DELL Diagnostic Error Code 2000-0142: When the hard drive is dying, you will get obvious symptoms such as constant data corruption, freezing when copying or saving data, long startup times and constant repair screens during boot. However, you cannot know for sure if the problem lies in the HDD unless you perform a Pre-boot System Analysis (PSA). Dell computers allow a complete PSA, also known as ePSA, that tests all system hardware.
These include memory tests, driving tests, fan tests, input device tests and HDD tests among others. To run ePSA on Dell, restart your PC and press F12 to access the start menu, and then select “diagnostic.” Following the symptoms mentioned, it is very alarming when users receive a diagnostic error that indicates a disk failure. This error shows the following information.
MSG: Hard disk 1: automatic test status failed 79 o Message: Hard disk 0 – N / S WX51E43XWS20, short auto test failed
Dell technical support can use the code and message given to help diagnose the problem. Do you want to keep trying?
This error will throw your PC into an endless loop on startup repair. So what does this error mean? And what are the solutions for this? This article will address this problem and try to solve it.
Simply put, this error means that the ePSA could not read the hard disk information successfully. By extension, your computer will not start or you will have trouble getting started because recovering information from disk is not reliable. However, Windows will attempt a system startup repair in vain. These are some of the various reasons why this error message may appear on your Dell computer:
Defective or misaligned wiring in the case of your computer, connecting your hard drive to the motherboard.
Damaged data or MBR (Master Boot Record) on the hard drive, causing the device to lock.
Device failure, in the form of mechanical damage to the hard drive. Overheating and mechanical shocks can lead to deformed plates, broken reader heads and broken spindles. This means that your data cannot be read correctly, hence the problem.
Solution Methods for DELL Diagnostic Error Code 2000-0142:
If you get this error, it means your unit is dead, or is dying and the fault is imminent. It is essential that you back up your data pending a complete failure. You can try to revive the disk with the first 2 methods below to be able to extract any important information. Remember that if the method works, you will need a hard drive replacement because 95% of the time, these hard drives cannot last more than a week after this error.
Method 1: Perform A Disk Check at The Command Prompt Using a Windows Installation Disk:
The Master Boot Record contains information about the location of your operating system and the kernel. This tells your computer where to load the operating system. In the case of a corrupt MBR, this method will attempt to recover corrupted data. If it works for you, we recommend that you back up your data to a new disk, since the error you experienced indicates an imminent disk failure. You will need a Windows disk (Win 7) for this method. You can find our guide on how to make a Windows 10 disk or a Windows 7 disk.
- Place the Windows 7 installation disc in the disk drive and then start the computer.
- Press a key when prompted (or press F8 at the start and choose the DVD drive from the start menu)
- Select a language, time, currency, keyboard or input method, and then click Next.
- Click Repair your computer.
- Click on the operating system you want to repair and then click Next.
- In the System Recovery Options dialog box, click Command Prompt.
- Type Chkdsk / f / r or command and press Enter to repair bad sectors and repair corrupt data.
Method 2: Reinstall Windows:
This method will also correct any corrupted Windows file, or any damaged or missing MBR data. Visit https://appuals.com/how-to-clean-install-windows-10/ for a guide on how to clean the Windows 10 installation. If you prefer, you can install Windows 8 or Windows 7. In case This works for you, we recommend making a backup of your data, since the error you experienced indicates an imminent disk failure.
Method 3: Replace Your Hard Drive:
If methods 1 and 2 did not work in any way, then your disk has experienced a permanent failure and will need replacement. Look for SSD (solid state drives) instead of HDD (hard disk drive) to avoid this disappointment in the future. Since hard drives use turntables and moving heads, they are more likely to fail. This usually occurs after 3 to 5 years of use.
If the system is under warranty, contact Dell support for the error and they will replace the unit. The manufacturer’s warranty generally covers a failed HDD.
Method 4: Wrong Hard Drive Slave and Try to Recover Data:
You can still try to recover your data if your disk fails methods 1 and 2. There is no guarantee. You will need an external USB HDD converter for a few dollars ($ 10). You can also connect it as a secondary unit (not the primary one that has the operating system) to another computer. Desktop PCs generally provide additional cables to connect another SATA drive. Use any of the methods to try to read your disk. If only your MBR sector or Windows files were damaged, you will discover that you can still read your HDD and access your data.
Data experts can retrieve your information by changing the reading heads or bringing your plate to functional reading heads. Either way, this is a precision process that will cost you a lot of money, so make sure the data you are saving is worth it.
