as a slave and see if you can access it....if not its probably a screwed pooch from a virus and needs to be replaced.

go to my computer.. Drive letters will be listed there according to ur partitions..\n\nwithout hardisk connection, u cant boot into windows..\nif u r in windows, then ur hard disk is working and can access it thru My Computer..\n\nIf u connected one more hard disk and wanna access it, u can access thru My computer..\n\nbut if the drives are not displaying:\n\n-check the jumber settings of the second hard disk.. set it as slave..\n\n--check whether it is properly plugged(power/data cable)..

You either hook it up to a USB port or Firewire port(IEEE 1394). Then you install the driver for it, and after you do that, you will find it (it will be name :C, :D, etc) in My Computer. They work the same way as a regular hard drive, but its connected to the computer in a different way. \n\nInfo on Hard Drives:\nhttp://computer.howstuffworks.com/hard-disk.htm

Is the drive USB or firewire? You may have a bad port on the desktop. To check this:\ngo to the apple menu in the top left corner\nchoose about this mac. when the window pops up, select more info...\nthis opens System profiler\nclick on usb and firewire to see if they register. If it says nothing, there's your problem.\n\nIf all ports are working, try this:\ngo to applications - utilities and open disk utility\nplug in your drive and see if it appears\n\nif it still doesn't appear, choose mount drive from the menus at the top while in disk utilityq

Set the jumpers on the drive to master (this is for any drive, not just for a WD).  Plug the power into it then connect the drive via your controller (I trust you mean external controller) to a USB port.  It should work fine.  As an extra hint, you can also use the external setup with a laptop drive - good capacity and much smaller.
