"Two weeks back, I switched on my laptop and suddenly a message popped, 'hard disk failure is imminent' I ignored it at first but the error message kept reappearing. What do I do?"
While this is one sort of error you could face, hard drive failures occur in many other unusual ways as well. For logical errors, there are warning messages which you may conveniently ignore. For errors because of physical damage, you won't even realize when something went wrong, and failure was caused.
Hard drive failure means that the hard drive of your computer is not accessible, implying that the computer cannot reach or use the data, or is malfunctioning.
Hard drive failure can happen at any time however, there are various solutions available to recover data from hard drive.
Logical Hard Drive Failure
The logical hard drive failures appear as data corruption. Some files may seem infected or corrupted because you won't be able to access them. The most common warning signs of logical hard drive failure are missing files, failure of the system to boot, notifications indicating failure or inaccessible hard drive, or blue screen of death (BSOD).
Physical Hard Drive Failure
The physical hard drive failures are different, and most of the times these happen even before you realize them and can take action. Your hard drive will work till the end before shutting down, but then data recovery will be difficult. Hence, pay close attention to the subtle signs of physical hard drive failure. The most common warning sign will appear in the form of grinding or clicking noises. No doubt, this can indicate issues in other physical computer parts too, but, to be on the safe side, backup your data. Once done, shut down your PC, and take it to a professional data recovery service provider to avoid further damage.

There are generally two types of storage media for Laptop/computer: Hard Disk Drives (HDD) and Solid State Drives (SSD). While HDD relies on rotating discs and magnetic storage, SSD relies on flash memory similar to a USB drive.
If you have ever seen an opened hard disk drive, you might have noticed a bright circular area. This circular portion is made up of magnetic material and divided into billions of parts. This is called a hard drive platter. It is either demagnetized (to store 0) or magnetized (to store 1). Magnetised storage is used because the data remains stored even when you turn off the computer.
SSD is used for the same purpose as that of HDD, but the functioning of SSD is different. Instead of magnetic plates, SSD uses a grid made up of electrical cells (flash memory). These cells receive or send data along with storing data. The grid of SSD is made up of numerous sections known as pages, and these pages are combined together to form blocks. Data is stored on available pages.
To monitor your hard drive usage, open Task Manager by right-clicking on the taskbar or by pressing Ctrl+ Alt+ Delete on your keyboard. Here, under the disk tab, you'll see your drive performance. If you are having issues with your drive, there is a chance that the disk performance will be somewhere around 100%.
Just as the name suggests, ‘I/O device error’ occurs in your hard drive when your computer is not able to execute input or output functions on the hard drive. You may receive error messages such as “Only part of a readprocessmemory or writeprocessmemory request was completed” or “The request could not be performed because of an I/O device error.”
The 301 hard drive error usually indicates that the hard drive is expected to crash soon and if that happens, it might take all your data with it. In such a scenario, the first step should be to back up your data. You may encounter this error at the time of computer boot.
This problem occurs when the BIOS is unable to detect the hard drive of your computer. You will receive an error message, and your computer will fail to boot in the first place.
Note: Most of the times, unrecognized hard drive error is not possible to fix virtually. You need to contact a data recovery service provider for professional help and recovery of your data.
If you suddenly hear occasional grinding or clicking noises from your hard drive, it may be a sign that your hard drive is proceeding towards failure.
Note: The grinding or clicking noise is not always a sign of hard drive failure. It could be from the fan of your computer too, which is present to avoid overheating.
It is known that the Blue Screen of Death (BSOD) occurs when there is some critical or fatal system error. This critical error can be a hard disk failure. Your computer may immediately start rebooting in the safe mode after blue screen. If this fails or your computer is not able to perform this action, then it can be a sign of hard drive failure.
When a partition of the drive is deleted or lost, you may not be able to view its traces in Windows Disk Management. You might lose or overwrite all your data if you try to tamper with the unallocated space created by lost or deleted partition.
When you receive a message that says, "Windows Detected Hard Drive Problem," it may indicate a failing hard drive. You may lose data, your system may get corrupted, or your computer may stop booting.
There is a chance that you may have lost hard drive data during repartitioning. Repartitioning a hard drive includes shrinking or increasing one partition, reallocating its space, creating a new partition, and deleting the old one. During this process, some files may be lost and you may encounter other errors such as "Exception Processing Message".
Note: If the partition table is damaged or altered during repartitioning, it can also lead to an unbootable computer.
Bad sectors mean that some storage on your hard drive is not accessible and defective. It is obvious that any operation on this cluster will not show any results as the hard drive won't respond.

Hard drive error 2000-0146 leads to PC freeze, a slow running of programs, inability to access services and files, and computer crash. It can also result in corruption of the entire computer.
If you encounter an Error 0142, it means there is some serious issue with your hard drive, and it has failed to clear self-test. This issue can lead to hard drive failure, CPU crash, operating system crash, and many other issues like these.
Hard drive head crash indicates that some physical damage was caused when the spinning platter and read/write head came in contact. In case of this error, either you won't be able to boot your computer or you'll hear grinding and clicking sounds.
Hard drive failure is inevitable. These failures occur due to various issues such as physical damage, wear, and tear, logical damage, virus attacks, overheating, electrical failure, mechanical failure, human errors, or manufacturing defects. Sometimes, even the new laptop that you buy may have existing manufacturing errors on the hard drive. At other times, it is possible that some file is corrupted because you shut down the computer when your computer was accessing the file. There are numerous other ways in which hard drives fail. Hence, it is necessary to pay close attention to warning messages, clicking sounds, and overheating issues. And when you encounter these issues, always contact data recovery professionals to avoid permanent data loss.
