Part 1: Why CHKDSK Is Not Available for RAW Drives?

CHKDSK is an inbuilt utility command in Windows that is used to fix a hard drive (or a partition). It can get rid of various kinds of logical errors and can even fix a corrupt file system. Though, the command will only work with file systems that are recognized by the computer like FAT32 or NTFS. If the external drive is in a format that Windows can’t recognize, then it would be categorized as RAW and the command won’t be able to process.
