Solution 1. Recover Hard Drive on Another Computer
Sometimes it's just Windows OS corruption that makes your hard drive fail to boot. Great, you can just take out the drive from the dead computer and connect it to another computer. If you can access the hard drive normally, go ahead to backup hard drive data.
Solution 2. Put Your Hard Drive in a Freezer
What if it's the hard drive problem that disables the boot? Try putting it in a freezer. Many hard drives that stopped working can be brought back to life. It's not a permanent solution to fix a non-bootable hard drive, however, at least somebody says that it worked for about 20 minutes, which gives enough time for them to copy everything on the drive.
Solution 3. Copy Hard Drive Files from the Command Prompt
Or, if you had a Windows installation media at hand, try to boot Windows from the bootable disc or USB drive. Invoke Windows Command Prompt so that you can use robocopy to easily copy all folders and files on the selected drive. Enter the following command: robocopy C:\tools D:\backup\tools /e
- The /e modifier tells robocopy to include all subdirectories. This includes empty folders.
- robocopy will automatically copy hidden and system files. It will create new directories if they don't exist at the target location.

Frequently Asked Questions

- 2. Why cannot I recover 2GB data for free?
It is recommended to check the version installed is Free or Trial because they are different versions.
Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.
- 3. Why cannot the recovered files be opened?
A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.
If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.
- 4. Why isn't it suggested to recover the files back to the original drive?
The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

The Free version helps you save 2GB files, so verify the recovery quality of our product before purchase.
