Scanners and cameras obtain images and input them into a computer. Therefore, scanners and cameras perform the opposite function of a printer, which outputs data and images. TWAIN device drivers are an older technology driver model for scanning images into a computer. Windows XP replaces TWAIN with the Windows Image Acquisition (WIA) interface for both scanners and cameras.

Because scanners use the same underlying technology as cameras, the two are grouped in Control Panel under the Scanners and Cameras utility. These devicesdigital cameras, digital video cameras, scanners, and any other image-capturing devicesare largely Plug and Play. They install upon detection by Windows XP. After it is installed, you can download images from the device into any folder on the computer using the Scanners and Cameras Wizard. The default folder for images is the My Pictures folder, which is contained within My Documents. Most cameras and scanners are sold with accompanying software that provides additional image management, for example, a scanner often comes with fax software, copy software, or optical character recognition (OCR) software. The image that is input from a scanner or camera is simply an imageit does not function as text until it has been interpreted by an OCR program. If the scanner is used to pass the image through the computer to the printer, it is always rendered as an image of the original document.

Exam Alert

Device driver installation requires administrative rights When you connect a scanner or digital camera, Windows XP automatically recognizes the device a majority of the time. However, if you do not have the appropriate rights, Windows XP does not install the driver.

Cameras and scanners do not always appear as icons in Windows XP if they are not connected, or if their power has been turned off. Power-saving features on many cameras force them to shut down after a certain period of time; therefore, if an icon does not appear as expected, you should check the device to see whether it is turned on. Step by Step 8.1 discusses how to install a digital camera or scanner that connects via a Universal Serial Bus (USB) port.

Step by Step: 8.1 Installing and Testing a USB Digital Camera or Scanner1. | Start Windows XP Professional and log on as a member of the Administrators group.


2. | Plug in the device to the computer's USB port.


3. | A Plug and Play image-capturing device prompts the Scanner and Camera Wizard to begin, and the device driver installs automatically. Otherwise, click Start, Control Panel, Printers and Other Hardware, Scanners and Cameras. In the task pane, click Add an Imaging Device.


4. | Click Next to bypass the first screen.


5. | Select the device's manufacturer in the left pane, and then select the device model in the right pane. Otherwise, if you have a specific manufacturer's driver to install, click the Have Disk button.


6. | Click Next. If the device is not connected or not turned on, Windows XP prompts you to connect the device and select the port.


7. | Click Next.


8. | In the text box provided, type a name for the device. (A name may already be in the box, based on the information the wizard has gathered.)


9. | Click Next. Click Finish to complete the installation.


10. | Right-click the new device icon in the Scanners and Cameras utility, and select Properties from the shortcut menu.


11. | Click the Test Camera (or Test Scanner) button. Windows XP attempts to communicate with the device and then indicates whether the test was successful.

It may be hard to believe, but a completely dead hard drive may be the best option for a hard drive failure. When your drive is dead, it could be a problem with the computer power supply or the cables, or the drive itself could have just stopped. Either way, the drive is no longer accessing its platters and writing over or corrupting your data.

Hard drive recovery is necessary for failed drives in computers without scheduled backups.

If the drive makes clicking and grinding noises when it starts up, then shut your computer down immediately and contact one of our certified technicians to have your data preserved. Those clicking and grinding noises indicate damage to the read/write heads of your drive, and that is a mechanical issue that an expert should fix.

If you turn your computer on and it makes a series of beeps, then turn it off and give us a call. The key to understanding how to recover data from a hard drive is understanding how to preserve what data you have.

The operating system on your computer is constantly scanning, accessing, and writing data to your hard drive. When your hard drive starts to fail, your operating system could wind up interpreting bad sectors as blank sectors and start writing to them. That means that your drive will sustain more damage and you will lose more data by the second.

Open up your computer and make sure that the power and data connection cables for your hard drive are plugged in and working. Look at your cables and make sure that they are not frayed or damaged in some way. It is always best to start with the obvious things first when you are trying to figure out how to recover data from a damaged hard drive. If you are having problems opening your case, then check online for the instructions. You should have no problem finding a good video that will let you know how to open your computer.

When you first turn on your computer, a message will flash for a few seconds that will tell you what button to push to access your computer’s BIOS. Press that button and then follow the on-screen instructions to find your hard drive listing. If you want to learn how to recover a hard drive, it is important to first make sure that the computer can see the drive.

If you see your hard drive listed in your BIOS, then you have a chance at being able to recover your drive through your operating system. If your drive is not there, then turn the computer off and open the case. On the back of your hard drive will be a power cable and a data cable. Make sure they are both plugged in properly. If they are plugged in, then replace the data cable as a precaution. If your BIOS can see your hard drive after replacing your data cable, then you probably just solved your problem. If it does not see the drive, then you will need to move on to the next step.

To recover hard drive data safely, you need to connect your hard drive to a second computer that has a working operating system. Remove your damaged hard drive and put it in an external enclosure that can be connected to a second computer through a USB port.

When you connect the hard drive to a second computer, you will be able to:

As certified hard drive technicians, we know how complicated these little devices are. We understand the platters, the read/write heads, and the circuit boards. That is why we are telling you that opening your hard drive to try and retrieve your data is a bad idea. There are many different moving parts in your hard drive that you could damage, and you may lose all of your data for good.

Your best approach is to give us a call and we will quote you a price on retrieving that data for you. Even if the platters in your drive are damaged, we can still recover your data for you. If all of the safe options have been exercised, then we strongly suggest that you call in the experts and let us retrieve your data for you.
