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.
