Best Method to Restore Data from RAW Partition?
RAW partition means that the file system is corrupted, system can’t identify whether it is FAT, NTFS, EXT2 or EXT3. Under this condition you cannot access this RAW partition and you can’t use files in this partition like documents, photos, audio and video files and many other file formats. Raw partition refers to the access of data on a hard drive or any other data storage device directly at the individual byte level instead of its file system as is usually done.
When the partition becomes RAW it usually reports an error as below:
- The disk in drive X: is not formatted.
- Sector not found.
- The type of the system is RAW. CHKDSK is not available for RAW drive.
- Disk/Drive is not formatted. Do you want to format it now?
- Invalid media type reading drive. Abort, Retry, Fail?
The partition becomes RAW mainly due to file system corruption. File system is the main component of any OS. It is responsible for managing files and directories on the hard drive. If the file system is damaged due to malicious virus infection then all the hard drive partitions become inaccessible, computer may become unbootable and the data becomes inaccessible. When the file system gets damaged the file system and the drive becomes RAW and windows won’t be able to recognize the RAW file system. This peculiar behavior results in severe partition loss situation and you need partition recovery utility to overcome this problem.
The file system gets corrupted due to following reasons:
Improper system shutdown or start up: Shutdown the system through one of the system shutdown commands; these sync the file system first, saves the data and safely quits all the applications running in the system. Shutting down system forcefully results in improper closure of file system and corrupts file system. Improper start up procedures never checks the file system for consistencies (fsck) before mounting it and never repairs any consistencies discovered by fsck. Frequent power outages results in forceful system shut down resulting in corruption of file system structures.
Virus Attack: Virus infection is the main reason for file system corruption. Virus replicates themselves and spread to maximum files in the PC including system and user files. This causes corruption of file system and hence the partition becomes RAW. In such siruations, you can restore Windows partition using partition recovery software.
File system updates: When you update the file system the OS doesn’t write the file system updates directly to the disk after file modification. It writes the updates to buffer cache which is much faster than writing to the disk to save the time. When the buffer cache fills up the information along with the appropriate inode numbers to identify files then it is written to the disk. If this process is interrupted before the buffer contents are written to the disk, the file system on the disk becomes corrupted.
Even though hard disk partition has become RAW you can easily recover data from that partition with the help of partition recovery tool. This outstanding application recover lost partition from external hard drive on Windows 7, Vista, XP operating system. Many times you may opt for quick formatting on western digital hard disk to get rid of virus, to enhance the system performance but formatting results in loss of data from disk. In such cases use partition recovery tool to restore quick formatted partition on western digital hard disk. This tool can locate and retrieve up to 300 file types based on their unique signatures and allows you to manually add or edit the signatures to non listed files.

Precautionary measure to prevent data loss:
- Always keep the back up copy of data so that it can be helpful to restore the data in data loss situations.
- Use uninterrupted power supply to avoid power fluctuations leading to improper system shutdown.
- Install good anti virus program and scan the system regularly to prevent data loss due to virus infection.
- When you find that the file system is RAW don’t format the partition or write new data to the partition otherwise it would become difficult to recover lost files from RAW partition.
