Hard drive crash is one of the prevalent computer issues that may have hit your entire work schedule at some point in time. Such catastrophes are undoubtedly a pain in the neck for the user. However, it does not necessarily mean data loss. In order to remedy this problem, you need to understand the underlying cause. The foremost solution is to stop using your affected drive and carefully plan out the next steps for data recovery. If the BIOS of your machine can still recognize the drive, you are more likely to have a driver issue. The problem usually surfaces after you install new software or new drivers in your system.
What happens with logically failed hard drive?
Typically, logical hard drive damage occurs at the file system level. These problems may be easy to deal with or may sometimes give you a nightmare experience. Logical drive issues can be as simple as a case of invalid entry in your file allocation table. In the worst cases, the file system on your hard drive would become severely corrupt. At this stage, you should avoid running a fix utility (ScanDisk or ChkDsk) on the affected drive. This would easily render all the recoverable data on your hard drive unrecoverable.
The most common error message that appears on your screen frequently in an event of logical drive failure is shown below:
‘The disk in drive <x> is not formatted
Do you want to format it now?
The error will show up when you attach an unformatted hard drive to your system or when the file system on the attached drive cannot be recognized by the operating system. In addition, when bad sectors are formed in some critical regions of the hard drive, the data on those sectors becomes unreadable or inaccessible.
Another common reason for logical data loss is repartitioning of hard drives. In a majority of cases, the repartition process fails to complete successfully due to damaged logical disk structure. In such circumstances, there’s high chance of data loss. Your system may become unbootable or give you errors at startup, such as ‘No boot device’, ‘Invalid partition table entries’, etc.
How to get data back from such cases?
Most logical cases of data loss are hard to deal with, but when resolved they ensure complete recovery of information from the troubled drive. A common misconception that surrounds logical drive failures is that the data is lost completely. However, the truth lies in the fact that data still remains on your drive. You can easily recover data after formatting or repartitioning hard drives through an efficient partition recovery software.
There’s a plethora of such tools in the market today that can help you fix any case of logical drive failure to recover your mission-critical data. These tools comprehensively scan the storage media to extract pieces of recoverable information from any damaged NTFS, FAT, or exFAT based volume or drive. Using these tools, you can also search lost or accidentally deleted volumes on your hard drive.
