"CHKDSK is not available for RAW drives"? Fix It Now!


Hi AnyRecover team, I'm facing with a very tricky problem. My USB became RAW this morning, when I tried to fix it with chkdsk command, it told me "The type of the files system is RAW. CHKDSK is not available for RAW drives". How can I bypass this? Any help would be much appreciated!


Sometimes hard drives or other storage mediums become inaccessible and show RAW file system. The solution requires you to format the drive or fix errors via chkdsk command of Windows. The problem is, chkdsk command does not work for RAW drives. So, you need another way to fix the issue.

What Does "CHKDSK is not available for raw drives" Mean?

Windows can read and access certain file systems such as FAT, FAT32, NTFS, etc. But when there is no file system (its RAW), Windows simply cannot read it. So, when you use the chkdsk command to check the drive for errors, it simply cannot read it and gives the above-mentioned error. This problem may occur on internal hard drive, external hard drive, and even on SSD. A drive can become RAW due to bad sectors, corrupted file system, or some other reason.
