Connect laptop hard drive to desktop computer

Yesterday my laptop failed to boot. Everything appears to be normal but each time I turn it on it hangs on Windows screen with a running bar. I cannot boot my laptop to the desktop. I tested the hard drive and it passed the test. I think that my hard drive is fine and the operating system is corrupted. I have very important files in my documents and I need to recover, transfer them to the desktop computer as soon as possible. How can I connect the laptop hard drive to a desktop computer?

It is nice that your hard drive passed the test. I think you have very good chances that your data is still good and you would be able to transfer it to the desktop computer. Here are some tips for connecting a laptop hard drive to a desktop computer:
1. You can use 2.5” hard drive adapter and connect the laptop hard drive directly to a desktop computer through the IDE connector on the system board. The desktop hard drive would be connected to IDE1 so you can connect the laptop hard drive to IDE2. After you boot the desktop computer the second hard drive would be detected and you can access it as a regular HDD. Now you can recover, transfer all needed files from the laptop hard drive to the desktop hard drive.
2. You can use an external USB enclosure for laptop hard drives. I think that would be the easiest and fastest way to access your data. You can find an external USB enclosure in any computer shop and it would cost you about $20-$30 or buy it on ebay for $10. After you remove the laptop hard drive, place it inside the enclosure and connect to the desktop or another laptop computer via the USB cable. It is not necessary to install any drivers for the enclosure if the desktop PC runs Winodws 2000 or Windows XP. If the desktop PC runs Windows 98, then most likely you’ll have to install a driver for the enclosure before you can access the hard drive. The USB cable and the driver usually supplies with the external enclosure. Now you can access the laptop hard drive as a regular drive on your desktop/laptop computer.
