What is a dead hard drive?

Hard disks are an essential part of a computer as they allow you to store and access your valuable data. When it comes to hard disks, this includes internal hard drives and external hard drives. However, just like electronic and mechanical devices, hard disks tend to die or crash over time.

In this situation, the drive will stop working entirely. Perhaps your computer doesn't recognize or show it up. You probably see a file icon with question mark on Mac or receive an error message saying your PC has no hard drive. If the failed hard drive is the system drive, your computer will act strangely, even worse, it won't turn on.

Symptoms of physical and logical hard drive crash

Hard drive crash can be broadly put into two groups: physical and logical. As different kinds of data losses should be dealt with different types of data recovery means, initially you should confirm whether the hard drive is damaged physically or logically.

Physical hard drive crash: When you hard disk is damaged by heat, moisture or shock, etc., it can cause physical failure. If there is a physical crash, you will hear the licking, whirling or other grinding noises form the drive. Physical damage can make hard drive data recovery incredibly difficult, but by no means impossible.

Logical hard drive crash: In the event of physical hard drive crash, you will receive some error message when accessing the hard drive. If the hard drive is an internal one in a computer, the computer may fail to boot up as normal. Fortunately, logical data recovery is much easier to perform.

Chances of crashed/dead hard disk data recovery

Don't worry! Unless the corruption occurs within the files or results from hardware problems, you can recover lost data from broken hard drive at the most time. Because if the crashed/dead disk refers to the corruption of file directory and partition table, the operating system just can't find the location of the stored files and the data still keep intact.

So in order to get the best possible chances of recovery on a dead hard drive, you should avoid running the hard disk and look for fast help from professional data recovery software.

What's the causes of a dead hard drive?

Here are some common causes of a dead hard drive in detail. Learning about them can help to prevent hard drive failure in the future.

  • Firmware or manufacturer faults. Firmware or manufacturer on a hard drive is software that is responsible for many major functions of the disk including accessing the data, as well as reading and writing to the drive. If the the firmware of a hard drive is damaged, all files on the drive will be inaccessible.
  • Electronic failure or power surge. A power outage may do harm to your computer and shorten the lifespan of storage devices. If the power is out while working on a hard disk, the heads for recording and reading data will be damaged. As a result, the operating system fails to locate all files on the hard drive.
  • Mechanical or internal failure. This issue may occur on a hard disk when its moving components stop functioning due to stress or wear. If your hard drive experience a mechanical failure, its read/write heads will be off track, which prevent the drive from accessing users data.
  • Corrupted files. Corrupted files will happen on modern computers with no good security measures in place. Usually, files become corrupted when being written to a disk. If your computer loses power or crashes while saving or creating a file, there's good possibility that the file will become corrupted.
  • Human errors. This is the leading cause of hard drive failure. It's possible that you may accidentally delete any system file which is essential to boot a hard drive when you think it could be malware or junk. Furthermore, there are some indirect human error which will make a hard disk crashed or dead.
