My wd hard disk is detected properly but problem was the spcific drive was not shown in my computer for wd external hard drive

from disk management Initialize it, format it, your done.

External hard drives don't need any program installed on your computer to run. Your operating system Windows, Linux should handle it as soon as you plug the usb in your computer. The programs included in your WD external hard drive are tools to backup your data.

If you try to hook up your hard drive to a Windows prior to XP, maybe your computer will not handle it.

It is always safer to safely remove your drive using the green arrow icon in the lower right corner of your screen. This way, the drive is shut down properly and you minimize chances of fails when you plug it again on another computer.

Hope this helps!

Most of the time, "self-inflicted" damage is EXCLUDED from W.D.'s "warranty" for the drive.
So, it depends on your sense of "ethics" whether to file a warranty-claim.

An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

Hello, Does your HD give a clicking sound when its connected with the PC. If so then the HD is in the dying stage . If not try going to safe mode connect your HD and try detecting and doing a check disk in the HD. But anyway its better you take the HD to a local computer electronics or Seagate service to immediately recover the data from your HD. Todays Hard disk are very sensitive, even the hard disk falls down slowly, it may result in some HD Failure. So keep your HD safe.

check the drive status on the disk management

if not shown ti may be physically damaged

Try connecting it to another computer, to see if your computer is the problem.

Try a different USB cable between the unit and your computer.

If it is still under warranty (one year?) then contact W.D. to get an RMA (Return Materials Authorization) -- then, ship the unit to them, for repair/replacement.

If the warranty has expired, open the case, disconnect the USB-to-disk-drive adapter, and connect the disk-drive as a "slave" drive in some desktop computer, to see if it can be properly "detected".

Note that W.D. has a "Customer Loyalty" program -- give them the serial-number from the disk-drive, and you get a good discount on the purchase of a new Passport from their web-site.

Have to check it in the Device Manager that the new device have been detected or not. It may happen that when the external HDD connects to the computer for the first time computer cannot detect it as it is not properly formatted in proper file-system. Open Computer Management and click on Disk Management and format the device correctly to operate.

if the disk is not in Computer Management then the disk has a major problem. it should be there but in black because u need to initialize it.

If the device is recognized and not listed as a driver in the Explorer, then the disk is not recognized as having been partitioned and formatted. You can use the Disk Manager to see if there is anything listed on the disk.
Start - > right-click My Computer -> Properties
In the management console, go to disk management and check your disks. The external disk should be there and then you can see the partitions and drives assigned to it.
If there is nothing on it, your MBR could be damaged, which needs to be restored.

Alternatively you could partition and format it, but then you'd loose the data on it, so that is a last resort.

I think a program called Acronis Disk Director Suite can restore MBR's. Have a look at this external hard disk troubleshooting article.

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)
