For a tech savvy individual, you already know that hard drive failures are inevitable. Possibilities are that sooner or later it will happen to you or to someone you know. The good news is that there are lots of great recovery tools and methods that can be used to recover your lost data.
Connect the Drive to Another Computer
To start work on the crashed hard drive, remove it from the current laptop or computer and connect it to another laptop or computer as a secondary drive. The best way to do this is to use a USB to IDE/SATA adapter, but If you don’t have one available then you can connect the drive to another laptop or computer internally as a secondary drive. If you decide to use this option, please ensure that the machine detects the drive in the BIOS or you won’t be able to access it once the laptop or computer starts up.
Try Copying the Data to Another Drive
After you might have succeed in connecting the drive to another laptop or computer either internally or with a USB adapter, check to see if you can browse the contents of the hard drive. If you can, try copying the data that you would like to recover from the crashed laptop or computer. There is a huge chance or possibility that only the operating system is corrupt and the user data is still OK.
