How to Retrieve Data from Hard Drive (Free)



This article includes step-by-step instructions to recover lost data from hard drive free. Data loss is a very common issue, as almost everyone faces the problem at some point of their lives. Successful hard drive recovery is important to everyone, as no one wants to lose important data. If you are experiencing data loss issue on hard drive, you are lucky, you can follow this guide to retrieve lost files and partitions easily and safely.


Main causes of hard drive data loss


It seems that data loss is unavoidable even though you've taken proper precautions to protect data. Files stored on hard drive may get deleted or formatted, and the storage device may get broken. Moreover, only few users are careful enough to back up files in time. Thus most of us will have to face data loss issue and learn how to recover them. The follow part explains common causes of data loss related to daily lives. Once you have this insight, you can learn how to prevent data loss and how to get back lost data from various devices.


Accidental deletion


The top cause of data loss is deleting files which are not backed up. Every day we create, edit, update, save and delete files, which are very common parts of working content. Thus it is natural that sometimes we delete wrong files by mistake. We are all human and we do make mistakes and that's the reason why Windows provides Recycle Bin. However, there are situations that we cannot restore files from Recycle Bin. In that case, we should recover deleted files using data recovery software. Here are some scenarios that deleted files are not put into Recycle Bin:

  • Files are deleted from devices that do not have a Recycle Bin, such as USB flash drive, SD card and Network.
  • The deleted file is larger than the capacity the Recycle Bin can hold, and it will be deleted directly by passing Recycle Bin.
  • Files or folders are deleted by keys Shift + Delete.
  • Delete files using commands in Windows Command Prompt
  • Files are permanently deleted from hard drive by third-party software
  • Files are deleted from Recycle Bin or the Recycle Bin is emptied.
  • Error occurs during Cut & Paste process
  • An entire partition is deleted

Disk or partition formatting


Formatting process wipes everything on the partition or disk being formatted. People often format hard drive or partitions for a variety of reasons such as install system, change file system format or repartition a hard disk. Here are some situations you may perform disk formatting.

  • Partition a hard drive. When you prepare a hard drive for storage purpose, you'll create partitions on that disk. The partitioning process formats the disk and deletes everything.
  • Change file system format. There are various file system types you can use such as FAT32, exFAT, NTFS, EXT4, etc. Most of times, the only way to convert files system type is formatting the drive.
  • Repair corrupt drive. It happens that your drive may turn to RAW or reports errors like "The parameter is incorrect". Some may suggest CHKDSK to repair the disk, but that cannot fix all such errors. The best solution is formatting corrupt disk.
  • Install operating system. Installing system formats system partition and then writes system files.

Hard drive logical errors


Logical errors on hard drive usually mean corrupt disk or partition. There is not physical damages on the disk in term of physical components, instead there is something wrong with the file system on it. Data on the corrupt disk is no longer accessible. Its file system type might be RAW if you check it in Disk Management. When you try to open the disk in Windows may get error messages like:

Disk is not formatted. The disk in drive H is not formatted. Do you want to format it now?
Location is not available. G:\ is not accessible. The file or directory is corrupted and unreadable.
Location is not available. J:\ is not accessible. The parameter is incorrect.

Virus and malware infections


New virus and malware keeps popping up to attack computers every day, putting your data at risk. Being connected to the Internet is not totally safe, as there are too many types of viruses to safely bypass their attack. The main target of virus is stealing, damaging and deleting business or personal data. For example the WannaCry Ransomware launched a worldwide cyberattack in May this year and numerous businesses and individuals suffered from data loss. To protect data from damage or loss caused by virus, you should install anti-virus software and create a proper backup.


Mechanical failure of hard disk


Hard drive is one of the most fragile parts of a computer, as it breaks down more often than other components. A hard drive contains too many moving mechanical parts, and it is very easy to get physical damages. Once a hard drive gets severe bad physical damages, you'll have to spend large amount of money to recover data from the hard drive. Let's see some cases of the physical failure of hard drive.

  • Bad sectors. Hard disk bad sectors can be the natural dying or external damages. Hard drive containing bad sectors will become very slow, freeze computer or even cannot be recognized. Thus it is not possible to access data if there are too many bad sectors.
  • Firmware corruption. Firmware is embedded in physical hard drive, which is responsible for hard drive operations such as manage interactions among other components. When started up, hard drive loads data from firmware area into RAM, then allowing the drive to report on readiness. If firmware fails, the drive might not be deleted by computer at all.
  • Electronic failure. It usually refers to problem on controller board on hard drive. Any data on that hard drive will be inaccessible with the problem unfixed.
  • Faulty heads. Hard drive heads works for read and write data and they can get damaged due to aging, impact or crash. Faulty heads may cause bad sectors, scratches platters, data loss, etc. In general, you can hear clicking or grinding noises once the hard drive is powered.
  • Impact due to being dropped. Hard drive, especially external hard drive tends to suffer from impact such as being dropped. In most cases, the hard drive will be badly damaged.

Other causes of hard drive data loss


Aside from causes mentioned above, other reasons of data loss on hard drive can also account for the issue:

  • Sudden power failure. Power outages or power surge happens when you are writing a long article or the hard drive is transferring data, you'll lose the unsaved data and the hard disk may turn into inaccessible. Besides, sudden power failure also poses a risk to hard disk heads, causing bad sectors.
  • Computer theft. It is really painful if computer is stolen or lost, as the danger exists that someone may steal sensitive files on your PC. Thus you may need to encrypt important data and keep multiple backup copies.
  • Damaged due to spilled water or coffee. Electronic products do not like liquids, which is true of hard disks. If you spill liquid or dropping hard disk into water, you run the risk of losing all data on that disk.
  • Disasters. Disasters like flood, fire or explosion rarely happens, but it is able to completely destroy both hard drive and computer. Thus many experts recommend remote backup and cloud backup.

What to do when you experience hard drive data loss


Hard drive recovery is possible when hard drive fails and many times hard drive recovery software is able to recover data. But you should protect both hard drive and lost data from further damage or data overwrite. Below are some recommended strategies you should know when you experience hard drive data loss problem.

  1. If lost files were stored on system partition such as desktop, you should shut down computer, unplug the hard drive and connect it to another PC. Do not try to reboot from this hard disk if you want to perform data recovery. If there is not extra computer, you should retrieve data from the hard drive in Pre-OS environment.
  2. If the failed hard disk does not contain important data, you can try CHKDSK to repair disk errors or perform a system restore. If the disk is no longer repairable, you can replace it with a new one.
  3. Do not save any new data or install applications to the hard drive where you want to retrieve data, as those actions are likely to overwrite lost files.
  4. If the disk failure is caused by corrupt files system, never format the disk even though Windows prompts to format. Apart from that, do not try disk check either. Both formatting and CHKDSK may lead to unsatisfied recovery result.
  5. Do not try to repair bad sectors by using disk check or bad sector repair software on a failed hard disk. Repairing bad sectors will cause permanent data loss. You can use professional disk image software to image the hard disk to a healthy drive, and the image process can be set to skip bad sectors.
  6. Never open the disk case by yourself. Professional data recovery center is able to recover data from broken disk by opening it and reading data from platters. But this should be done by professionals in a dust-free environment. If you open it by yourself, data on the disk will be destroyed permanently.
  7. If you want to recover data from hard drive on your own, you should choose a proper recovery program which should be reliable, easy-to-use and efficient. If you are new to hard drive data recovery, read the user guide or contact technical support for help.
  8. If your hard drive gets badly damages, for example, it cannot be recognized by computer, makes noises or freezes computer, data cannot be recovered by any software and it should be send to a data recovery company.
