Hard Drive not responding

I have a problem, that the computer does not seem to be able to analyse the details on the external hard drive. Symptoms/ observations. 1. The power supply light on the transformer is on 2. Windows recognises that a USB device has been connected 3. Directory does not show up in the folders. 4. Regular quiet clicking noise can be heard from inside the hard drive. (A bit like it is trying to start up , but hasnt quite got the energy to do so) Any help greatly appreciated, as I dont want to loose all the data and dont want to send it back to the manufacturer with all the data on it.

The clicking sound you hear is unfortunately the death rattle of a hard drive. The sound is a regular click, click, click. This is because the heads of the drive can no longer find or read the sync track on the drive and usually means all the data on the drive is unrecoverable by external means. Hard drive labs can recover data from these disk failures but it requires them to dismantle the drive and that is usually a very expensive upwards of several hunderd dollars depending upon the amount of data recovered. You can purchase a replacement drive for the case and install it yourself if youare brave enough, for less than the cost of the complete package if you are good with a screwdriver.

My lacie drive fell off desktop and is not recognized as readable by my Mac. What chance do I have of recovering the data?

Inside that LaCie external harddrive's enclosure is a regular SATA harddrive.
The kind that fits in a desktop computer (3.5 inches in width), or laptop. (2.5 inches across in width)

Open the external enclosure (Case) of the LaCie, remove the harddrive, and install it into a suitable external enclosure.
(Laptop size, or desktop size)

The external enclosure has a USB cable also. Just plug it into any available USB port on your desktop computer.

Do I know for a fact that the harddrive is okay, and this will fix the problem?
No sir/maam I do not.

But IMHO this is the first diagnostic method to use.

IF the harddrive is a desktop sized harddrive, it could be installed in your desktop computer as a Slave drive.
However the above method is so much easier, and it allows your harddrive to be an external harddrive once more.

Inside the external enclosure of the LaCie external harddrive, is a small circuit board that the Harddrive plugs into.
It is this small circuit board that receives the damage in most cases.

If the problem is the Harddrive itself, a professional data recovery shop will;

A) Try a new, or good used harddrive circuit board.
Check to see if the harddrive's circuit board received the damage.

B) If the circuit board proves to be good then the next step is to remove the Platters inside.
The room used is a Clean Room.
A room that is 99.9 percent dust free. (In most cases)

The Platters are installed into the case of a compatible harddrive, that has the Platters removed.
Then as much information as possible is copied off.

There are other methods data recovery specialists use also.

[A Harddrive is built in a Clean Room. 99.9 percent dust free. The technicians wear a Clean Suit, that resembles what a doctor would wear in an operating room.
They enter the work area after going through a corridor, fitted with air jets at various levels.

If a harddrive is opened up in a room that is not a Clean Room, the harddrive's 'life expectency' drops to a day, or a few hours. The dust 'kills' them ]

Observe the other videos also.

Examples of both a SATA 2.5 external enclosure, and a SATA 3.5 SATA enclosure,
(The Harddrive's width is measured in inches. (2-1/2 inches for a laptop drive, 3-1/2 inches for a desktop drive)

SATA 2.5 external enclosure,

SATA 3.5 external enclosure,

Connect the external drive to another computer and observe if it's going to work perfectly on that computer.

Which ever the case may be, here is what you need to do on your computer;

Insert the external drive into your computer

Go to device manager.

Go to the name of the external drive.

Right click on the external drive and click 'Uninstall"

Allow the external drive uninstall from your computer.

If possible uninstall every other device under the "Universal serial bus controller (usb).

Once this is done, disconnect/remove the external drive from your computer.

Restart your computer.

Wait a while for the computer to boot computer. Also whatever you have uninstalled from the device manager, might install automatically. Which ever the case maybe, make sure your computer has finished booting or installing any device before you attempt to insert the external drive into the usb.

Now insert the external drive and wait for the computer to install the external drive, then observe if it will open this time around.

By now it should open. But if it doesn't open, please let me know so that I may direct you further on what next to do.

I wish you good luck.

My Western Digital External Drive is not working. When I plug it into my laptop it starts to run and shortly stops with one blinking light. It is not recognized by my mac.

Observe the device details to ascertain compartibilties. For example devices that are manufacturer for apple mac computers least get recognised on microsoft computers. usually the observation on the pheripheral device with mac logos is prior indication of likely incompartibilty to microsoft computers.

Myexternal hard drive wont boot and it says its unreadable or corrupted. maxtor 500gb tried a lot to resolve proble what exactly now i cant remember

You need to include info about your computer, and which format your external hard drive is: USB or Firewire. Are you using a Mac or PC?
"Boot" refers to the situation in which your hard drives sets up the operating system of your computer. I doubt this is the case. Do you mean that your host computer does not recognize the external drive?
If the latter is true, this can have many causes.
Also, did this drive work at some time? If so, with this computer, or a different one? The problem may be as simple as installing the proper driver, or at worst, the drive may be non-functional.
Most manufacturers of mass produced external drives, in the interests of being competitive, use drives that are not as durable as you would expect in a backup drive. Also, the interface in the case that houses the external drive often fails, so the drive itself may be OK. You can check this, but observe the following conditions:
1. You will void the warranty if you open the external drive case.
2, The warranty will replace the drive, but will not recover the data on that drive.
3. You can remove the external drive from the case and install it in your host computer to check it, if your computer is compatible with that drive. You need to know how to set the jumpers of that drive for your setup.
4. This can be a difficult and frustrating process. If the data on the drive is important enough, you have to decide if the cost to retrieve it is worth it to you.
Contact me if you need more info.

I want to open my hard disk because it cannot show on the computer.

The situation with a "lost" hard drive typically arises after Windows has been reinstalled or when a slave/external drive is moved to another computer.
If the drive/partition shows up in Device Manager and Disk management, but NOT in "My Computer", chances are that it is "only" the partition table that is missing or corrupt.

You can use a freeware program called TestDisk to repair the partition table and get access to your data again.
TestDisk will not change or delete any of your data if you follow the instructions below.

Try this to repair the partition table:

The newest version of Test-Disk, 6.11 is available here
Download the Windows version of TestDisk.
Unzip the downloaded file to your C: drive.
Open C:\testdisk-6.10\win > double click the "testdisk_win" icon.
The program runs in a command window and doesn't have to be installed.
Each of the steps (A, B, C etc) below corresponds to a new TestDisk window.
Use the keyboard's arrow keys to navigate.
A. At the first window, select “No Log” and press the <Enter> key.
B. Select which drive to analyse, choose “Proceed” and <Enter>.
C. Select partition type – Intel if it’s a PC then <Enter>.
D. Select “Analyse” then <Enter>. The drive will be analysed.
E. Select “Quick Search” at the next screen, then <Enter>.
F. Press “Y” if the partitions were created under Vista – “N” if not.
G. TestDisk should say “Structure OK”. If so, press <Enter>.
H. Select “Write” and press <Enter>.
I. Press “Y” to confirm.
J. Press <Enter>.
Close TestDisk and RESTART the computer.
The drive/partition should now be fixed and your data available again.

WD Passport 3200 isn't assigned a drive letter when plugged in

try to right on my computer and click on Manage
then click on Disk Management
Observe if you are able to see Drive 0 <- which is your internal drive in your computer.

Observer also if you are able to see Drive 1 <- this will indicate that the system recognise that an external USB drive was attached to it.

Right click on the area right next to the box that says Hard Drive 1 and see if you can find the wordings "Change Drive Letters and Paths".

If you manage to go that far, click on any of your preferred drive letters, for example Z: and then click OK. And then go to Windows Explorer or My Computer and see if Z: existed there.

USB WD 120gb external Hard Drive the My Computer Icon is missing

The "my computer" icon has nothing to do with the WDD hard drive. You do not say what the "other detail" is. Google on how to perform a System File Check and run that . If it repairs the system files then good, if not then run a chkdsk /R". That should resolve all issues. If you have further problems then tell us what operating system you are using and try and be more specific in what the problem/s are.
