Why Do You Need to Repair a RAW Disk

Many computer users have reported disk errors when they tried to access the disk. And the most frequently reported one among them is that Windows notify "The drive in the disk is not formatted. Do you want to format it now?" If they check the properties of the disk, they would find the file system of the disk is RAW. Besides, both the used and unallocated space are showing 0 bytes. And they would even fail to check and repair the RAW disk by using "Error-checking" in tools or using the chkdsk command.

When the file system is RAW on a hard drive or external storage device, what is wrong with this disk? Generally, a RAW disk indicates:

  • The DBR (DOS Boot Record) of the hard drive is corrupted
  • Or the file system of the disk is corrupted

Besides, when your disk becomes RAW, you cannot access the files on it and use them as usual. Thus, it's necessary to know how to repair a RAW disk.

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.

So you should prepare another disk to save the files.
