Maybe, your hard disk enclosure is broken already, but your hard drive is still functioning. You can open the enclosure and try inserting your hard drive in your PC if it's still working so you can save your important files there.

To open your enclosure, copy the link below and paste it in a new tab.

I found this on this site. in case you havent seen it. It worked for me. Try this:

When I disconnected my backup drive and plugged in a USB drive the other night, my Windows drive letters got all wonky. D: became G: became F: became H:, and a bunch of my shortcuts didn't work anymore.
But it's easy to reassign the drive letters of your choice to add-on disks in Windows. Microsoft says you should log on as an administrator, and from Administrative Tools in Control Panel:
Double-click Computer Management, and then click Disk Management in the left pane.
Right-click the drive, the partition, the logical drive, or the volume that you want to assign a drive letter to, and then click Change Drive Letter and Paths. Of course things can get wacky if the disk is in use - by your computer or another on the network - so proceed with caution, you drive alphabetizer, you.

PC will not recognize the WD 750 drive. It shows in the device manager, it is detected with WD Lifeguard, but will not run any test, all fail. It is not detected by compmgmt.msc. It is over 1-year old and...

Most likely the drive is failing because it is in X-box format instead of a recognized PC format. Your most likely going to have to Partition the drive again and reformat it using a standard format.

New external Hard drive

Open up My Computer and see if there is a new hard drive listed there. It should be automatically detected by your computer, you just need to know where to find it.

Not Detected on PC

Since you say that it is detected in Device Manager and is shown as working properly, it would appear that the problem is that it is not getting a drive letter. Have you added anything recently that might take up a drive letter like a flash drive? If so, try removing both and then plugging the WD back in. If this is not the case or does not help, do this:

Assuming you are using XP.
Right click on My Computer and select Manage
The computer Management window will open, click on Disk Management
Do you see the WD in the window on the right?
Does it show a drive letter?
If not, you can assign it one by right clicking on it and selecting Change Drive Letter and Paths ...

If the WD does not show up in Disk Management, possible problems are:
1) USB cable is damaged, try another one.
2) USB circuits in the WD case not working properly, hard drive can be removed and put into another case.
3) WD USB case is good, hard drive is good but there is a loose connection inside. Open case and reseat everything.
4) WD USB case is good but the hard drive inside has gone bad (worst case scenario)

Laptop usb hard disk

I've had this problem many times with external SATA hard drive plugged into the usb. My 120gig hard drive takes significant power to operate it. On laptops with a long cable to the usb, I get the Tick tick tick sound and the light flash in concert with the ticking. On laptops with short cables to the usb, the hard drive works. On one desk top, the hard drive doesn't work on the front usb but does on the rear because the rear has no cables. The usb comes off the motherboard. Conclusion? Most likely a voltage problem from longer than usual cables from the motherboard to the usb. One solution is plug the hard drive in the rear usb. Another solution is buy a more expensive cable linking the hard drive to the usb. Or buy a shorter cable. More expensive cable may have thicker wires that won't resist the current. But I do not believe for a minute that the hard drive is faulty. I've seen it too many times and it has never been a faulty hard drive.
