Safely remove the storage device from your system. This data backup is necessary because while resolving the error code 2000-0142, you may have to format the internal disk drive. 

Let’s Resolve the Issue

Method 1: Test the Internal HDD or SSD

It seems that you know how to take out the internal HDD or SSD. So, you cannot test the internal drive without a SATA casing. Open the screws and set up the disk drive into the casing. After that, move over to the other computer and plug in the casing. Run the diagnosis and check whether the error code 2000-0142 appears or not.

Visit any computer and its accessories retail store and purchase the same disk drive. After opening the package, take out the old drive and replace it with the new one. After that, with the help of the bootable storage device, install the OS. 

Method 4: The Data Recovery Process

As usual, set up the SATA casing and run the recovery process. Hopefully, you will recover more than 80% of the data. 

Method 5: Resolve Internal Hardware Faults

A few integrated copper pins come with every laptop and desktop computer. These copper pins provide the connection to access the data in the HDD or SSD.
