A Real Case of Hard Drive Failure

There is a user who asks for the best software for data recovery from the possibly failed hard drive in the forum:

Have an older 40GB IDE drive here that is having issues since an unexpected power issue in the home. The drive is recognized by the BIOS, and Windows sees the drive and assigns a drive letter - but indicates that the disk is unformatted when you try to access it. It was formatted with NTFS. What's the best software to try and attempt data recovery nowadays? Can anyone recommend something good?

the disk is not formatted

In this case, the user can see this drive in the computer, but when he tries to access it, the system prompts that the disk is unformatted. That is to say, his access to the drive is denied. So he wants to get the best software to recover data from damaged hard drive.

Part 2: Get Ready for the Recovery

How to recover data from a hard drive when you’re in face of hard disk failure? This is a question bothering lots of people. Certainly, you all want to get the best software to recover data from the damaged hard disk; but as ordinary users, you also care about the data recovery prices, so you would ask “how much does it cost for data recovery”.

After taking these factors into consideration, I think I am obligated to introduce the best software to you and then discuss the price and how to recover data from crashed hard disk.

Before the recovery, you should confirm the following things:

  • Where do you want to do the hard drive failure recovery (on Windows or on Mac)?
  • Whether the computer can be started successfully or not after the hard drive failure?
  • How many files do you want to recover (less than 1GB or more than 1GB)?

Tips for making a decision:

  • To recover data on Windows, you need MiniTool Power Data Recovery; to recover files on Mac, please choose Stellar Data Recovery for Mac.
  • If computer boots successfully, please choose a proper edition; if you can’t enter the system, please resort to the bootable edition (embedded in some paid license).
  • The free edition is enough if you have no more than 1GB of data to recover; otherwise, please acquire a license. (Of course, you can try the free edition first and then decide whether to get a license for advanced edition or not)

Part 3: Use the Best Software to Recover from Hard Disk Failure

In this part, my theme is – the steps to recover data from a failed hard drive. I will explain this from two perspectives:

  • How to perform dead external hard drive file recovery
  • How to recover data from a dead internal hard drive
Tip: As for how to recover data from hard disk which is not detecting, please read External Hard Drive Doesn't Appear – How To Fix & Recover Data; it tells you not only how to get back lost data, but also the effective ways to fix dead hard drive.

Here, in the following content, I will take the Free Edition and the Personal Deluxe license as an example to show you how to recover from hard drive failure on Windows in 2 cases.

Case 1 – Recover Data on a Working Computer

Step 1, you should install the MiniTool Power Data Recovery on the local drive of the working computer. Then, run the software and start feeling its power.

install the recovery software

Attention!!!

Please don’t choose the drive that includes lost files waiting to be recovered as the destination for the installation, in order to avoid data coverage.

Step 2, in the main interface, take a look at the options located on the left side. Then, click on the one that is most suitable for your case (taking “Hard Disk Drive” as an example).

select an option

Here, you need to select the drive that is failed from the list. Afterwards, please click on the “Scan” button to search the lost/deleted files. Then, wait for the full scan.

Step 3, after the scan has been finished, a lot of files and folders found by the software will be listed in order. At this time, you’re expected to browse them carefully so as to pick out which are the ones you need and which are not. At last, please click on the “Save” button to recover them to another drive with enough free space.

Case 2 – Recover Data When Windows Won't Boot

If you can’t enter your OS, as usual, you’ll not be able to finish hard drive failure recovery by using the above method. Under such circumstances, you need the help of MiniTool Bootable Builder (which is a snap-in WinPE Bootable Builder included in some advanced license). Now, I am going to show you how to do the recovery work with the help of this tool.

Step 1, you need to find another computer that you can work on. Then, get a license that includes a bootable builder (take the Personal Deluxe as an example). After that, please install and register the software properly.

Part 4: Signs & Causes of Hard Drive Failure

Here, in this part, I’d like to invite you to learn more about hard disk failure.

What Happens If Your Hard Drive Fails

Do not think hard disk failure will never happen to you. As a matter of fact, it happens more often than you may think. The failure could be caused by a lot of factors, which can mainly be divided into 2 types:

  • Hardware failure
  • Software failure.

Either way, your data may still remain on the drive, not really lost. Besides, there is still hope for the recovery of your precious gigabytes of data that you have kept on the hard drive, only if you choose a correct data recovery solution.

Warning Signs

  • Files become messy codes or print out messy codes.
  • The name of files or folders is changed automatically.
  • Files or folders disappear for no reason.
  • Frequent/mysterious error messages, accompanied by typical activities like moving files.
  • Frequent, but irregular program crashes or disk errors.
  • A very long waiting time before accessing files and folders.
  • Strange noises coming from the drive, such as clicking or humming.
  • The overall strange behavior of the hard drive.
Tip: I have another post which tells you how to deal with a clicking hard drive.

Top 6 Causes

  1. Human errors. Both modifying settings improperly and wrong operations are the potential threats to a hard drive failure.
  2. Heat. The poor ventilation or fault in the CPU fan could easily lead to abnormal heat, resulting in hard disk failure.
  3. Electronic failure and power surges. Unstable power supply, too high or too low voltage will cause a hard drive to go bad.
  4. Internal or mechanical fault. This includes bad sectors/blocks, moving parts degrading, virus attack, etc.
  5. Files corruption. This could be caused by shutting down the computer improperly, closing programs accidentally, using faulty applications and software conflicts.
  6. Firmware faults. This happens to new hard drives when manufacturers sell the device to customers without testing it carefully.

Some people can’t figure out whether their hard drive is failing or has been failed; they may ask “how to check if my hard drive is working properly”. On this occasion, a hard drive test is necessary; they should do the test and analyze the result carefully.

Part 5: Conclusion

Hard disk failure is not so horrible. When you, unfortunately, come across hard drive failure, please remember to calm down first. Then, take proper measures to finish the hard disk failure recovery as fast as you can. Believe it or not, you still have a great chance to recover all your lost data from HDD.
