RAW means the partition is not ready to be accessed or explored. So it is not an accepted file system in Windows, Linux, Mac, Android, etc. A disk can turn to RAW due to files system damage. Thus RAW drive brings about data loss issue as it cannot be opened.
Why chkdsk is not available for RAW drives
CHKDSK, short name for check disk, is used in Windows to scan hard drive and find problem which is a useful utility for disk maintenance and troubleshooting. However, since chkdsk command fails to repair file system errors, RAW file system is no longer repairable. You need to recreate file system instead of repairing it.
Therefore,
we have to format RAW drive to create new file system for the corrupted
partition. Formatting can be done in Windows Explorer or Disk
Management, but formatting will erase all data on the RAW drive, which means you will lose everything. Thus
it’s not recommended to format it if there are important files in RAW
drive. The first and foremost step is recovering data from RAW disk.
