The term RAW disk refers to the accessing of the data on a hard drive disk (HDD) or other disk storage device or media directly at the individual byte level instead of through its file system as is usually done. Users cannot access the files on the RAW disk and if a disk reads as RAW in Windows, possible (but not all) symptoms are:
Invalid media type reading drive.
Abort, Retry, Fail?
File system is displayed as "RAW".
Windows may ask if you want to format the drive, such as warning "disk not formatted. Do you want to format now?" As the follow picture.
File names contain "weird" characters.
"Sector not found" messages.
Flash drive or pen drive partition is more likely to become RAW format, as power supply, drive interface error and other reasons could cause flash drive become RAW easily.
Firstly, in some situations it may be technically possible to recover a RAW disk. Format may solve your RAW disk problem and let you access the disk again, but all the important files on the RAW flash disk will be lost. Although data may be recoverable, it will be more difficult and recovers fewer files after you formatted the RAW partition. So when you encounter this problem, don't format the RAW partition. You'd better perform pen drive data recovery to recover files first, and then format the RAW drive/partition to access it.
Secondly, if you have formatted the RAW partition, don't write any files to this partition again, as it may make files corrupted and cannot be recovered again.
