How to connect 2.5 IDE hard drive to PC

| 117

2.5To connect a laptop hard drive to a desktop computer you have to use a Laptop IDE Hard Drive Adapter. You can easily find this adapter on the Internet for $10-$15. This adapter is very handy if you want to scan a laptop hard drive for viruses and spyware using antivirus software installed on a desktop PC, transfer data from a laptop hard drive to a desktop computer or create a ghost image from one hard drive to another. I also use this adapter if a laptop hard drive has failed and I have to recover data from it.

When you connect a laptop IDE adapter, a desktop IDE cable and a laptop hard drive to each other, make sure to connect pin 1 on the hard drive, pin 1 on the desktop IDE cable to pin 1 on the adapter. On a desktop IDE cable the side painted in red goes to pin 1.

On a laptop hard drive there are 2 groups of pins. One group has 43 pins and the other has 4 pins. The pin 1 is located on the side closer to the group of 4 pins.

After you’ve assembled everything together, connect the IDE cable to a desktop PC. Connect it to a free IDE connector on the system board. When you start the computer, you should see the laptop drive in BIOS and in Windows. You can treat this drive as a regular hard drive.

  1. @ jalascoo,
    It’s not very clear what you did with the laptop hard drive.
    Did you install OS on the laptop hard drive while it was connected to your PC? If that’s what you did, most likely it’s not going to work in the laptop. You have to install OS on the laptop.

    Here’s what you can do:
    1. First of all, test the laptop hard drive. Connect it as a slave to your PC. After that install HDTune software (free for personal use) and test the laptop hard drive.
    Select the drive you want to test (laptop drive), click on Error Scan tab and Start the test (do not check Quick Scan).
    2. If the hard drive fail test, replace it.
    3. If the hard drive pass test, install it into the laptop and reinstall OS.

    I have a laptop which failed to boot up. So I hooked up its hard drive on a desktop pc to reimage. Yet I found after I moved back the hard drive to laptop, I is not booting up. I know the drivers like NIC,Video, Audio etc are different. So I removed all the desktop NIC and Video driver before moving back the hard drive to the laptop.

    Any idea what else I need to modify so that the laptop can boot up?

    Thanks.

    I would test the laptop hard drive and memory first. It’s possible one of them failing.
