How to Do Data Recovery: Important Rules for Successful Data Recovery

Updated on Sep 11, 2018 by Daisy to Data Recovery Solution


This tutorial shows how to use Data Recovery Wizard to recover lost data back. Please follow this tutorial to recove deleted, lost or formatted data back.

Before you recover lost data, you must keep in mind a very important rule:


The success of your data recovery depends largely on your adherence to this crucial rule. When we say to make no change to the damaged disk, we mean that you basically should do nothing on the disk. This includes the followings:

  • Do not try to delete folders or files from the Bad Device, even if you are able to see them and think that they are not damaged.
  • Do not try to save anything to the Bad Device.
  • Do not attempt to format or re-partition the Bad Device, not even with a program like fdisk or format. If the support people for these or any other applications tell you it's OK to format or re-partition the Bad Device, do not listen to them.

You will risk permanent data loss if you do not heed these warnings. If you already have made one of these mistakes, don't worry. Just don't make any more changes to the Bad Device. You can use the easy recovery software - Data Recovery Wizard trial version free to see if your data is still recoverable. And even if the Data Recovery Wizard can't detect your Bad Device, all is not lost. If your Bad Device is HDD, it is not detectable by computer's BIOS. It's URGENT for you to turn off the power of the device immediately! You will not be able to recover the device with any commercially available utilities, and you should consult a professional data recovery service provider.

When performing a data recovery we recommend that you proceed as follows:

  • Install the Data Recovery Wizard on a healthy Windows machine without the drive attached you want to recover from. Make sure you have sufficient space on the "good drive" for storing the recovered data. The machine on which you are running the Data Recovery Wizard on can have any of the following operating systems: Windows 2000, Windows XP, Windows 2003 and Windows Vista, Windows 2008, Windows 7, 8.
  • Shut down the computer and attach the drive you want to recover from ("bad drive") as a 2nd drive (Please see: How to install a hard drive?). You might need to jumper it differently. Make sure it is recognized correctly by the BIOS when starting up the computer. If you're not sure how to create a master/slave setup on your computer, there is an excellent article with detailed instructions on how to do so here.

    You can contact the drive manufacturer for assistance with installing their drive as a slave (secondary) device. Be sure that the primary drive is loading Windows.

  • Start Data Recovery Wizard.
  • When Data Recovery has completed and you are ready to copy the recovered files over to the "good drive", never copy the recovered files to the bad drive.
  • After copying all desired files shut down the computer and remove the "bad drive". Store the "bad drive" at a safe location.

We also recommend that you build a brand new system now if your bad drive has been severely corrupted. Use another device other than the bad one. Install the operating system, then install the programs from their installation CD-ROMS. Finally you can import the recovered data to the new drive.

Verify that you have got back all the data you need. Do not recycle the bad drive unless you are absolutely sure about all wanted data is in place. It is a good idea to wait for 4 weeks before re-using the bad drive. If the bad drive has any mechanical problem you definitely must not use it again.

If you notice that there is any mechanical problems on the drive such as bad sectors and irregular noises, you need to immediately stop the recovery and make a drive image first (You can use our Free Sector by Sector Backup software - EaseUS Todo Backup). When it is successfully created, you can recover from this drive image as the same as recover from the original drive. A mechanically damaged drive can fail entirely at any moment. It must be your primary goal to fetch all the raw data from such a drive as soon as possible. Making an image also reduces the drive load because each sector is read only once. Professional Data Recovery companies always make an image of the drive before trying to retrieve any file.

Occasionally, if you could not get data back with the Data Recovery Wizard, our lab will provide you with the service within 24 hours.

If you divert from the process described above, always make sure you:

  • Never install the Data Recovery Wizard on the "bad drive",
  • Never use the "bad drive" as the boot-up system drive (C:),
  • Do not have temporary files and folders use the "bad drive",
  • Never copy the recovered files to the "bad drive",
  • Make an image first if the "bad drive" has mechanical problems.
