By definition, RAW means unprocessed, and an RAW partition means a partition that has not been formatted with the file system FAT16/FAT32/NFTS or etc., and cannot be recognized by the operating system. An RAW partition can be caused by various reasons, such as various attack, formatting error, bad tracks, DPT damage, power outages and so on.

How to Deal with RAW Partition

Although Windows cannot get access to the RAW partition, there are still a few ways that can be used to cope with this issue. Here are four feasible solutions.

Method 1: Delete RAW partition and then recreate.

Run “compmgmt.msc” and choose Disk Management, then you can see the RAW partition. Right click the RAW partition and choose “Delete volume”. After that, you can recreate a partition and execute “Format”.

 

Method 2: Only for RAW partition which is originally in NTFS format.

Run “control folders”, and uncheck “Use simple file sharing”. In this way, the Raw partition regains the “Security Option”. Last but not least, reset the user permission.

 

Method 3: Rebuild Partition Table.

Use Windows Built-in Disk Management to check whether there is something wrong with the partition table. If YES, rebuild MBR. Or Use Partition Magic or Partition Wizard to recover the RAW partition to FAT32 or NTFS.

 

Method 4: Format RAW partition and then recreate.

The most direct way to deal with RAW partition is by formatting it into FAT32 or NTFS. Usually, NTFS gains more popularity than FAT32 in storing large files. Run “compmgmt.msc” and choose Disk Management, then you can see the RAW partition. You need to right click on it to choose “Format”, and select another file system like NTFS to apply your change. Last but not least, you can run an antivirus program to have a full disk scan to remove all traces of the virus.
