Though hopefully not the case, you should be prepared (mentally at least) that the data on the drive is unrecoverable. With whats happening its a delicate situation. Check in the device manager ->disk manager and look what kind of drive it is showing up as. If it shows up in there that's really good. It might just have somehow got switched (by the OS) to the offline setting. All you would need to do then is initialize the drive (wizard will do all the work for you) and wait to see what comes up. Long as the data isn't corrupted you should then be able to use the drive again through the regular windows explorer.
If the computer will let you, run scandisk on and it might be able to fix the disk with just that. Even if it still doesn't work afterwords, it will report any unfix able errors it might have come across. Some of these errors you can still work on, while some basically say your disk is toast.
Not sure what kind of external drive you have, if the above fails or doesn't show up; another possible solution is to take the drive out of the enclose and hook it up directly to the pc. If the motherboard successfully identifies the drive you might be in the clear. Once you're booted into Windows check if its in the explorer pane, if not repeat the procedure about about adding the disk. If it works under this case, something in the enclosure is broken and you just need to replace that.
What I'm afraid that might happen is that one of these two methods will let you successfully mount the disk, but your data might not be there. It just shows up as a 0gb drive and will ask you if you want to format. This means your disk index is probably corrupted and unable to read the data on the disk now. If that's the case you're looking at data retrieval services; though if that is the case I know of a good freeware forensic disk program that could possibly salvage your data if the worst case scenario is what it has become. At that point contact me via email and I'll send you the info, you could also mail me as well if some other kind of strange behavior pops up.
Assuming that you're at least able to get back to the data, I would go to Seagate website and download their SeaTools diagnostic program. Run it on the disk and see what comes up, it could come up with the error that the drive is defective and must be returned (basically it gives you a generic message saying that the drive is dead and nothing you can do about it) or replace. It might be possible that we're able to get the disk readable and up and running, but you should run the diagnostics anyways to see if the disk is reporting any failures. A partially broken disk can still continue to function until you pass a certain threshold or you get a catastrophic failure. After completion it will usually say that your disk is fine, or that its replacing, or you should replace it before it does fail.

WD Elements SE Portable external hard drive doesn't show up on my computer?

I've had the external HD for about six months now and it had been working great until yesterday when it suddenly stopped showing up on my laptop (macbook pro). I've tried it on three different computers (mac and one of them running windows 7 and the other windows 8). I've been on google all day and I've had nothing to that works. I've tried computer management - disk management on both window computers and it's not there, well not in a way that works. It shows Disk 1 but with nothing in it and it says "not initialized" and when I try to I get an error message of "the request could not be performed because of an I/O device error". I really have no idea what to do. Any help would be greatly appreciated. Also I'm really trying to fix it without formatting it or losing anything since I have a lot of important things on the HD.
Thank you
I can't remember if it's mentioned above but I've tried different cables already and nothings changed on any computer

Do this...
â Connect to the Mac.
â Open Disk Utility.
** If the drive is not shown at left, it is a hardware defect. See below.
â Select the hardware name at left (NOT the partition name, but the brand, such as "WDC blahblah").
â Select the "Partition" tab.
â Under "Volume scheme" is "Current" and under that is a rectangle. Select the rectangle.
â Click the - sign to remove the partition, and click "OK".
â When that is done, click "Apply".
â Select the "Erase" tab and erase as "Mac OS Extended (journaled)" to use with Mac OS or as "MS-DOS" to use with Windows, and then click "Erase".
â When that is done, if it is for Windows, connect it to the Windows system, and format as NTFS.
** If the drive is not shown at all in Disk Utility, either the cable is bad, the case is bad, or the HDD inside the case is bad.
